Re: Yet Another TC-P55GT30 7 Blinking Light Error



I do have the ribbon cable. Simply took it off to make it easier testing. Now are you suggesting that I short SC50? What would the purpose be?...

Re: Yet Another TC-P55GT30 7 Blinking Light Error

Tested everything I could with a multimeter and my dad's help since I don't know how to configure a multimeter myself. We were reading for Ohms and everything that we measured was an open circuit, as my dad said, and was not shorted - all the pins we tested read 1 on the multimeter with a few exceptions.

The few exceptions were one corresponding pin on each ribbon connector on the SU and SD boards. The other exception was one pin on the white connector going from the SC board to (I think) the SU board.

Hey everyone! Just picked this TV up for $25 off of Craigslist to fix and give to my fiance in her new apartment.

I am not getting 12v on both sides. I forget my reading but it definitely was not 12v.

Alright so to keep this brief, I have an LG 47LV5500 that when turned on, has a picture with many vertical grey lines. You could faintly see the LG logo and such in the background. It has sound. I followed [URL="https://www.badcaps.net/forum/showthread.php?t=36324&highlight=47lv5500"]this link[/URL] and played around with the T-Con board and disconnected all the cables and reconnected them. After doing that, the screen now has a completely black picture. The backlight still works and everything but there are no grey lines - just a black screen.

I figured this means...
