Samsung LN52A550P3F ...... Vertical Lines/Black Screen

[Paul678]

The sound is fine on this one.

But the owner cannot see the menu, because the
screen is either random colored vertical lines, or a black
screen. When it's a black screen, he can still see the
backlight lamp illuminated.

He thought it was the T-con board, but after
replacing it, the problem was still there.

Ideas on this one? Thanks for your time.....

It was the T-con board on a 40" Samsung I had that caused this problem. A voltage regulator on it failed. It's possible he received a faulty T-con.

The remaining candidates are the main board and power supply. Or a loose T-con connector.

I would go for it - sounds like an easy fix. Even if you bought both boards, that's going to be cheaper than a new 52" LCD. But don't pay more than $50.

Actually, this is a repair job. He's not selling it.

I seem to remember you said you don't do repairs for other people.

But if you did, what would you charge for the labor? Excluding
the cost of boards you may have to order....

After my last TV job, I understand why the repair guys
charge so much.....

Well, it would take me around 2 hours, £60/hour... plus tax and parts etc.

I'd make more money repairing TVs myself to sell, that's why I don't repair them.

Yes, that's become quite clear to me now.

Problem is, I have a Honda Accord, which barely fit a 46"
in the back seat last time, so I have doubts about moving
a 52".....maybe time to call a friend with a truck.... hehe
