Toshiba likes to solder shields / covers in place.......check..
Small boards have a side clip = release with screwdriver while
releasing end clips = hard to describe, best to visually inspect.
I will let you know about service literature = CD ROM.........T.

SOURCE: 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

I have vertical lines on my screen. They appear to


This a common problem in many of the Toshiba sets----set has a "HYPER" circuit board that processes all the signal for the set--surface mounted caps all start to dry out--always starts out where it will have the problem and then when on for a while it gets better and goes away--eventually when enough of the caps are gone--it never gets better.

Board is now only available by removing it and sending it out for rebuild/repair---company doining this is Pts electronics--part number is:

23148103Cost is about 180 dollars plus shipping and this may mean considering the labor to get the board out that the set is not worth repairing.


Sorry to give you bad news but I am certain this is what your trouble is.

When I first turn on my TV, I get horizonal faded lines


it probably has leaky capacitors in the hyper board or the video process board, this repair requires a qualified tv repairman, you can't do it yourself, alot of actual repairman can't handle this repair. it will get progressively worse as time goes on the more leaky the capacitors become.

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
