WHITE PICTURE NO SOUND WATCHING T V PICTURE WENT WHITE

Hi Ralph, you have a bad tcon board or a bad panel, this model had a lot of both panel and tcon issue, finding a board may be difficult and expensive.

Something like this : Samsung TV white screen repair

is this happened either watching a tv channel or even watching dvd movies?. and then does the display only white screen or a totally black screen?.

Check and replace the main power regulator board as card basis. It has damaged.

I WOULD SAY NO ! THE PICTURE TUBE IS PROBABLY AS MUCH AS THE TV IS WORTH. i had a very nice sony trinatron tv. the picture tube whent on it at about 5 years so I CALLED FOR REPAIR AND THE PICTURE TUBE WAS 2-300 DOLLARS. good-day !

Does it only happen when you use your Xbox?

Try pulling the cable in and out between the TV and Xbox

I would start by obviously checking all connections on the back of the tv. Sounds like maybe your Yellow RCA cable might have creeped out. Red and White RCAs are typically for sound and Yellow is for Video. Hope this helps

Ur BD power inverter board is dead.One of ur Capacitor or rmore it dead.U know how to solders?Buy the parts and replace it.Or buy the whole board and replace it.

sounds like the main board maybe going out or is gone and the lamp may have went as well
