How did you test the caps - with a capacitance meter or ESR meter?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
For service manual, schematic, boardview (board view), datasheet, cad - use our search. -

I there i used a capacitance meter to test them but i removed every cap out of the board to test them?Comment

Really need an ESR meter to check them. The capacitance can be ok but the cap still be bad. What are the voltages coming out of the power supply?Comment

i dont now as i removed the board to test every think i will have to put back in and do a test on themComment

A nice clear picture of the PSU could help.....TELEFIX

Hello, guys!
The same 32" Philips TV I was having video issues, but now I don't have standby led at all. Someone here shared with me the schematic of the power supply, and checking the voltages, I see right after the resistor R604 I'm getting 1.6 v which is too low for enabling the Gate of the Q601 mosfet (the diagram says 4.2). On the R614 resistor I'm getting 181 V in and 117 V out, then through R603 I'm getting the same 117 V in and 59.9 V out, finally getting the latter voltage in the R604 BUT getting just 1.6 V out, which is the voltage that goes on to the Gate of the Q601... -
Philips 8200 series 65PUS8204/12 stuck at Philips Logo, it does not reboot it just stays on the logo.
It does power up when pressing the power button.
I already try the power button while plugin the plug with no result.
Also put the latest firmware autorun-TPM191E_R.001.004.100.000.upg on a MBR/FAT32 USB stick at USB port2 with no result either.
Could this be an PSU or eMMC issue ? -
Hi folks,
I'm suspecting the actual CCFL or EFL being bad, just not sure how to test, but would like to confirm.
TV clicks upon plugging in AC. When I press the PWR ON button, clicks again.
LED on the Main board comes on green (Assuming some diagnostics), Blue LED on the TCON comes on also when I turn the TV on, but turns off about 30 seconds later.
3V3 ST is on (3.26 V)
Standy 3.3 V (off) when I press power button goes to 0.16 V
12Vssb is 11.75 V (on), 0.18 V (0ff)
+12Voud is 13.8V (on) ~ 0V off
-12Voud is -12.4 V (On) ~0V... -
Hi:
i am trying to repair this Christmas lights from my parents. They are incandescent lights, no led lights.
I have tried with 12V a 24V small lights that I found in Aliexpress but is obvious that are not the right ones. They last microseconds connected. Do they blow because of Amps or Volts?
If I measure the Amps in the string........it's only 90mA. If I measure the Volts in the "green box"......it's between 0 and 190V, but doing a little bit of maths from the number of bulbs in series.......it's only about 6V per lamp.

Hi all,
Wife has 2 Philips hair curling irons half defective - after learning how they're supposed to work and testing them, it turned out that both have defective power cables, and both on the same place; broken wires due to wire bending.
As they were both relatively easy to disassemble, and cables are plugged not soldered (as they can rotate in the handle), I was sure it would be easy to find replacements. But - NO! I'm unable to find anything similar on ebay or Aliexpress.
Not sure if this is something Philips proprietary, or a standard, but the cable plug...
