Question about Televison & Video
Blows the fuse on the power supply board every time I unplug it from the wall. It plays fine and stays on and shuts off normal but when I unplug it blows the fuse.
Ensure u use the right fuse rating ask ya dealer ya fuse may be less than 13 amps hence heats up n melts

You need to replace the outlet your plugging it into or go to a different ciruit in the house n try again.

try a diffenrt outlet if it still bunrs of a different fuse! could be the fuse not big enough for the different appliance on the circuit !
i would suggest take it to a tech it could be a problem in the tv that could cost only a few $ to fix !!!!
against trying to much to plug it in and out you could burn transistors or other expensive part of the tv!

If the fuse blows again after replacing it, there's a shorted diode, bridge rectifier, capacitor or transistor in the power supply.

good day. your power supply is defective. maybe the regulator is shorted. you need a qualified technician to fix your problem.

You can do this by yourself all you have to do is to open the back cover of the television to check the faulty components. to fix you must have basic knowledge on electronics .
The fuses are there to protect the set from catching on fire in case there's a short circuit inside the set. Now in some cases an intermittent short can work after you replace the fuse but if its burnt black or brownish, there's a circuit inside the set in one of the circuits. always use a 100 watt light bulb across a blown fuse if your not sure if there is a short. if there is, the light will absorb the short and glow bright. if there is no short the bulb will glow bright , then go down very dim. you could have a main power supply problem, such as shorted bridge rectifiers,shorted main b+ capacitor, Hot could be shorted, or the Vertical or audio output IC could be shorted.
I hope this help in solving the problem.....

SOURCE: Hi my pxt-50xd1 plasma
i have 2 of the power boards now i am struggling with, but there's a small capacitor that has gone on both of mine, it's labelled c5017 and is 10pF according to the service manual and i cannot remember the voltage but i'm using 630V ones to be safe but i think the orginal is much lower, so best to test that cap to see if it's causing the problem
