Open Question

Norcent 42 inch PM 4203

No picture. For awhile it worked when you tapped it on the lower left hand corner...has been getting progressively worse, sometimes you can't get picture at all, just black screen. It seems like something's just a tad loose or poor connection somewhere.

I had the same problem too. It called the Y-main Board. It cost $145 if you order directly from Norcent itself. I hope that help.

You may have lost the 24vdc due to bad caps, this 24vdc is used to power the backlight inverter baord, or you may have failed inverter board. Look for 24vdc first.

Norcent Technologies PM-4201 42 in. EDTV-Ready Plasma Television that turns itself off within one second. Then the remotes don't work and I have to unplug the tv. Is the tv shot?

Sounds like the main power regulator board inside the TV is faulty. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

It's likely the upper Y-module but both the upper and lower could be having problems - just nothing noticeable in the lower half of the screen as yet, is my guess..
This is not a job for a layman and you'll need some fairly sophisticated equipment to troubleshoot the boards, not to mention being able to read schematics and understand waveforms. Hence, my best advice would be to take it in to a reputable shop and have it estimated...
