Re: UMC 32/188G Distorted Picture/Scanning Loop



TV is back up and running. Turned out to be the GPU on the main. Bought a second hand main from a different model tv and replaced the BIOS IC with the original. I upgraded the heat sink also. All good again. Thanks Flocko.
Picked up a Toshiba combi from the dump for another challenge. Flashing led, squeaking noise.. I'm suspecting caps ...

Re: UMC 32/188G Distorted Picture/Scanning Loop

So, the eeprom arrived from ohms supplies. After replacing it, the TV went to standby as normal and the back light booted up after pressing the pwr button.
Nothing else though.
The screen is blank. No other input works, menu, ch +, etc.
The IC stamp is different on the BIOS replacement chip even though the replacement web pg states its for 32/188g-gb-5b-tcu-uk.
Should I have specified flashing the BIOS as per board type?
Any thoughts?
Tom66, you mentioned reading the .bin files, is this easily...

I have the exact same problem and have just ordered an eeprom from ohms supplies. Thanks flocko!
