Picked up this TV yesterday. Original owner said screen went out. Rather vague but OK as long as I didn't see any cracks I said why not. Only 40 bucks. My 65 cost 2300 new! It's a 55" version of the 65" and I've had for 3 years running strong up on the wall.
When turned on right side black left side white with faint vertical stripes.
My 1st rule of measure was to pull all covers off to expose LCD source driver boards on the panel itself.
This is after trying one ribbon at a time trick. Left side would show a faint picture right side remained black.
Checked MLCC capacitors and found right side shorted. Look for the lowest resistance reading in found one reading .7 Ω where the others are reading 1.8 Ω. So I went ahead and removed it knowing that all these capacitors work in series. The bad capacitor was the 1st one nearest the ribbons that go into the source board from the tcon.
Powered up and have perfect picture!
Removal pics to come as soon as I can find my USB cord.
