Hello all, I have this Toshiba LCD giving me some troubles. Initially, upon pressing the power button it would refuse to turn on and instead blinked its little yellow light at me 3 times in succession. The service manual refers to this as "Seine Booting" where Seine seems to be the name of the main custom processor on the mainboard. Apparently this blink code means it is unable to boot for some reason.
I found a used replacement mainboard which was pulled from a working TV with a dead panel, or so they say, and with the new board the TV powers up, the backlight comes on, and these vertical stripes shown below slowly fade in for about 5 seconds before the set turns itself off. Then the yellow and green lights blink alternatively.
The service manual does not seem to reference an alternate yellow and green blink. Another thing, the service manual is trapped in Toshiba's crazy outdated "Zeus" service manual software so I'm running Windows XP in a virtual machine to view it properly. I can pull pages and diagrams if anyone needs them.
