Looking at picking up a 3D TV SONY 65" 4K - XBR-65X900A for $20 and was wondering if it's worth the trouble. It has horizontal lines on the top 1/3 of the TV. Is it fixable?
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: SONY 65" 4K - Horizontal Line on top
do the test of one ribbon disconnected at one time.. and call the menu setting... let see how its look.
EDIT: before you start with the test i mentioned above.. you need to take out all ribbon cable out and the LVDS too. inspect them under good magnifier from end to end, you may find damage at the pins contact.Last edited by Diah; 11-28-2020, 01:15 AM.

Sorry the damage is 100% panel, unfortunately you have a combination of vertical and horizontal issues so this means bad source and gate drivers, for the vertical bars maybe there a corrosion on board for liquid spill, but i'm not sure since this has not to do with horizontal problem that seems of electrical surge, but if the liquid spilled also at the bevels maybe has ruined the gate drivers, i think 99% is unfixable, but 20$ is so low price, sell the boards..

i wrote inspect the ribbon cable contact pins under good magnifier if one damage or short or moved to aside..
if they are all fine--- disconnect the LVDS the small one and turn on ( call menu always at any test ).. let see what will show to you

Hey! this is a very good new, maybe the liquid is still liquid and does produces momentary defects not destructive, time to dismantle the screen bezel before the corrosion takes place...Last edited by Diah; 11-28-2020, 11:12 AM.
