What do I have to do to repair my Toshiba smart LED TV


Hiu Annick,
The cause of this problem lies in the power supply board of your TV. Most probably the main dc filter capacitor, the thickest one on the whole board, 150mf/450v should be defective. If you open the back cover and check, you may find this capacitor swollen up at the top. Apart from this you may find some other small capacitors also gone bad.
Another thing, please never leave your TV in stand by mode for long hours, specially when you are not home. Any power fluctuation during this period can harm your set.
A word of caution, please be very careful if you want to do it yourself, because your set is a big one and any wrong move can damage the panel.
I hope this helps.
Good Luck.

this may be a problem of a loose component, looking through the main board and soldering loose components, IC, transistor, all components, just have patience, this may solve the problem.

DS27930 Screen Goes Black


There is no vertical card inside this set. Its the simple unexpensive vertical output iC. you most likly have a cold solder connectiion, on or about the flyback transformer, or video circuit in the TV set. Good Luck Please do not forget to rate this thread.
