Question about Projection Televisions

4 Answers

Hello, My Westinghouse ltv32w1 LCD TV is only 2 years old. Sound is fine, picture is not so good: Initially when TV goes on picture is okay, then after 30 minutes, the image breaks up into verticlal lines and is unviewable. Other times, the color gets distored. There are "hot spots". Bright colors, for example flames in a fire place, become pixelated and lose resolution. Then people turn green and purple. Thank you, Kathleen Fisher

    My posting is listed under projection TV and of course it is LCD.



    I have 4 emails saying 4 experts have made comments, but only one solution is showing.



    How does this work?

    My last solution is listed under the category of projection tv, my tv is LCD. I have no further details to add to my problem, but would like to know the approximate cost for the replacement part and whether it can be done by me.

Hi,
Symptoms of tv shows problem in LCD Controller board and hopefully fault can be fixed by replacing LCD Controller board.
Board can be purchased from Part Store on $74.22 only.
It would be better to get service of qualified tech person for board replacement.
Regards,

The behavior from your LCD means that there could be a power supply failure starting to developed due to leaky or dry capacitors.
The power supply might not be available anymore since is not being manufactured for this LCD model.

    Power supplies fail in about 95% of the time.

    The cost for the repair will vary. I would suggest to contact your local service repair center and ask them how much it will cost you to have it fix.

    There are repair service techs that could fix the power supply for around $100.00

Verticle lines are most likely a bad tube or convergence problem. You will not be able to fix this your self . I suspect a bad convergence ic

    I suspect a bad convergence ic cost for parts are around 30$ service
    charge around 150$ to fix. At least know when you call a service person you
    will have

    a good understanding of problem.good luck.

  • dewan nafees ahmed Sep 17, 2008

    Try a hard reset a couple of times and see if that helps. If not, you will need an expert tech to look at it.



    Reset is best done by disconnecting the power cord from the wall outlet
    for 4 hours; then power up. Do it twice. Then let me know - - or
    all in a repair expert.



    It is not an adjustment; it is a malfunction

  • dewan nafees ahmed Sep 17, 2008

    it can also be a malfunction of either the vertical deflection system or the auto format switching circuits.

Rca hdtv 52inch will play fine then picture goes black but still has sound.. after a few mins.picture will come back on , and will play fine could last all day or may go out again in a few mins.


My tv is relatively new, but the bad thing is that I had an old; big screen tube type rca model; home theatre, that was heavier than a car, and it went out, due to the cracking and popping sound, off sometimes, and back on.
What is strange is the new tv now, the hdtv, light weight, about five years old, is doing the same thing. Actually, now, the power will not even come on. The lcd green light in the front goes on and off.
Take no offense, but I thought I would not have these problems anymore. What do you suggest?

Pink bar across top of tv screen


This could be from 2 things. 1 is the optical block is going bad or 2 you got a peice of dust blown in from the cooling fan and its blocking the color filter internally. If you are capable you can take the tv apart and blow compressed air into the color block and remove the dust. Hope this helps

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.

Just puchased grundig LCD TV,model glcd2205whtdv, tuned the tv stations in okay. But every 3 minutes the LCD display goes off, sound is still there. Use the remote to turn unit off then turn on again,...


Hi,

Initially it would appear that you have either a LCD screen problem or your CCF Lamps goes out. Of the two I would suspect more the CCF Lamp which could be the lamp themselves, the inverter that powers the lamps or the logic circuitry that deactivates the lamp.

Additionally, this would be heat related or even possibly a loose connection somewhere in amongst the areas above mentioned.

Considering that the unit is new and presumably under warranty, perhaps your best bet would be to call it in for service by their authorized service personnel. Any diagnostic/corrective action would require that the back of the unit be opened for a look & see which of course would void your warranty.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
