Question about Toshiba 51H84 51" Rear Projection HDTV-Ready Television
Over the the last few months the picture on the TV has been pixelled on starting it up. This used to go after a few minutes, but now its at a point where it takes about 15 minutes to get a decent picture and even then its pixelled round the edges. Picture tuning and Convergence make no difference. Can anyone help? If it needs a spare part where can you get it from and how much will it be?
SOURCE: bad picture until tv warms up
this is a very common occurance in these sets. toshiba has issued a servece bullteen with this set. Sorry to tell you this but this is a problem with some very small capacitors on what is known as the hypermodule. in my shop we fix 2 to 5 of these a month. you really have to know how to solder. Idealy replace the hypermodule is the best way. but......that board is hard to find. so we replace these 11 very very small componets with twezzers and a big magnifier. we charge about 250 to 350 for this repair.

This is a model first sold 2002.
They have a history of the Hyper board failing. Usually noise or lines in the picture and the warmup time gradually gets longer and longer.
This board processes all signal from all inputs inside the set and is no longer available from Toshiba.
The only way to get one is from a national company called PTS Electronics who rebuilds or repairs them--cost for rebuilt board is about 220 plus shipping and part number for this model is:
I have a service bulletin with photos of the board on my computer.
It is a financial decision, not a job for the average do it yourself person to attempt.
Let me know if you have questions or need help.

If you get shaky picture with lots of lines (as shown in below image) in your Toshiba 52H82 tv then it is problem of bad capacitors in Hyper Module, replace these capacitors in hyper module to solve this problem. Hyper Module is little circuit board mounted vertically on signal board and located behind inputs jacks.
Capacitors replacement needs good soldering skills with proper tools, if you do not have soldering parts in circuit board experience, local tv repairman will do this job in proper way.
