Question about Toshiba 51H93 51" Rear Projection HDTV
This set uses what is called a "Hyper" board; it processes all signal from all inputs.
These sets have a history of tiny capacitors on that board failing, called surface mounted that dry out and fail.
The classic pattern when this problem happens is the period until it clears up gradually gets longer and longer.
The board is no longer available and only available if removed and sent out for repair.
Probably not worth doing as the last one I saw cost over 200 for a repair/rebuild.
I do not like giving bad news but this is what you have.
If this information told you something you did not know rate this solution as very helpful as I do this here for free.
