We were watching the TV and it just went blank the service man told me
that the parts are almost all back ordered two to four months. Samsung
customer service department said if I fax them the diagnosis they
would send me a new TV to replace mine if the parts were un-available.
My warranty expired a year ago. the service guy is coming tomorrow
2-27-08 I"ll see what happens and let all of you know. maybe a new TV
for the lemon I bought. This could solve everyones problem with Samsung.

You have the typical backlight failure that LCD tv's tend to get. Take it to a repair shop for an estimate, but depending on the size of your tv, it will probably be better to just buy a new one. Sell this one on Craigslist for a few bucks to offset the purchase of a new one.
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.
Sounds like you have a back light fault. Dim the lights in the room, turn the set on and shine a bright flashlight on the screen. If you see a faint picture, you have a back light fault. If you do not see anything, you have a video feed problem. Either way, I would suggest getting the set diagnosed to pinpoint the problem
hi i have a 50" magnavox that has a problem, i was looking at several websites and i find out the dirfferent posibilities.

1) negative image tv turns on and shots down in 2sec flashing pixels on screen dark image has sound but no video screen goes black and then return to normal picture vertical color lines on screen no video vertical color lines with video vertical bars on screen horizontal lines on the image picture goes red after while
IT COLUD BE (X or Y or Z SUSTAIN BOARDS )
2) just left part of screen working just right part of the screen is working vertical and horizontal lines on screen part of screen not working some functions not working no video but has sound functions not working at all
IT COULD BE (LOGIC CONTROL BOARD)
It does sound like a power supply problem but that can be misleading because a problem somewhere else in the TV can be "holding down" the power supply. This can usually be determined by using some isolation techniques.
