I searched "pola2.0 60" on ebay and got lots of matches. I also searched "2835 1W 3V LED" and got lots of matches as well.

Usually when I recommend full strip replacement, the typical response is...

Re: LG 60" 3d TV LG60LA6200UA Screws and LED Beads

If you want your repair to last, I would replace all the LEDs with new strips. The working ones will likely fail in the future since they have wear. There are two styles of the LG thick lens...

Re: Samsung LE37B530P7W 37" dead power supply

Blown fuses will always be caused by shorted component usually FETs and diodes. You should be able to measure the short on the component side of the fuse to ground.

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: 60" LG 3D White Reflector Sheet

I did one of these 60LN series and never again because of the glued down sheet. I would cut the strips out with a knife.

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: ANOTHER Vizio M65-C1 No picture Issue

Your replacement board is bad as well. ON/OFF comes directly from the processor.

One good thing about buying boards from ebay is the money back guarantee.

Re: 6V or 3V LED??

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

PS_ON is active high with a pull up resistor. Shorting it turns it off.

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: Samsung UN40NU7100FXZA....MELTDOWN!

Re: Sceptre X505BV - Logo appears for 1 sec then backlight shuts off, LEDs tested goo

Your LED tester only puts out about 20mA while your TV runs at a couple hundred mA. You have intermittent LEDs in the string. Their voltages will be higher or lower or they may be slow to turn on. ...

Replace all the strips with new and turn down the backlight level. All the LEDs have wear and the working ones will likely fail

Re: Samsung Un60es6100 LED how to force power supply on?

Samsung TV power supplies typically have pull up resistors on the PS-ON and BL-ON control signals so you just need to disconnect the cable going to the main board.
