Re: No power on Vizio D32F-E1 TV
Looks like no separate PS-ON signal and power supply is always on at 12V. ON/OFF is backlight on signal. If you have stable voltages and the TV is dead, main board is suspect.

Re: 60" LG 3D White Reflector Sheet
I would score along the strip and heat up the double sided tape under the strips. The thick lens strips use extra sticky glue. Without softening the tape, you would need a scraper and hammer.

Re: ANOTHER Vizio M65-C1 No picture Issue
I purchased a guaranteed working and tested board with the same failure previously. If sellers takes returns, then easy for an unscrupulous buyer to return a bad board and it gets resold.

Re: 6V or 3V LED??
For models that have protection shutdown due to shorted LEDs, the voltage needs to be correct (LG, RCA, Insignia). Samsung designs dont have shutdown and you end up with most LEDs shorted and...

Re: Samsung UN55JU7500F
I believe 9.2V is the standby voltage and gets boosted to 13V when turned on. Power supply is behaving as expected.

Re: Samsung UN55JU7500F
If the standby voltages are stable and PS-ON signal is stable, main board is suspect if TV doesn't turn on.

Re: Toshiba 58L1350UC LED Flicker
This model (and Toshibas in general) is a nightmare since bad LEDs can damage the controller IC on the power supply and vice versa. I ended up buying a new set of strips and the bad controller...

Re: TCL u55p6006 no backlight
Replace all the strips with new and turn down the backlight level. All the LEDs have wear and the working ones will likely fail
