Norcent PT4233 no picture, black screen, but has sound. How to repair

The display (PDP - Plasma Display Panel) at the heart of this unit is a LG 42V7 model. There is a known bad solder "defect" on the YSUS board that causes this board to fall unexpectedly.

The bad news is that you have to replace all the primary boards on the display - ZSUS, YSUS and CTRL boards, as the failure can/often takes them all out.

The good news is that LG makes a repair kit for this panel. Its part number is 687VSNB03E and it contains the three boards LG6871QYH036D (Y SUSTAIN), LG6871QZH041B (Z SUSTAIN) and LG6871QCH053G (CTRL).

Hope this helps

Sounds like a cap or fuse has blown in the set, you will need to take the back cover of and have a look, check on the power board for any blown caps, you will notice them straight away if one has poped, also check any fuses that may have blown they will also need to be replaced.

Sounds like it could be a problem with high voltage stages. Definitely a job for a TV technician as it is dangerous try to repair it yourself.

Black screen but have sound


If it is not a hardware problem, it is most likely the Closed Captioning system.
If you can still see the on-screen menu, go into your TV's menus and disable Closed Captioning.
