Question about Philips 42PF9630A 42 in. Plasma Television

Philips 42" plasma model pf5521d

Last week the tv made a loud bang whilst turned on and then no power/ screen/ sound. it is not possible to turn it on from the on off switch at the side. It is 1 year and three weeks old and therfore out of warranty according to the retailer. I will be dealing with them but can anyone suggest why it would suddenly do this after a year's trouble free viewing ?

    Prior to it blowing up was it making any strange noises the week before. Like a whistling or whining on turning it on or was the picture flickering oddly then would settle down pretty quickly? Also was it running abnormally hot at any time?

The Z sustain module blew it's transistors. It may have been initiated by the Y sustain board going bad. I always replace both at the same time so as not to waste $250. You will find a Y sus board will run you between $250 to $350 and a Z sus is a little cheaper. I wouldn't replace one without the other. Let me know if this helps.

How do i repair my Plasma TV ?


It's best if you contact a TV specialist to repair it. Once the plasma TV's develop problems, it is no longer a joke. Only thing you can do is send it away for repair. You cannot do it unless you have specific knowledge and special tools besides a soldering iron, pliers and skills. I have an LG Plasma TV. Early last June it had exploded twice. It killed the TV. I sent it away for repair. Then 3 weeks after it got repaired it exploded again. The latest bang was last Sunday (29-6-14), fusing the whole house. I found out why it had happened. I had my Sony Vaio Notepad connected to the TV via an HDMI cable, the same as last time, and the TV made a loud bang. Last time it made a loud bang but didn't fuse out the house, The TV just destroyed itself. This time the TV survived the burnout but fused the house and I was left in the dark to fix the fuses. When I switched the fusebox back on, the TV automatically turned itself on, but I had already removed the notebook. So, I guess Plasma TV's cannot accept HDMI signal from computers. It makes the TV run too hot, as explained by the TV technician but I am not sure. I am still trying to contact LG to question whether this is a possibility that connection of a computer to a TV via a HDMI ports causes the TV to increase its temperature. We are in Winter. perhaps it was my heating system.
You did not say why your TV had malfunctioned. Did you connect a computer or any peripheral that could have upset the TV? If so, prease state what it was connected. It helps understand your case better. So, best bet is to have it repaired by a qualified technician.

I have a Philips plasma 42 with black lines across the screen


I would first check if there is an available firmware upgrade for your model .Upgrade requires you to download firmware from philips website.Then transfer it to a memory stick .Then use a memory stick reader to plug into tv for firmware upgrade.Other wise the set would probably need repair .Possible a bad SSB board or another issue
