Hi,
It seems tv got problem of bad capacitors in hyper module, please replace all bad capacitors in hyper module to solve problem.
Hyper module is long circuit board covered with metal shield located on signal board of tv. Capacitor replacement requires good soldering skills and if you do not have such experience, please call local tv repairman for that job to avoid any damage of circuit board.
Hope these info will help you.
Thanks.

When we turn on our Toshiba 50h81, it will work ok for 45-90 minutes, then without warning, the picture and sound will go off and the power light blinks. We have to let it set for awhile (I've never timed...


These Toshiba TVs have a problem on the power board that causes this issue and it is a common one. There are several capacitors on the power board that seem prone to coming loose over time. When they lose connection for a moment the TV's protection system steps in and cuts off power. This causes the 'blinking power light' issue. The last one I repaired was a 43V71 model and I re-soldered one loose capacitor on the power board and it has worked perfectly ever since. Toshiba put out a service bulletin on this problem. It is well known and well worth fixing.

Toshiba 50H81 Has Power but No picture or Audio


ok i'm goin to need more info about your problem. you stated fuses and didn't say the location numbers of the fuses. Also, have you rechecked your fuses to see if they are all still good? 3 fuses sounds like more then one problem. once you tell us your loc#'s of your fuses, we can look into your problems.
