This model uses a "HYPER" BOARD to process all signal from all inputs.

These sets have a history of tiny surface mounted capacitors on that board failing with age---they dry out inside.

Usually it will clear up as the caps get hot but over time it will take longer and longer to clear up.

The board is no longer available from Toshiba and the only way to fix is remove the board and send it out for rebuild---last one I did cost over 200 for the rebuild.

I have had a few on this site with this problem who were able to do the repair themselves, it involves getting the board out and real skill at soldering.

If this told you something you did not know, rate this solution as very helpful as I do this here for free.

    Thank you and I am happy to get a quick response. The answer says, "remove the board and send it out for rebuild".
    the question is i) how to identify this tiny surface mounted capacitors on the board or the exact location of this board in the tv ii) "WHERE ' to send the Tiny surface out for rebuild. My zip is 75094 if it helps you to suggest. Thanks

    Experts here receive credit for very helpful, not somewhat helpful----2 thumbs up is not a good rating.

    I can tell you where to send the board and where it is in the set.

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+)

Red color convergence on Toshiba 57H81


Often convergence issues do not require the entire board to be replaced. You can resolve it by replacing the convergence ICs. The part in question is STK392-110. You will need two of them and they cost around 10$ each. But replacing them is a pretty complicated procedure and I would not suggest it to someone without prior experience. A service manual should get you started in the right direction if you are planning to do this yourself.

PS
: Disconnect from the power supply before you start the repair. Also read the legend, the hv circuits are denoted by a special symbol, so you will know what you shouldn't touch.

You may also need to replace the nearby resistors that may have popped the IC in the first place. Read the service manual for further details.

Good luck,
Sai.

Toshiba 57h81 red light blinking


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Is my Toshiba 57H81 worth repair?


Bounce horizontally usually means up and down,which relates

to the vertical output IC. Solder IC301, IC401 pin connects==try

again.You can easily isolate "bounce" problems by lightly

tapping on the vertical IC heatsink....Let me know if you need

further assistance.....T.

 

PS. Though hard to find, a qualified tech could do that repair

in home for 300. to 400.00...

Toshiba model 57H81


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
