Question about Philips 42PF9631D 42 in. Plasma Television
The green LED turns on but no A/V. The A/V would only turn back on if I unplugged/ plugged the set. But It would take +1 minute before the picture would be visible and the picture would turn on then off then on then off before it stabilized. Philips asked me to do a firmware upgrade, but I was already at the latest version. I tried to re-install the firmware but nothing seemed to happen maybe since I have the same version as on the USB. The TV continued to work for several weeks as long as I unplugged and plugged the power. Today I am unable to get any A/V at all.
Listen if you see bulging capcitor replace them you be glad you did and you will have a working TV!! Trust me i did this on a Emac even though there not the same type of unit it really doesn ot matter the problem is this a bulging cap means its not holding its correct charge and thus not able to power the rest of the TV!
Change the caps you be a happy camper you did and you will S$VE big cash!!! If you did Trust me
Thanks for using fixya I hope this helps you! If it does hit accept you be glad you did!

Firmware upgrade is not the solution. There's a hardware problem inside the TV. You need to replace the INVERTER BOARD. Check the link below so that you could have an idea how the inverter board looks like:
Hope this helps and have a great day!

You can do a reset if you leave the device unplugged longer. I had mine unplugged overnight and it solved all issues within the 3 years of use. If it does not solve it you may check for loose connections internally. If there are internal components that may fail the TV should give out errors by flashing of lights. See if there are any.
