Hi,

these symptoms are usually a faulty screen, if you are lucky it may be a faulty T-con board, worth trying if you can get a cheap one.

I wonder the picture was 1 week ago very good
The mistake came suddenly so I think it can be the T-con board
but also can be the mainboard on which is the scaler chip
This is the transmitter over lvds cable and the t-con board is the receiver
but there are digital signals not to measure easily!
thats the problem of all LCD-TVs

jimca007:
Sounds very like a screen ribbon fault ( I think toshiba refer to it as the tape package or something similar ) there was an old thread about placing foam strips on the ribbons to make them contact might be worth a read

thoma:
Can you tell me where is the thread and more about placing foam strips on the ribbons to make them contact !
thank you thoma!Is it possible that toshiba have a problem with some panels?
