Hello all, been a long time and am hoping for advice on an lcd philips 32" tv repair. The model number is a 32PFL5332D/37. As far as I have found (from the net and this forum is no luck with a schematic for the actual PS board.)
I got the tv not working and immediately dove into the back to check the powersupply. So far I have found (4x) burnt 6.8G ohm resistors that are in parallel of each other, and near another resistor that is completely burnt so much that It is impossible to make out the color bands. I have found (1x) P20NM50FP N-channel mosfet near the burnt resistors that reads Shorted (31 ohm gate -drain and 2ohm Drain-source) and found a PFC controller L6562 that shows low resistance between 1, 2, and 3 pins (I will most likely like to replace since it is a cheap assurance) I will attach a few pictures of the board, and I have found a few pictures from other members that show the burnt resistor in question, however I simply cannot make out the colors myself.
The resistor I do not know is R064 and it is below the negative band of the biggest electrolytic capacitor on the board. It reads .851k if I measure it with my meter while in circuit. My question to the pro's is, what would you do in this scenario and is there any other things I should test/ consider. I am willing to spend a few bucks and order the parts from digikey I have already found suitable parts for the ones I can identify and can order them to try, but the one burnt resistor is throwing me for a spin.
Also I attached the best photo I could find online that shows the resistor but I cannot make out the colors.
If anyone can offer any assistance I would much appreciate it.
