When I was in the service mode I may have accidently changed a setting. Now the tv will Not show a picture. Is there a away to reset to factory specs? Thanks!

You can usually do it by connecting two pins on the EEPROM together. This will require you disassemble the TV though.

Can you be more specific on the eeprom location, I'm assuming its on the main board? Which two pins? THANKS! Board is PE0541

Yes, it's on the main board. If you get the TV apart take pictures of the main board. It's an 8 legged SMD chip.

Do you have a higher resolution picture... it's difficult to make out anything.

Re: Toshiba 42rv530u firmware

Is there a particular part of the board you would a better picture of?

Bought a supposedly new board. Still doesn't work. Now my 24 volt bus is gone. My twelve volt bus flashes from 6 to 12 volts? There's two led's on the board. They flash with the voltage changes. Ones green ones yellow.

Put the old board back in. Now my 24 volt bus is back. One steady green led on the board. 12 volt bus back at p811a.

Re: Toshiba 42rv530u firmware

Sorry your pictures are not much use. Too small.

Please try and get them as near to but not bigger than 2mb 2000*2000
and a better one of the whole board please.

If you click on them as soon as uploaded you can tell if they are any good then you can delete and re upload as an edit.

Pics can usually be resized in "Paint" or "microsoft office picture manager"
or something similar. I have been looking for schematic but have only come up with this.

This is what I have been working from. Thanks though! A power supply schematic would be very helpful.
