Philips 32pfh4309/88 restart problem
Hi to everybody, i have a problem with the tv in title.
The tv reboot it self when i give power to It.
Sometimes show the Philips logo and restart, sometimes only the backlight on and off.
There isn't Power led on.
I opened the tv and i don't see any blow caps or burn PCB.
I read in other discussion about an upgrade firmware with USB, i just try It without success.the TV restart before start the upgrade.
I think that in my case Is an hardware problem, what i can check and what are the problems for you?
Thanks to everybody -

Re: tv lcd Philips 42pfl9632d/10 Power board ko
With all connected at the two pin it the relay arrive 5v dc,this meaning that the some V is sending by the ssb. The old problem Was that the ssb didn't sent the 5v to the psu (One diode burn), this time is different
For forcing the psu what pin i must jumper?...Leave a comment:
