Hi Ive had my recorder for a couple of years now, but yesterday when I switched it on the picture was really really bad - it was all liney and jumpy. From the minute I switched the machine on, the blue screen that says toshiba was even liney and jumpy. My TV is working fine. Any ideas about what could be wrong or how to fix? Thanks!!

Hello MagillaG, You are getting off cheap considering that this hum may be from the IHVT, hopefully the hum is not for that component. Since you have no picture and no sound that denotes a power supply probme which can be anything from a blown fuse to a bad IHVT or the horizontal output transistor. $180.00 is about right.

I am working on the exact same problem with the same symptoms. Make sure the tv is unplgged for at least 5 minutes before poking around. The power cord can be unplugged from the power board and removed to keep anyone from plugging it in while you are working on it.
The STK's are the large 18 pin integrated circuits (chips) mounted to the large heat sink on the convergence board. This is the board on the right when viewed from the back of the TV.
The resistors are beneath the heat sink on the left side of the board. There are also fusible resistors, like #7711, on that side. There are NO pico fuses in this area.
Fuse 853 is on the Power board. This is the board on the left when viewed from the back of the TV. You can remove both boards in the carrier by carefully unplugging all connectors, noting their locations and routing.
To remove the high voltage wires from the splitter, mark them for position then grasp the boot and turn counter-clockwise about 10 degrees to unlock them and then pull up while holding the High voltage splitter. The small high voltage wire can be removed from the flyback transformer by pulling hard while holding the flyback.
STK392-110 can be replaced with STK392-120, STK392-180, STK394-160.
I have found most of the parts at newark.com. Also check out this site for some very good info: http://www.hometheatershack.com/forums/diy-repair-maintenance/5600-crt-based-rptv-convergence-repairs.html
btw: I am not affiliated in any way.
Make sure that while you have the boards out you look for any bad solder connections. A lot of problems arise or return because of this.
I hope this helps, I have been doing a lot of searching to get this info and hope it helps you. Too many people want to trickle the info and pretend they are giving you gold. A few hobbyists or people that can't afford to pay $300+ for repairs are not going to hurt their business.
Be safe and share knowlege freely!

SOURCE: TOSHIBA 57H82 TV Blurry for 15 minutes till warms up

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:
Part Number23148024


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.
