Wavy picture on all video inputs except component video toshiba 57h82
I had a slight wavyness happening on the top section of the screen that got better when warmed up. Also had a wavy picture on all video inputs across the entire screen. Then replaced the caps on the hyper board & it solved the wavy section on the upper part of the screen but I still have a wavy picture on all other video inputs across the entire screen. The component video input is crystal clear. If any one has any answers what else is wrong? Please let me know?

Is a common problem. Your hyperboard has failed. You can get a repair kit from www.TvRepairKits.com or buy a used hyperboard - but it will also fail someday unless it has been repaired with better parts than what the factory supplied.
this is a known problem with these toshiba tv's, they will do nothing to help you we should form a consumer group and complain to Washington! The part that needs to be replaced is a hyper pcb,pd0637and is available from Tritronics, in Miami Fl.phone #1-800-365-8030.the part cost me $263.00
