Question about Toshiba 50HX81 50" Rear Projection Television

1 Answer

Help! Squilly lines

Squilly lines through out the picture... it use to be that after 15 - 20 minutes of warming up the picture would straighten out. Needless to say That is no longer the case....From my research here, some say it is the hyper board. Is this something that I can purchase and install my self? If not what is the 'going rate" to have this type of repair done?

My Toshiba 53HX71 takes about 20 minutes to "warm"

This is a symptom of poor solder connections inside the set. The set will continue to deteriorate until it won't turn on at all. This is essentially a labor only repair and should not be to expensive for any TV service shop. Once this has been repaired, the set should work for many years to come.

These poor connections are caused by the continual heat/cool cycles because of use and is normal.

My Toshiba 42H83 has a scrambled screen for about 5 minutes when it is turned on, if it has been off for a while. Once it warms up, it works fine. I have replaced the satellite receiver but this did not...

ok, you are talking about lines in the picture, it started where it would clear up after a few minutes but now it will slowly take longer?

I know what is wrong.

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.
