Re: Broken Philips 26PF9956/12, worth buying?
looking at the picture it looks like the bottom of a transformer the other part in the pic looks like a transistor on a heat sink imo anywayComment

Looks like an inverter transformer to me.
Don't have a clue what the aluminum heat sync is all about thou
Definitely a mosfet attachedLast edited by freakaftr8; 01-16-2014, 11:13 AM.Did I leave the soldering iron on?Comment

I'm with Tom. If the owner took the time to "identify" the problem, why aren't they interested in fixing it themselves?Comment

Re: Broken Philips 26PF9956/12, worth buying?
I know, I asked him for better pic, waiting for reply.
why?
This should be an FET on aluminium heatsink, right? and maybe burned transformer down?
BTW, this was unsoldered in service, not by owner.Comment

Things don't unsolder themselves while working... if that transformer is bad pretty much guaranteed you won't find a replacement.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Broken Philips 26PF9956/12, worth buying?
Agreed. And the time and effort to get a 26 inch working again unless it's just for personal gain is pointless imho. You won't get much for it.Did I leave the soldering iron on?Comment

Re: Broken Philips 26PF9956/12, worth buying?
What about this, owner says that there is only backlight when TV is connected to power outlet(not turned on!), remote controller doesn't do anything, he was in service and been told that mainboard needs replacemet (some chip on motherboard)

I need a TV for my room, so which idea is better?Comment

Re: Broken Philips 26PF9956/12, worth buying?
You seem to have already convinced yourself, so why are you asking? It looks too expensive and tricky to repair IMO.
I -never- take people's word for it when they say "it just needs a chip/capacitor/diode" etc..Last edited by tom66; 01-16-2014, 12:08 PM.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Broken Philips 26PF9956/12, worth buying?
Technicians are s***bags here in Croatia, they will charge you like 100 bucks for one RAM module replacement, and they will say that motherboard was faulty and they replaced with new one, right, but almost everyone believe that... that's why I'm here asking for help and opinions, hopefully one day I will help others.
Maybe mainboard isn't the problem, technician is.Comment

seems about the same as the UK, it's not unique to anywhere really.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

What if I connect PC PSU to TV? it sounds funny, but it works. I don't mean to sell it so..Comment

Re: Broken Philips 26PF9956/12, worth buying?
You could do that, as long as it doesn't require more than 12V. Some TVs particularly ones above about 19" use 24V inverters.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Only if other components are not damaged due to PSU failure..Comment

Hi all,
I have a CRT (Acorn AKF12, based on the 240V version of the Philips CM8500) which has stopped working. It's making a high pitched noise but not too high. I know this is symptom of a faulty flyback.
What happens when a flyback fails? I see that the main voltages out of the PSU are not reaching rated values, as if there is a short.
There are supposed to be 125V/26.5V/15.5V outputs but I am reading something like 48V, 10V and 8V. If I unplug the PSU from the rest of the PCB, I can measure the expected values.
Can it be a short somewhere... -
When I assembled dreamcast I mistakenly fastened long bolt and It resulted in
cutting tiny trace.
This tiny trace(Total width of white coating is 5.5mm) is between R337,R343 and IC101 and it is covered with white coating in the below screenshot.
Firstly I tried to bridging tiny broken trace with my own eyes...But it is totally impossible..So a week ago, I ordered G1200 Digital Microscope and I magnified this tiny broken trace with it.
But It seems that It is really very tiny trace So I plan to order 0.1mm coper wire from aliexpress in order to bridging... -
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
this tv uses LD7591T ic for pcf boost voltage in psu
the chip is s/c
causing dead no led lit
only 330v across main smoothing caps
so no boosted voltage or stable secondary o/p voltages
ive tried all the usual suppliers no one has this chip
i can order from china but dont want to wait until july
can anyone suggest a supplier here in uk
or maybe possible equivalent
the chassis type is tmp 17.7e la
thanks -
My mother may soon need to upgrade from Win7 (to continue safe browsing, e-mail, and office tasks, without a printer). Right now, she uses an Intel Core2Quad 9550 CPU (not sure of motherboard). Video is either the Radeon 6670 or 6770, completely air-cooled, with fins like a motorcycle engine (I think I pointed a 120mm fan at it). PSU is probably Seasonic, still running after 14 years (I choose quality). I am not sure of the RAM, or the PCI-e wifi chip. Probably 8 GB or 16 GB. Perfect for WIndows 7.
She does not want to switch to Linux. And she does not want to use a laptop because...
