1 Answer

I have a wd52628

First I am wondering what kind of chassis is this tv and second when I changed the lamp all of a sudden there is a noise coming from the same area as the the lamp. it started to just be a faint noise and now it over powers the tv. the pic is good except the color is not very good but a good pic and the sound is great. What is wrong with this as I cant stand hearing all the noise to watch tv. Please help its a wd52628. Thanks

    its like a raddleing noise and if I put my hand over the cover where the lamp goes in it goes away a little bite but it is still there and raddles real loud. It goes away when the lamp turns off. The color on the tv is faint in some spots too. And now that you mention the fan it stops when that stops.....and it starts when the lamp powers up

    There should be NO NOISE coming from the lamp area. The lamp is worth $200. You should get a tech to look at it. Did you vacuum out any broken glass/dust/debris before installing the lamp? The noise could be a high voltage arc. This needs to be fixed. This could be a damaged fan. This should be fixed. This could be a power block about to blow the new lamp. This should be fixed.

This area of the TV is a cause of some expense in rear projection.
The fan controls the temperature of the lamp. An obstruction keeps the fan from coming up to speed.
The power block controls the power the lamp uses. This helps keep the glass of the lamp from breaking breaking.
An arc is a badly mounted lamp or a lamp defect.
Dust build up can cause overheating.
Most of this area cannot be serviced by a non-technician.

No picture or sound mitsubishi 62525


Capacitor failure is the most likely scenario the FMT ans Signal PWB would cause the picture interference and the power pwb would cause the lamp light to turn red and give a 34 code when the device/ input and menu buttons are pressed in together and held for five seconds. That chassis has issues with every board in the chassis having failed capacitors you can get repair kits for the V26 chassis at the follwing link that come with instructions. Your model is the V26 chassis. Heres the link.

Red lamp light stays light


I doubt that it is the optical assy. it sounds more like a chassis problem either on the DM or the FMT board.

check out www.tv-techs.com
if it is a chassis problem it will cost about $250.00 plus shipping one way to fix the chassis

STATUS LIGHT SOLID RED ON 73 DLP MITSU MODEL WD73735


The colorwheel is your problem. To confirm this, unplug the tv, then listen thru the air vents in the back as you plug the tv in. You will probably hear a ticking sound. If you do, that is the colrwheel. If the colrwheel is working, youwill be able to hear it "spin up". It will be a sudden high pitch whine. Let me know if I can be of further assistance

Buzzing is usually indicating the color wheel is defective. Or it could also be the lamp fan malfunctioning as well. My quess would be the color wheel as thats a fast moving part which is prone for bearing failure.

Turning on problem with Panasonic Viva PT-43LC14


Sounds as you have a bad ballest. The ballest is the power supply that turns your lamp on. You can check your lamp by removing it and it should be clear and no broken pieces of glass. With the lamp removed install the cover and turn it on you should hear no noise and when the power light turns red you should see a LAMP red led blink every 5 seconds. If no noise then the lamp is bad. If you do hear noise you have a bad ballist. Hope this helps. Frank
