Akai 50 inch plasma t.v popping started, now t.v don't work
Hey guys I have a Akai model number is PDP5016h. One day in december last year which was close to christmas. T.v was off but connected and we
heard some loud popping sound like loud as a bullet as if u
heard it from outside while inside. Anyways now, when you turn it on
it is black yet you can burly see movement. I checked inside the plasma
t.v and everything looks great and brandnew except the power supply.
One part, on a pin it is rusted, or look like it is rusted. And there is also
dried white stuff. It just doesn't look normal since I fix computers. Can it be that that went wrong? It is so hard to find parts for this things. Can somebody tell me if I am right? And also where can i get the part from?? Thanks

See I cant cross that part number and I have all the boards sitting in front of me. That number is the akai part number, but not the actual number of the board. There are 2 boards that they call main in the service manual, the main control board which actually drives the panal, and the "main video board" which handels the video inputs and on screen displays.
PCB failure analysis 1. MAIN CONTROL : a. Abnormal noise on screen. b. No picture. 2. MAIN (video): a. Lacking color, Bad color scale. b. No voice. c. No picture but with signals output, OSD
and back light.
If you can determine which of the 2 boards is the problem, I can sell you a new replacement for $125 shipped.
Basicall....Control board is no picture at all.
Main board is no picture, but on screen displays work.
Thats a real tough call on your problem as the set acts like its working normal and then gives out. It could be any number of things, but mostlikely somthing is drawing too much power causing a protection fault hence the power off. These types of problems are very hard to diagnose as the stuff your looking at looks good, its not until it warms up (even being a few seconds or so) that they go bad. You can allways put a meter on the VA and VS to see if there is a flucuation in voltage or even a spike and that could tell you possibly which board is the culpret, but the best is to replace and not repair as switching supplys can be a pain.
It may be your serviceer does not know where to look for the parts. Akai is made by many different manufacturers and the parts for each manufacturer come from different distributors. I beleive your model is supported by Vance Baldwin
