Philips PLCD190P5 power supply

Re: Philips PLCD190P5 power supply

probably R064 is open when you measure it out of circuit.

So I removed it from circuit and that's when it measures .983k ohm, in circuit it was .851k.

So as the others suggest would it hurt if I use a 1k ?

In the plcd190p1 (schematic) they use the same pfc ic. I suspect the resistor (3064) is the one connected to the CS pin of the ic, and to the source resistors of the fet. this resistor is 0E (0 ohms) for the plcd190p1.
In the plcd300p3 they use a 330 ohm. so I can't be sure. here is the shopjimmy picture but it is hard to tell the value

Thank you for the response R_J, removed from circuit the resistor reads .983k ohm. It is definately burnt to a crisp, removed and close up if it had a color code band it would be black with no tolerance band.

What are you seeing that makes you see this board and that schematic similar?

A resistor reading 0.983k Ohms=983 Ohms. Unless it was suppose to be 1.0 Ohm, I would say that is OK. I would probably temporarily try a 1k Ohm in its place.

Remove one end of R064 and measure it, It does'nt look burnt in the picture, this plcd150p1 looks similar
The plcd300p3 schematic uses a 330 ohm

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.
