42LG3000 LG Television

[Berts]

Greetings,

I am new here so would just like to say hi.

Please could someone offer some advice on a LG 42LG3000.

I usually fix computers so this is a first for me.

The TV powers on fine, back-lights are good. A picture can be seen but unfortunately it jumps all over the place but only on the vertical axis.

I have googled around and found white screen / black screen problems, but nothing on this flickering and jumping picture.

Any ideas? I will of course try and help some people in the computer section so you know I am not just a newbie freeloader!

Thanks in advance for any ideas / advice.

Bert

I would guess a noisy voltage regulator. I have a TV right now giving the same issue and it is a voltage regulator which is oscillating due to bad capacitors near it.

Hi,

thanks for replying.

Would you suggest replacing the power board?

I cannot see any signs of bloated capacitors.

No, check the main board first. Post pictures.
