Re: Samsung UN65KU6300FXZA no picture
Not having any luck finding data sheets or schematics. The EEPROM Shopjimmy is selling is in location IC1104 and the ebay site says "The T-CON is built into this board". So i am guessing that this eeprom is part of the T-Con circuitry? Just wish i could test it to see if it is indeed bad.

Re: Samsung UN65KU6300FXZA no picture
i did see on SHOPJIMMY.COM they were sell a kit for the main board but are sold out and also selling EEPROM's, not sure if that is the problem with mine but i guess it's worth a try.Leave a comment:

Re: Samsung UN65KU6300FXZA no picture
yes the 13v is steady, i couldn't tell if the AVDD says 1.7v or 17v on the board but i have seen flashes of up to 16v and OL.Leave a comment:

Re: Samsung UN65KU6300FXZA no picture
with the LVDS disconnected at the MB, backlight comes on bright then dims then off, red optical led comes on at power on and stays on for a bit after the tv powers off then goes out, tv powers back on and repeats.Leave a comment:

Re: Samsung UN65KU6300FXZA no picture
ok after a 2nd check i realized i had VM set on ACv, on DCv i get 12.66v on the power supply with the cable connected to the MB but it drops to 9.4v and shoots back to 12.66v right before the lights come on. i get 3.3v at panel check point but the AVDD is all over the place, seems to be at 2.0mV and goes up but nowhere near the 1.7v it should get with everything hooked up.Leave a comment:

Re: Samsung UN65KU6300FXZA no picture
Hope these pics work better, the 1st 2 pics are of the 2 testing points i could find on the main board. The next 4 pics are the main board in 4 sections. The next 3 are pics of the screen, 1st pic is with uconnectors in place, 2nd is with the left u connector out and the right side in place. 3rd pic is left u connector in place and right u connector out. The only difference i could see is no matter which u connector was out the horizontal lines on the bottom where gone....Leave a comment:

Re: Samsung UN65KU6300FXZA no picture
Budm I get nothing but a blue screen that flashes bright then dim then off then repeat. Disregard post 10 if you will, I tried getting some voltages but they are all over the place in accordance with the screen flashing on and off. The only stable voltage I can get is the Panel-3.3v on the main board test point and the 12.66v coming off the power supply but only if I disconnect the cable that connects to the main board, with the cable connected the reading is all over the place for the 12.66v.Leave a comment:

Re: Samsung UN65KU6300FXZA no picture
neilc6 I have a 60" Vizio that I put new backlights in but while I had the screen set aside my cat decided to chew on one of the side ribbons, when I put it together that side of the screen was white and it had horizontal lines across the screen parallel with the damaged ribbon. I thought it was a goner but Budm suggested to peel the ribbons off on the side that was damaged and it was like rising from the dead, it worked. I was so excited that when I put it all back together I didn't make sure the screen was sitting in it grooves when I...Leave a comment:
