I have a 52" westinghouse


Ok you have a lot of things going on here. Your first thing with the lines can be your T-con board or your Signal board or the screen itself. The second thing black screen you would have to be more specific? Is your back light on and you have no image? If that's teh case then I would replace the T-con board or the Signal board. If by black screen you mean there is no light on the screen from the backlight inverter then your BAcklight inverter or the backlight itleft might be bad. and ontop of that you might have the problem that we started with also. You can get westinghouse parts from www.interliquidparts.com You have to order by part numbers so you have to get the number from the actual part of your TV.

JVC 32" D series TV is suddenly black and white


Wow that's interesting, was there anybody watching your home while you were gone? There is a possibility that someone simply turned down the color level with the color control? Check that first. It's an unusual symptom. With composite video, component video or HDMI it's not usually possible to experience that defect. Since the color (chrominance signal) is usually inseparable from the luminance (black and white signal) I would check the color setting first. Other wise your set has become unable to detect that color signal... I bet it's a setting rather than a defect.

Happy Viewing

The color on my tv is mostly pink. Is this


Try a reset to factory defaults. Show some image with lots of white. If it is still pink, it could be the backlights starting to fail. Or a circuit board. To be sure, you would have to disconnect the LCD panel from the board and turn on the set so that you have a blank white screen....with no signal. A pink screen, backlights are bad.

VISABLE LINES IN PICTURE


Bulb replacement will only repair reduced brightness or contrast problem. Sometimes shadows or lines (usually curved or circular) appear in the image if the bulb is weak or faulty. This will show with the color turned off and a black and white image displayed.

Most visible color faults are caused by optical engine failure. Big cost, as the complete assembly has to be replaced.

Occasionally there are video processing or tuner problems that require serious troubleshooting to determine what board has to be replaced.

If the fault is not visible on the customer menu and appears only with input signal viewed, you may have a cable box or other signal input problem. Check various input signals to see if the problem is visible with all inputs.

Running the channel scan with vhf input signals sometimes clears up a lot of problems. Your cable company may have changed or adjusted rf modulators or other equipment and the tv needs to be aligned to the changed signal. Auto tuner scans will take care of these problems.

Hello Fixya, Thanks for being available in the Net!!! I have a mitsubishi tv model #ws-55809 and the picture is funky.... It's like it's cartooned. The words are fuzzy a bit and so is the skin...


Sounds like a loss of picture resolution. There is a circuit board in your TV that determines the type of signal (HD or standard definition) The video signal (picture signal) is routed thru this board. Call a local Mitsubishi servicer and get a price on replacement. It may cost more than its worth.

When I input s-video cable into RCA tv, the screen shows just black & white color, not full color that used to show. I tried to connect my laptop and dvd player with new s-video cable, but it didn't...


Take a flashlight and magnifying glass and look at the S-Video connector on the back of the TV. Check to see that there aren't any pins or other debris stuck in the four holes.

One pair of holes is for the brightness (luma) signal, which gives you the black and white picture, and the other pair of holes is for the color (chroma) signal, which seems to not be functioning.

If there's nothing in the holes, then the internal connection may be flakey. Try gently wiggling the plug on the TV side and see if color returns, even briefly.

Does your TV have other inputs like component YPbPr?

Blue color's showing green....PLEASE HELP!


Try to do some adjustment in the Service Mode (had better ask tv technicians to do it). If not work, you need to replace the Small Signal Board of your tv.

Tv lost color


Your problem most likely is on the signal board is my guess. If your not a technician it would be in your best interest to have him check L2C60 on the signal board.
