Your Model # is probably 50H81, or something like that. Without the
model, or chassis number, it's hard to tell what part number is the
right one, but it sounds right about the "hyper module" being bad, &
it costs the repairshop about $ 300 approx. to get it rebuilt at
Toshiba. Also, the module is not available from Toshiba, & has to go
to Toshiba for rebuild to guarantee a proper rebuild. Some techs do it
themselves. The hyper module is listed at the site below, but they may
not have stock. It is a good T.V., & they DON'T make them like they
used to. If the picture isn't blurry, or weak (bad picture tubes), it
IS worth repairing. These units last a long while. You could try
ptscorp, they had stock a while back for $190
&you can get $60 back for sending them the dud. Below is their site.
Hope this helps you out! Dani.
