Re: Philips 32PFL5404H/12 Doesn't Turn On
Dear All,
I have a similar TV with a different problem:
[url]https://www.badcaps.net/forum/showthread.php?p=561465#post561465[/url]
and everything seem to point a mainboard disfunction.
In my experience, mosfets are quite prone to failure and i found on ebay a repair kit for this kind of tv with 4 mosfets and a chip.
before I should rush on this I noticed 7101 and 7102 looked like the one in the kit and Tampsa said to look at thoose in this thread.
My question...

Re: Philips 32PFL5404 wont turn on -> status led blinks twice
Ok so something really is preventing start...
Where should i start my investigations?what about this Led code? does it tells us something.
Something else : i must assume psu is ok since it was bought as new and working on the bay but it gave similar results than with the old "fried" one: makes me think something is wrong on another board, putatively the one That handles video, why not the ccfl tubes?
I had some results testing mosfets in the past since they are also prone to fail...

Re: Philips 32PFL5404 wont turn on -> status led blinks twice
Dear budm
I measured voltage on the "off" i.e. standby mode and while holding on button wich yielded similar results. Actually the proble is the tv set won't turn ON and halts somewere in selftests, infinitly (hopefully not) stuck in standby
It is WEIRED that NC (not connected?) pins actually oscilate from -0.1 to 0.1Vdc while ground pins give a steady 0 so its not my DMM that acts weired so i imagine that it's some parasitic current
Here the readins I got (same while...

Re: Philips 32PFL5404 wont turn on -> status led blinks twice
Dear all,
late reply caused by tons of work.
Since the tv doesnt actually have a switch it is pemantly in standby. I could measure voltages without the ac line connected but it doesn't make sense right?
so TV "on"
CN5:
DIM 0.26Vdc
CN4:
3V3Stdby 3.24Vdc
Standby 3.24Vdc
+Vsnd 0.55Vdc
all other rails are <0.1v ( guess its noise/caibration issues)

Philips 32PFL5404 wont turn on -> status led blinks twice
Dear all,
I'm trying to fix a Philips 32PFL5404 tv that wont turn on.
It only does a status led double blink each 3 seconds over and over.
I changed the psu which shoed obvious signs of overheating by a new one from the bay (model PLHL-T708A) but nothing changed at all.
I am willing to think the new psu is ok so the problem sould logically come from the ortherboard that handle graphics, inputs-outputs, etc...
Thanks by advance for your tips
