Zenith D52WLCD 52" Rear Projection HDTV-Ready Television - Answered Questions & Fixed issues

It is in the manual. Or call Zenith Tech support.

If its possible you will need to locate a service manual to do it---a reset is available only on some sets and will not cure screen defects---only thing I have encountered is if it has one--it will correct communication issues between the engine and main chassis.

REPLACE BULB AND PUT IT BACK IN, AND IT WONT COME ON... WHAT SHALL I DO

Replace it. It is not worth the approx $600.00 to repair, new 46" LCD flat go for less then that. Check Costco and Best Buy have great prices. Also the color and clarity of the newer flats is far superior to any rear projection.

The cost to repair (about $600) this problem will be close to the cost to replace it. I advise you to look for one of the new LCD flat screens, a 46 inch can be had for about $500 if you watch the sales.

No,the tv message said replace lamp wright?Yes,mean the tv projection lamp is the causes and the problems.The tv projection lamp life span have ended that why the tv it is not holding a stable tv projection lamp picture.All throught these causes,does the tv make alot of clicking noises too,when the tv projection lamp is it on for 30 sec.and shut it self off?Yes,than the board that call the Ballast board it is also dead too.This Ballast board only job are to ignite the tv projection lamp only.Tries websites like Partstore.com,Ebay.com to buy a new tv projection lamp and a new Ballast board too for the replament too,if this tv causes have alot of clicking noises,when the tv is trying to ignite the tv projection lamp.

Try this. Type in the model number on Amazon. That is where o ordered mine

Hi,

Yes, the procedure you've entered, pressing the "?" key at the remote control at standby mode, follow by pressing 9,8,7,6 is correct to reset the lamp timer.

Another is by pressing and holding the "Menu" key at the remote control until the "OSD" (on screen display) menu disappears follow by pressing 9,8,7,6.

If the unit still keeps turning off, let me know which led light(Operation, Lamp, temperature) at the front panel lit solid/blink and its color to determine where the fault came from.

try this if you have the remote control, press the menu button continuously, The "OSD" menus will disappear then press the "9876" and press the "OK" button to enter "ADJ" mode you will see "Lamp Life Time" Then set the time to "00".

it sounds like you have a light engine problem with your unit possibly a lcd plate issue if you have it under a extended warranty id call for service if not look for a light engine replacement

Your power supply is failing. Seek out a television repair shop in your local area.

usually that means the bulb for the projector is out there usually around 100 dollars! it could also mean the color board is out. so open it up look for the bulb if it looks blown then just buy the bulb and you got a nice tv if not junk it!

convergence settings buddy normal tv repair for under 100 dollars its a normal thing should be adjusted every 3 years but some tvs can last 10 years or even longer or sometimes less than 3 years its just your luck

sounds like your light engine is the problem. (optical block) there is a serious of light paths and one of the path is the problem. it can be the a light filter or lcd panel. sorry to bring bad news but this is not a DIY repair unless you are very good in electronics and light filtering plus panel aliment. plus finding those part is very hard. there are places that you can send the engine out to be rebuilt but they are expensive. (250-1000 dollars) sorry for the bad news. i had a sony that was doing the same thing and i kept calling them and they finally sent me a new tv free of charge. hope this helps you out.

Ur tv some how is setting on sleeping timer is on.Goto ur tv Menu.Resetting everythings all functions in the Menu.This will stop the auto on.

I persoanlly have the same problem and as a tech I can tell you like me, I am having to get and optical block/light engene. I found one for mine at www.discount-merchant.com for 199.95. My set is a little different from yours, so your price may be higher.

Yes,u still can hear sound,if the projection bulb is dead.The Ballast board might also dead dead too.The Balllast board help to ignite the projection bulb.

No,colors misalignment,shodows pictures and 3D pictures are not cause by the projection lamp.It cause by the tv convergence board have 2 STK convergence ICS and some or all it resistors are dead.The shop will cost u $300-350 for the parts and labors.

Probably not - invest that money in a new LCD tv with warranty.
