After checking U14 (EEPROM) and finding it OK, I put the main PCB on my hot plate at 350* for about 10 min to reflow U11. Put board back in and TV fired right up! Go figure!!!! ...
Have a Vizio VL470M, Upon plug in, VIZIO light is yellow, no response from on button on TV. All voltages coming out of PS are good. All voltage checks on Main out are good except "inv" on is 0v. (orange wire). Any ideas?
Just received a Samsung UN40JU6500F and after turning on, it has a 5 blink code. After taking back cover off, found that one of the ribbon cables that is attached to the LCD panel (permanent ones) was torn. After disconnecting T-con PCB from panel, the LED backlights fired up. Anyone else seen this 5 blink code on this model?
If you have a "14" blink issue and have replaced some of the FET's, Check "Q600" before firing up TV. I've fixed over 50 of these boards (TNPA5351) and on about half of them that MOSFET was bad. If it is bad and you start the TV, the FET's will blow again.
