Question about Toshiba 50HX81 50" Rear Projection Television

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 Phillips flat screen picture flips after being on about 10 minutes no flashing lights I switch the format and it straightened up for a minute but started back flipping can you help me assess this...

Vertical 'flipping' is almost unheard of with modern digital video. Are you receiving your signal via the coax antenna or cable input? You might try using a different input method and possibly a different source (DVD player etc.) to see if the problem is consistent. You might also check the refresh rate of the TV and try changing it. If the problem only happens after the TV warms up, you may have a heat related electronic problem with the TV. Try blowing a fan on the TV too see if this delays the problem for 5 minutes or so.... If it's heat related, it will likely be an expensive repair unless it's under warranty.

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.

My CRT TV displays a single horizontal white line across the screen. It will flicker and try to display the picture. If you smack it you'll get a quick picture then back to a line. After about 10-15...

The single line means that the vertical deflection doesn't work. And since it is working when you kick the tv or has warmed it's clearly a bad connection - open the case and reseat the wires going to the tube coil.

Picture won't come in clear until TV "warms up" for 15 minutes or more

Change the capacitors first per the instructions in the link below. Symptoms could be anything from high-pitched hum to no picture at all. On these defective models, I would start at the caps and work back. It won't hurt to replace them anyway.
