Toshiba hyper module. Vertical lines on screen.

change the 10 or so surface mounted bad filter caps in the Hyper module this set uses--the board is no longer available--it can be sent out for rebuild (not toshiba) but that is rather costly (200+)

Toshiba 57h81 location of vidio baord

yes they are bad, they are surface mount on the digital board. Board replacement is advised. They are not easy to change if trying to replace the capacitors.

Toshiba 57h81 location of hyper board and remove procedure

Hyper board is located directly behind the input board, this is where all the tv conections are, then they are two tabs soldered from the bottom of the board then it simply unplugs, But replacing all those capacitors on that board can be a little tricky, replace all 10up @16volt caps and that usaly repairs the board

Toshiba 57H81 picture bounces. Can't tell if horiz. or vertical.

Unstable picture, wavy, jittery, and loss of sync are a symptom of bad capacitors in the hyper module. The problem is worse when the set is cold, but when warm the sympton gets less or goes away. In the latter stages the problem never gets better even after the set has been on for hours. There are about 6 surface mounted caps (10mf/16) inside the shielded Hyper module. The module is vertically mounted behind the jack panel and can be unplugged from its socket after unsoldering the 4 anchor tabs on the bottom side of the PCB. This type of repair should be made by a qualified technician do to the complexity of chassis removal and expert soldering skills.

Toshiba 57H81 Image issues!

I am thinking surface mount caps on the Hyper board. That should definately be serviced by someone experienced with Toshiba Hyper boards.

If you have zagged lines there are 10 small surface mounted capacitors you will need to change on the HYper Board. This is not an easy repair so alot of folks simply replace the hyper board. You will need a service manual to take this set apart and to get the proper part number. If you have no TV repair experience or do not know how to solder, as the hyper board has sheild arounfd it, you should play it safe and call out a pro to assist you in this repair. Good Luck

Toshiba 57H81Problems Please Help

On this model I've found the hyper module to cause lines (Left to right) in the picture. Usually at start up and half the screen, then after warm up, the set will clear up some or completely. Of course a picture of the problem would help in diagnostics. The hyper module must be soldered in, so, knowledge of soldering is advised. This PCB can be bought at: Andrews Electroncis or Tritronics. I do this job in the home, pick up for service should not be required.
