Hi, i have a philips 37PF9975/12 and this displays the same symptoms as a lot of these sets, it starts up ok then after about 15 mins it goes to standby for 10mins then comes on again with the led flashing red codes 1 long and 4 short but working fine, then 10-15 mins later to standby again, i have downloaded the service manuals from www.electromaniacs.com ( they have schematics for everything) and from what i can gather (me not being an electronics wiz) it enterprets the codes as a problem on the PSU with the 5v supply, if anybody could shed any more light on this problem for me i would be very grateful
P.S Chassis number is FTP2.2E AA
Thanks
Error codes are basically a referance point to begin the troubleshooting. Th micro monitoring the 5 volt line in this case has no idea whether there is a problem with the 5 volt power supply or one of the circuits pulling the line down when it fails.
Plasma TV sets are board replacement since the so called schematics lack about half the circuitry in the set (nor do they have any voltage or waveform measurements).
Unfortunately, the 5 volt line is probably fed to just about every board in the set.
BTW, I realize there is a thread on this model with some kit you can buy on Ebay but you must realize that most plasma sets have numerous voltages being monitored that will trip a micro to cause the set to shutdown and throw an error code. It's not necessarily all caused by the same problem.
ok thanks for the input, looks like it will have to be the tv repair man then!
