The name of the board is usually on the middle or back printed in white, or is on a small sticker on the board. If not, if you call zenith they can probably tell you the part (say your asking for an estimate on what the part would cost) and check ebay or something.

Tv will not come on


I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.6_17_2012_3_16_16_pm.jpg6_17_2012_3_16_36_pm.jpg

Picture focus getting worse & worse; now sound becoming intermittent


You are most likely getting bad capacitors in the main power supply as well as the sweep power supplies. Looking at the age of this unit, the cost to replace the power supply, it will cost you about 350 to 450 to repair this set. You MAY ALSO need to replace the High voltage/ sweep board as well. The best way to properly tell would be to call out a factory authorized Zenith repair center. They should have all the boards available to test the TV with. That would also be a bit more to repair. In my opinion, the cost would not justify the repair. Good Luck with your TV set.

Rear projection tv wont come on. PLEASE HELP


If the set uses a lamp it MAY have a color wheel--when they fail you get a high pitched whine and or grinding sound--also often described as a fan like noise.

this is a part of the optical light engine and may not be sold as a part by itself.

If you remove the lamp and look where it faces you should if it is there be able to see it--missing any pieces or shattered and it is bad.

Picture and sound on my old zenith bigscreen flash on and off.


Sounds like a power problem to me. Possible shorting out inside the tv. If its old I would recommend discarding this tv. The price of repair costs are really high for TV's. You can probably upgrade to a flat panel for what the repair cost would cost you to repair this older tv.

Does it turn off and on as if you were pressing the power button? Or does it happen really fast? If its happening as if you were turning the tv off and then having to wait for it to come on again I would say its the power supply which is probably going to cost you hundreds in a repair shop. However you could possibly find a power supply for it on ebay buy searching for the model number and brand in the search area of ebay. Putting a power supply in a tv isn't really that hard, unless there is something in the way to get it in or out of tv. Usually it just involves unscrewing it from the chassis and unscrewing the hot wires and ground from the supply...then putting the new one in and screwing them back down.

Zenith 44" LCD TV


The yellow spot is due to the BLUE LCD and/or lens assy cracked, reason, to much HEAT! The blue is the darkest color and hold the most heat, so it goes first, always! In some cases it’s only the lens, however most of the time LCD is damage to. Parts are available, however install and alignment is timely. Quick fix is the complete light engine, which for model# E44W46LCD is part# 3141VSN916C, which customer cost is $1,449.27, wholesale for about $1,065.21. Rebuilt, if you can find it around 850.00 to 950.00. However the rebuilt does not always look as good as factory. My advice, TRASH set. This part will fail again in about 3 to 4 years, unless you watch a lot of white video. Remember, on a black or dark picture, all three LCD are blocking 100% of the light, causing extreme heat within the light engine. It’s a bad design.

replace the convergence amps and any blown resistors or pico fuse on the board. this is a common problem of rear projection sets this repair is not for the amateur have it done by a pro. the cost of the repair may be around $ 350.00. if you so choose to do the repair yourself, look for the two large ICs on a large heat sink (stk392-xxx).repalce them use heat sink compound on the new ICs and check the resistors around the ICs with a DVOM and check any pico fuses for open.
