Other than that, it is excellent and very clean with no marks, scuffs or scratches or dust. It comes with manual. We never used the projector or the LCD panel.

It comes with only one lamp installed (this is how 3M sold this unit) with the other lamp socket empty. The post assembly that holds the projection head aloft is hinged against the body of the unit, and a loosening turn of a knob swings it into place.

Have cleaned but cannot remove. Available for collection any weekday from tomorrow. There is a brand new bulb in it. Please can you assist with a repair. It works in colour using video-in and still works in colour when using a hdmi cable for sound via the dvd 5.1. But if I change the source to hdmi (say DVD or laptop), it becomes monochrome. I have tried different hdmi cables and different hdmi sources. I have tried to clean it of dust. The next issue is that it starts remains on for less that 5mins makes a loud nose and then switches off. The projector has a problem starting up. When the power is switched on there's the usual click and the fan starts up a few seconds later - only to stop after one or two seconds. The lamp and temperature warning lights are both flashing red, indicating a malfunction. Can you give me a quotation. I have had it out of the ceiling and there is no model number or branding on it. It has been running off a third party controller which still appears to be working so I presume the screen itself is at fault. Fitted a new bulb, but just cycles round, shutting down before lamp comes on. Red light on lamp button. Please can you give an estimate of repair cost before I go ahead with the booking.I have power issue in my Epson. I've changed lamp for new one and still my projector is not starting. If urgency necessitates higher cost then would rather wait but have no TV. Please do not replace lamp unless 100 necessary as has only just been replaced by brand new one and another is en route. I've recently purchased a second hand Optoma HD151X and was wondering how much it would cost to fix a problem with it. It seems to have dust and debris inside the light path. This is visible when the projector is turned on with no signal and putting the focus wheel at one extreme brings the debris into sharp focus. With an input via HDMI the marks are still apparent, but less so.
argo-naut.com/userfiles/files/casio-edifice-4334-efa-121-manual.pdf

When the image is focussed, the debris marks become more indistinct, but they are definitely still there. On a pitch black screen, the debris marks become white dots. Occasionally the machine emits a high pitched noise. This is not too loud, but may be indicative of another issue. Let us know if you would be interested in getting detailed proposal. We look forward to hearing from you soon. Also the wireless HD is intermittent. I need info first. Please advise me of your charges. Fixed price? Do you require payment up front or will you advise me of repair cost after you check the item and I can then refuse ( pay postage to return). Red light I think one of the fans requires replacing. Please advise us if you can assess and repair it. The other makes and models I will send to you after you make contact. Could you please confirm if you think it is fixable and how much -approximately- would cost. I could deliver the projector to a London location if that makes it cheaper. Could you please confirm if you think you could fix it and an estimate how much would it cost. I think it’s the bulb that’s gone - when it broke there was a burning smell and total loss of picture. This is not urgent - so happy to wait. Could you give me an estimate of cost. I had an issue a few days ago like this but I'd left the room so I didn't get the message and it switched off. I swapped out the bulb thinking it was that and obviously it's a fan issue. Is this something you can repair. I wonder if this can be fixed. Three vertical yellow lines and one blue vertical line appears on the screen. It started off with one yellow line and the other lines have recently appeared. I have also noticed a faint horizontal black line. Could you please give me a repair quote. Sometimes when booting up the screen would flicker until the colours stabilised. Now it turns on and they do not such that it continues to flicker. The colour wheel was also replaced 13 months ago. The unit is about 2.

5 years old and purchased in the US. Sometimes on start up it would flicker until the colours stabilised to the correct ones. Now it boots up and does not stabilise. I assume it needs to have a new lamp put in. About 13 months ago the colour wheel was replaced. The unit is about 3.5 years old and was purchased in the US. Please include in the reply and estimate for total repair cost and estimated duration. This has resulted in a cloudy picture being produced. I think I need to have it thoroughly cleaned throughout. Is this a service you provide. If so what are you lead times and costs. Fans are loud which makes me think they might be worn.If so can you give me an idea of cost to repair. I have an Optoma HD25e and there is no picture, the bulb is on but produces a very feint screen display. Is this something you can fix. It seems to be the power issue as it doesn’t turn on anymore (not even the power led indicator). Do you repair Xgimi projectors. Can I get a rough guide for fixing an issue like this. It still has the lamp and power led’s illuminated red. Is it possible to get a rough quote for repair cost please. I'd love to get it properly up and running so I can look at their slides with them once we can all meet again and before my mum slips further into dementia.Do you think you can help. Or point me in the right direction. Could you please give a repair quote. How much is it to replace the lens. Nothing too serious. Just a clean up from dust inside. Wondered if you could take a look as to why this is happening. Bulb needs replacing and a general cleaning please. I have a Mitsubishi HC7000 LCD projector that has some dust blobs. It wasn’t too bad but there is no one pretty large one that spoils the picture. If it’s possible for you to work on this projector could you please let me know the approx cost of:- 1. Removing dust from the LCD panels- eliminating the dust blobs (just this job only) and:- 2.

Doing a full service on the projector removing the dust blobs but also including other things like making the iris quieter, and fan a bit quieter too, if possible, and any other appropriate servicing. I saw a video of how to dismantle this projector but it just looks far too complicated for me to try. Tried this evening, as I switched on it made a slight noise and now no power and will not switch on. Checked fuse, that's ok. Maybe main board has gone. We are looking at a quote to fix the screen or replace it if it in not fixable. We have requested a return pick up many times without success. Please would you arrange a return pick up to rectify. Then the projector stops projecting and can only be turned off by unplugging. From online research I think it's a fan or temp sensor issue. Would you be able to give me an estimate cost of repair, please. Please confirm if you would like the machine. After getting a replacement JVC lamp unit same issue happened. Not always noticeable but easier to notice on darker scenes. It’s completely split down the middle. I wondered if you could email me your thoughts on what this could be and weather it’s worth sending the unit to you. Projector powers up and bulb works, image appears and then after around 2 minutes it cuts off as if an overheating switch has triggered. Before this fault started my daughter left the projector on with cupboard door shut in front so it may have overheated. Can you look at the machine, the onboard power supply fuse has gone. I also have a new colour wheel should it require changing. There seem to be two things wrong with it:- 1) it’s noisy - the noise goes away if I squeeze it gently just where the air vent is underneath.Would be great it if could be fixed, so please let me know if you think it’s worth a go. Are you able to service this unit. Crossing fingers for a YES:). Please could I have a quote for repairing this. We then can't turn it back on unless we leave for a few hours.

I think it may be an issue with the HDMI port, maybe a loose connection. I have taken one apart, in order to assess the problem but the LCD is beyond repair. The other hasn't been taken apart but has the same problem. Essentially they both need new LCD panels. Given the present Corona Virus lock down, are you still operational. I emailed a week or so ago about replacing the chip on my benq projector. Please contact me if you're able to help. This is a widly reported fault on Optoma Projectors. Could you please give me a quote for the job. Our conference room Epson projector has stopped working. It was flashing 3 red lights. I changed the bulb and it worked for a very short time and then stopped. It will not come on but makes a 'fan' sound and then the 3 red lights start flashing again. We would need someone to remove the projector from the suspension unit, as well as collection please. How much would this cost approximately. I need to know if it is worth repairing, as it is now 9 years old. Are you able to offer this service. Unsure when the lamp was last replaced or even if it is the correct one. When powered up there is a vertical flashing white line that does fluctuate in colour but is constantly visible when presentations are underway. My Optima projector turns on but no image is projected on the screen. I'm interested in an estimate for repair please and would appreciate contact to discuss. Pretty straight-forward bulb replacement. I've never had it fixed before so I don't know the process behind it all, or how much it would cost. Repair estimate appreciated. The air filters are clear and the internal cooling fans are all spinning freely so we believe the temerature sensing thermistor is defective. How much would you expect this to cost to be repaired. Issue suggests that its power related as turned off when plugging into mains. Have tried replacing fuse in plug socket but to no avail - projector still does not turn on.

I have charged it overnight as we haven't used it since September. It turned on, showed the main page and then the screen went blank and it also will not turn off. I was wondering if this was something you could sort for us. Any honest advice is appreciated. Projector is level - screen is vertical - and I have no keystone adjustment etc. I've fiddled with the panel alignment settings for hours - but with no joy. The best explanation is that there appear to be two slightly misaligned sets of pixels (in all colours). The top of the image is much better (althought not perfect). I have taken pictures but can't find an E-Mail addresss or a way to include them in this message. Is this likely to be fixable. The three main symptoms are: 1. LCD misalignment seems to of increased from original delivery amounts (which was present, but minimal in red only), but is now very noticeable on text, and is making movie viewing a little blurrier. Red, green and blue are all misaligned now. 2. Fan noise also seems to of increased. 3. The lamp dims after 1-2 hours of viewing, which never used to happen. I've had the projector from new (5-6 years), it's never been knocked, and only moved a couple of times for cabling access. The lamp hours is at 2100, halfway through the quoted lamp life of 4000 hours. I tried to remove the dust from my projector myself, but when putting it back together the focus wheel stopped rotating. I didn't snap anything, and it is a mystery to me. I was wondering if it was a problem you'd encountered before, and perhaps if it has an easy solution. Now the projector doesn't project and when moved I can hear what sounds like glass pieces moving around inside of the casing. Powered off fine. Went to turn on, lens cover opens, no fan spin up, no light emitting. Green on light displays for around 30 seconds and then: Standby - Solid red Lamp - Slow, steady flashing amber Warning - Solid red The power switch round the back had flicked off at some point.

I ordered and fitted a new lamp but it didn't fix it. The old one was working fine before and had around 400 hours on it. I suspect the ballast board needs repairing or replacing as that's something that tends to go in this model apparently but I don't have the expertise to attempt the repair. I can drop it off if that's easier. After some time, it splits the screen whereby the right hand half projects blurred columns down the screen. Can you please send me approximate costs of a service to the machine, and also the cost of return to the point of collection (as you quote free collection, but no indication of getting it back). I look forward to hearing from you soon.I would appreciate an indication of prices before committing to works. It doesn't have any problem, just I'd like to be cleaned and serviced properly on the inside. I was wondering how much would it cost. I believe this is usually due to the blue polariser being burnt out. Could you please let me know if would it be possible to arrange this with you, and if so, when. Epson told me that this means it needs a service. So I found you. Are you able to help me. Can you rectify this. This projector is used as a back up to my main projector. I am exhibiting a video artwork for the National Trust at the end of March and will need this projector as a 'back up' around then. I could arrange delivery to your premises in Covent Garden myself as my husband works near you. I look forward to hearing from you. How much will it cost. The projector is at the address given (Holden House). If easier I can drop this into Covent Garden this morning. However I am not sure.
