Is the samsung panel s42ax-yb01 and s42ax-yb04 interchangeable?
I have a Dynex DX-PDP42-09 with the Samsung S42AX-YB04 screen that is busted and would like to know if a S42AX-YB01 screen in a Philips 42PF5321D/37 that has other issues would interchange?

Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
If you go to www.encompassparts.com and click on guest log in and do a part number search with the numbers you have listed, except use LJ41-02761A, and it will give you the cost and such.
I have the same issue. I'm looking for the power supply schematic. Some components are dead (like U501 and ZD501). I'm looking for the reference of the zener. Does any body have the schematic or the part list of the board (ref PSPF501B01A) ?
Sounds like your having problems with your Y-main(upper buffer) is getting too hot. The IC's located on this board are really bad about going out a lot. If you take the back cover off your Plasma. U will see that the manufacture of the panel is Samsung and the panel model is probably S42AX-YB01. you should be able to purchase the board. probably will run about $ 150.00.
Hope this helps
it unusual to have the screen go faulty itself. With plasma screens what goes is a power transistor, and there are 3 or 4 of these on one of the circuit boards. The likely board is the one with the big heat sinks as the power has to be stepped down to a lower voltage before it can be used properly. It is best if you replace all of the power transistors as one may have affected the other. If you are no good with a soldering iron then either get someone else to do it or replace the whole Circuit Board (PCB). Beware there are plenty of people aching to make a quick buck out of people who have no knowledge on this technology. If you want someone else to do this for you then find someone honest. A telltale sign for the power transistors is that they sound a pop when they go faulty. A symptom is a blank screen sometimes showing on standby mode. I would say your screen itself is ok, so sell it on to someone who needs to replace a physically damaged/smashed one if you no longer need it.
