Re: SSC9522S - Current-Resonant Off-Line Switching Control IC
Hi, I am trying to repair this tv for myself, it is my hobby. As I mentioned earlier, exact replacement is NOT PRODUCED anymore, so you can´t buy them. For me, there are two options:
1. believe that these 0,1 ohm 1w are good and I am just not experienced to measure them properly (I mean my multimeter is not so precise) OR
2. replace them with stand 0,1 ohm resistors (flame resistant)
which one is better and can cause less damage?
Also could you please review documentation...

Re: SSC9522S - Current-Resonant Off-Line Switching Control IC
So is better to go with standard 0,1ohm resistor?Leave a comment:

Re: SSC9522S - Current-Resonant Off-Line Switching Control IC
That was clear from the very beginning, but as I said, they dont have those in 4 diff. shops and cannot order them, as the lowest value possible to order is 0,1ohm 2w. That is why I was asking If I should replace them with those or regular resistors. ?...Leave a comment:

Re: SSC9522S - Current-Resonant Off-Line Switching Control IC
Yes, I checked both mosfets on the board. They are ok. They dont have the same type of resistors anywhere, so thats why I was asking what is better replacement for 0,1ohm 1W, if its 0,1ohm 2w, or normal 0,1ohm resistor?? Can you please answer my second question too? (transistors identification)Leave a comment:

Re: SSC9522S - Current-Resonant Off-Line Switching Control IC
Hi, I ordered IC, changed 1ohm resistor, problem is with 0,1ohm 1W - they dont have those.
1. Can I change them with 0,1ohm 2w, or better to replace them with normal 0,1ohm resistors?
2. Did I identify W2A 35 transistors correctly? - I need to know correct name/type of them - please review attached spec sheet and let me know.Last edited by Kalias; 01-24-2018, 12:54 PM.Leave a comment:

Re: SSC9522S - Current-Resonant Off-Line Switching Control IC
OK, I will order new IC and change those resistors.
1) Could you also advise on those transistors, If I have identified them correctly and should not have (bad one) "diode continuity" between base and emitter
2) is ok to test those two mosfets Q9101/Q9102 on the board?Leave a comment:

Re: SSC9522S - Current-Resonant Off-Line Switching Control IC
Too late, I took the IC off board (hopefully I ll be able to put it back). Continuity is still between PIN8 to PIN4 and PIN9, not to PIN 10 anymore. Resistance is pin8-pin4 = 2,1ohm , pin8-pin9 = 2,9 ohm, pin8-pin10 - OL . If I verified PS-ON, I clicked on-off button few times to check if any voltages appears, but its dead 0, and it should be 2,7-3,3 approx in standby, I only have stable 5v. Ok, by those resistances, is IC ok? The other thing, Q9101, Q9102 were tested in the circuit, must they be taken off?? Plus I found...Leave a comment:

Ok, diodes and zener diodes are ok, tested them off the board. I will have to take the IC out and then I let you know the resistance. I measured those two mosfets on the board, do they have to be taken also off board? There are quite a lot of smd resistors around those mosfets, so I leave them for now and focus on the first items. All I know that this will not be an easy fix. Thanks for now, let you know more after testing.Leave a comment:

Re: SSC9522S - Current-Resonant Off-Line Switching Control IC
Ok, let me start from the very beginning. I have TV Philips 40pfl3208h/12. It was gifted to me as a faulty with no sound or picture. I disassembled it, found one bad led. As I didnt have proper replacement led chip and it was nowhere to found, I decided to cross/bridge this led with the resistor of the resistance measured on other leds as at that time, this was the most fastest and cheapest option. After that, TV worked absolutely ok, as new, but just for few hours - on-offs. I then disassembled it again, to check backlight...Last edited by Kalias; 01-23-2018, 11:23 AM.Leave a comment:

Re: SSC9522S - Current-Resonant Off-Line Switching Control IC
I checked it within/in the circuit. This IC gained my attention when I found a smd cap close to pin 8 which seems to be shorted/bad at first (showed continuity). After I removed it from the board, cap was ok, then I start searching around and my logic tells me that you cant have continuity through this chip on both sides of this smd cap. But I need to know for sure, If it could be ok, or not. (cause I am not good in changing these smd chips and I don't want to cause unneeded damage to the board)Leave a comment:

SSC9522S - Current-Resonant Off-Line Switching Control IC
Hi all, I have this IC located on lcd TV power supply board. I would like to know If there should be continuity between PIN8 (REG) with PIN 4 (GND)/PIN 9 (RV and PIN 10 (COM) or not??? Thanks ahead for your help.... -
Re: Faulty Philips PSU (715g5246-p01-000-002s )
Hi, have you succeeded in repairing of the board? I have the same issue, spent lot of time trying to diagnose the fault, but with no success.Leave a comment:
