Question about Toshiba 57H82 57" Rear Projection Television

Toshiba 57H82 TV

Hi! I was reading the posts you made regarding the Hyper Module on the Toshiba 57H82. We are having what seems to be a similar problem with ours where it is almost a scrambled look on the screen that gradually improves over about 5-10 minutes. I am mechanically inclined so I can do quite a bit. It looks like based on the things I was reading that you can either replace the components inside this part or replace this part to resolve this problem. Is there a way to test if this is definitely the problem? If so, are there instructions available for making this repair inexpensively or should I have it repaired by a professional?
Thanks so much for the help!

    Thanks! I spoke with someone and it sounds like they will just replace the board instead of messing with the caps. They actually stock the boards knowing they need them frequently enough. It's not cheap but I am not sure what the labor would be of replacing the caps or if they would consider it.
    Thanks for the info!

You should ALWAYS consider having a professional do the job, just arm yourself with enough information about the potential repair to make an informed decision regarding your approval for it...
That said, yes,,,, a tech would pull the hyper module and test the caps in question using an esr meter (equivilent series resistance). If the esr is too high the cap is not dissipating voltage at a correct rate until its internal temp rises and allows for expansion inside. Cap that are critically high esr require a temp higher than their normal operating range and therefore always have the squiggly lines appear on the screen.
The caps in these are smd (surface mount) caps and are usually replaced using mini camcorder caps - bending both poles out vertically from the cap and trimming them to fit the platform. SMD's are so much more difficult to work with and I for one hate burning my fingers on a hot solder tip.
You can consider pulling the module and having it sent in for the repair as an option. On a scale of 1 to 10 and ten being the most difficult, this repair would be a 7...
Hope this helps.

Toshiba 57H82 problems


Val,
It's sent via Pando and you should get a link to it in your mail. To open it you'll need Pando, it's a free download if you don't already have it... The hyper module on that has about 10 caps that are common in that failure. If you need anything off board don't hesitate to ask.

The hyper module is located in the metal box just behind the panel where all your cables plug into the tv. It is sodered to the board syou have to get under neath and melt the four places that the metal box is sodered. Once it's out you can either replace the whole board if you can find one. I can't seem to find it anywhere. you can also chage out all the 16v 10uf capacitors which is generally the source of the problem, but even these seem to be very difficult to locate now too.
Toshiba doesn't carry them anymore. Here is a link to the bulletin they put out becuase those capacitors are a known problem and failure point.

If you locate the board for replacement on the net please post a reply to this thread i'm in search of. Thx.
