Re: Toshiba 49L621U - Backlight protection shutdown

C[SIZE="5"]Hi, it sounds like one bank of light is open. This model set usually has 3 banks of light. If any bank is open, you will get a momentary flash of light and then the set shuts down. [/SIZE]Re: Toshiba 49L621U - Backlight protection shutdown

Re: Samsung LN40D550 Power supply short circuit

Does anyone have the Power Supply schematic for the model LN40D550 LCD TV? If yes, will you kindly post it on this thread.

I had a similar problem of the Power Supply on this Samsung LED TV recycling on and off where you can hear the main relay clicking on and off

After extensive tracing and diagnosing (and lots of luck----I did not have a schematic to work with) I found that if you ground the collector tab of D9052 to COLD Ground, the cycling will cease and a normal operation is restored....
