LG 42PQ10-UB - no picture (videos inside)

[kenzo42]

Hi,

I have the LG plasma 42PQ10-UB. It doesn't display a picture, but there's still sound. I took off the back cover and didn't see any bulging caps.



I see a green blinking light in the back (seems like morse code):

And lastly, this is me turning on the tv. It makes a loud click noise when turning on. I could have swore it stayed red, but now stays blue:

Any ideas what could be the culprit?

Thanks.

Is the screen glowing slightly when turned on, or is that my imagination?

Definitely no glow. Just triple checked it in complete darkness.

OK. Do you have a digital multimeter available?

(1) Check VS and VA voltages on the power supply.
(2) Check VSC and -Vy voltages on the Y-Sus.
(3) Check Vzb voltage on the Z-Sus.

Compare your readings to your panel spec voltages. Post a pic of the panel label with voltage specs if you're unsure.
