Re: Philips 42pf9946/79 plasma tv
Can you post some pictures of the powersupply ?
If im correct the main problem on this set is the capacitors on the PS. They dont look bulged but the 10uf / 22uf need to be replaced for 100uf if im correct. It was a design fault.
Pictures please so we can help!I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!

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 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... -
Hi
I have here a Philips 47PFS7509/12 LCD TV which came to me with a weird problem : without signal i could access menu, make a factory reset, access menus, etc.
When i applied cable signal to check image, i had normal picture, but TV was restarting.
I downloaded original firmware and applied the update, but the problem remained.
From a colleague i received a "factory package software" which is a lot bigger.
I made another firmware update, but still did not solve the problem.
Somewhere on the way the error got worse, because at the moment the...
