Question about Toshiba 57H81 57" Rear Projection Television
When TV is first turned on there appears to be an instability in the horozonal, after 20 minutes or so(time keeps grtting longer), it settles down and picture is normal. If we leave the TV on, problem never appears. If you turn it off, even for 5 minutes, the instability appears and it takes 20 minutes to settle down. TV is 4 years old. Please help? What PC board or module will I have to replace? Thanks, Ed Wilson firstname.lastname@example.org
Hello Super Guru,
I have Toshiba 43VJ22P for 3 years. Now I can only see pixels for first 20 minutes, after that I can see some hazy pictures on screen only. What is the solution. Your smart ideas will be highly appreciated

I had a estimate to repair the Hyper board. The cost is between $350 and 500.

I have a Toshiba Modle 57h81. When you turn the TV on it automaticly goes to shut down mode. I've already check the fuses which are all okay. As well as changed out the convergence ic's. The problem continues to remain. Can anyone help me?

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
