Hi all
This toshiba 32hl66 came in with no backlight but sound. When we did a precheck, it was totally dead.
Further checking shows a blown fuse and shorted transistors on one half of the inverter board. Replaced the inverter board but still a dead set.
Thanks to Retired Caps was able to get a schematic which was very helpful. The set will start to boot up when the power plug is plugged in and then a brief booting up occurs and the set will shut down......... Tying to push the power button does not do anything.. Will have to unplug for about three minutes before trying again.
We have the power plug into a current meter set up to see what the current flow is and there is absolutely no activity on the meter when the power button is pressed.
Is it possible and likely that the shorted transistors and blown fuse ultimately hurt the power supply board??
Any other ideas or directions to take would be appreciated...
Thanks
Bill
