NORCENT PT -4233


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

Plasma TV color problem


Sometimes, poor picture quality occurs when having activated an A-VHS camera or camcorder connected and having connected another peripheral at the same time. In this case switch off one of the other peripherals. Also, The norcent has a known problem with progressive scan - when connected to a progressive scan source, it yields a distorted screen with dual images and messed up colors.
