Re: toshiba 37x3030D power up issue

Hi guys!

I got the tv working by changing the Signal board PE0251, the one with the big BGA on it. Now I got another problem...either the new signal board is defective or the t-con or...the panel.
The tv starts and lights up ok, but the image is doubled, it`s rolling horizontal and the menu is all messed up. All the letters are scrambled, I can read it but it`s hard.
I`ll post a video...
If i go into service menu and change the screen size from 42" to 37" or 32" the menu screen changes to better...

The service manual needs DWF viewer and internet explorer.
I`ts in the attachment. Thanks!...

Re: toshiba 37x3030D power up issue

I have the service manual...the signal comes from OCS memory. The 2.8V POWER PROTECT comes from the ST_BY CPU. I`m not sure what triggers that POWER PROTECT, that is why i`m asking you help, maybe you remember what was the problem.

Thank you...

Re: toshiba 37x3030D power up issue

Mr_Bodgit can you tell me what was the problem with the 12V line?
My TV has the exact same problem...no VCC_LCD voltage, the regulator does not start due to no signal from the POWER_LCD input and the POWER_PROTECT line stays at 2.8V.
All the other voltages seem to be there.

Thank you!
