Question about Toshiba 55H70 55" Rear Projection Television

1 Answer

Toshiba 55" 55H70 model. Turns OFF, but won't turn ON until I unplug it from the wall first.

Toshiba 55" rear-projection TV Cinema Series - HDTV (1080i, 480p)compatible Model: 55H70. Bought it in March 2001. Problem: If I turn OFF the TV via the remote control or pushing the ON/OFF button. It will turn OFF. But when I go to turn it back ON, the red power light on the front just blinks. So I have to unplug it from the wall and plug it back in...then I can push the ON/OFF switch to turn it ON. Can you give me your opinion on what is wrong?

    Here's a resolution that I received.  I have not done the repairs yet.  So I'm still unplugging it to turn it ON.



    **************************************************************************

    It sounds like your convergence IC's are going out.

    This is a common problem. There are two IC'c that control multiple functions and they are a high failure part due to running hot. There are also some resistors in that same circuit that will sometimes overheat and change values. The only other thing it may be is a yoke going bad, which is a copper coil that fits over the tubes. I've seen two yokes go bad compared to 100's of convergence IC's so its more than likely the IC's. You could wait until it completely quits working, or you could fix it now, but it will only get worse. You are not really doing any damage by playing it like you are, its just an inconvenience. The total cost to repair the convergence circuit would be $225, and if it was a yoke it would be $25 more. I have all the parts in stock so if you decide to fix it let me know and we'll schedule a time. Thanks for your inquiry.

You will need to trouble shoot the start up and shutdown circuits. Often this is a minor component failing causing the set to not power up or go into protective shutdown. Do you have the service manual for this TV?

my thought is that it's something with the closed captioning, fiddle with those settings in the menu, or with the devices like VCR or DVD if you're using something like that as a tuner.
