Default Can LCD screens be repaired...

or is it time for a new TV?

26" Westinghouse LCD quit displaying after about 30 seconds this morning. All other functions still work.

If powered off then back on, the screen turns on for about 2 seconds then black.

This one is 3 years old (and was $1100 when new). I know replacement 32" are about a third of that now.

If the LCD panel was cracked or you had dead pixels, then no, you would have to replace the LCD panel, which is the single most expensive component in the TV.

Do you still get sound and can you still change channels? If so, it's likely either the backlight for the display died or the power supply to the backlight died. If the TV is totally dead, likely the main power supply died.

If it's a problem with the backlight, you can often see if the TV is actually working by shining a bright flashlight on the display from various angles and looking at the display from various angles. If you get the angles right and look closely, you'll be able to see the picture.

If it's just the bulb for the backlight, that can usually be replaced inexpensively--sometimes they are even user-replaceable, so look in the manual and see.

If it's the power supply for the backlight, or the main power supply and you are able to replace it yourself, it could be worth it, but if you have to have a tech do it, it will probably cost you as much as a new equivalent display at this point--many techs won't even open up an HDTV for less than $150-$200, and that doesn't include repairing the problem or the cost of the parts.

Additionally, was there a crackling sound? or a sizzle when you turned it on? was there smoke? Could be a power supply issue, could be something shorted out. Need to know a bit more info, man. The good news is you get to take advantage of some of the upcoming black friday deals (provided you can wait that long).

All of the other parts of the TV still work.

No sound or smell, so I doubt that any component fried.

I did find a guy here in town that will look at it for $79 and repairs are parts only after that.

I plan on buying a Toshiba 32" 1080p set fron Sears (due to their price + 10% less policy) for $629 and using the 26" in the bedroom assuming it can be repaired.

I will keep you informed.

Update on this issue.

The backlight module went out. One of the 7 ballasts burned and they are all inter-connected.

The module was on back order for 3 weeks, and just came in. Repair guy said that it was a nightmare getting the boards swapped out. Took 3 hours.

So I now have 2 HDTV's. The new 40" Samsung and the 3 year old Westinghouse. The Samsung will stay in the living room and the Westinghouse will replace a 19" tube in the bedroom. I am using my PHD-200 digital tuner on it with the standard cable and get all 58 analog and 8 HD QAM channels.

The module was $139 and labor (flat fee based on screen size) was $79.

Not bad, I think...

If it was built by human hands, there is a good possibility it can be repaired. How much are you willing to spend?
