Question about Toshiba 65H84 65" Rear Projection HDTV
LINES or noise from left to right etc. This is a classic problem in a lot of these sets--that this clears up after a while is also typical---the period will gradually get longer and longer for it to become normal.
This set uses a Hyper board for all signal from all inputs---about two dozen tiny surface mounted filter capacitors on that board---they dry out and lose value---flat caps will when hot attempt to regain some of the value they should have.
Board is no longer available from Toshiba, only way to fix is remove one in set and send out for repair to someone like PTS Electronics.
I have seen experts try to replace the tiny caps--usually several are off value or open---cheaper to send board out. Last one I saw cost was about 200 for rebuild, keep in mind same problem will happen again in 5-8 years.
Let me know if you have questions and if this told you something you did not know, rate this solution as very helpful as I do this here for free.
