The picture is wavey tried everything and i am unable to fix can u help me?


The hypeboard has failed. There are about 12 capacitors (surface mount) that need to be replaced. Unless you have very good soldering skills you shouldn't attempt the repair. The hyperboard will be marked with MVPU14 I believe. It should be located directly behind all your input connections in enclosed in a metal can. It is about 8" inch square module that plugs into the signal board.

The metal housing will need to be unsoldered from the signal board, before you can remove and service the hyperl board.

When turned on, the screen has waves in it across the top and flickers. It is unreadable. When the TV warms up it seems to be better but is starting to flicker or flash all the time now.


Hi,
Your Toshiba TV has hyperboard inside and there are few electrolytic capacitors (may be 10) that need to be replaced.
If you are comfortable with soldering parts in PCB then go ahead or ask help to any friend that knows electronics stuff repair.
Let me know further query.
Thanks.

Tom,
I'll send the svc manual directly following this post, but as a word of caution be EXTREMELY careful removing the smd caps. You can easily damage the traces and make the module useless.

Toshiba 50H82 hyperboard caps


Service manual won't help much in the hyper board and that's likely the problem.. Simply remove the hyper board and open the can. Inside you'll see a number of smd caps. There are 11 10mf/16v that need to be replaced...
