Hi Mulja,

Neither first nor second one worked for me, perhaps a secret handshake, well  - have a beer - homebrew - Chris.

Hi guys

Sorry i am a newby here just my first post, dont know if its in correct thread..

I have a Phillips 42PF5521D/10 model also..

somehow my HDMI ports stopped working, and also my TV sometimes.. when i press the power button,  i hear 2 clicks and the green light starts flashing but no screen picture .

So for the No screen picture issue i managed to resolve it.. everynight when i stop watching tv, i just disconnect the POWER CABLE from the mains.. and next day when i want to watch it again just plug back power cable again and it power up fine.

But recently the HDMI ports stopped working.. just says NO HDMI INPUT SIGNAL.. this happens with all devices..

PS3, HD DVD, HD SET TOP BOX from my TV PROVIDER ...

Anyway of fixing the HDMI ports on the board? what sort of components busted could lead to this problem ?

thxs in advance for your replies guys..

cheers

Hi TT 10,

Dug this up from back threads -

Philips 42PF5521D  LC4.41E   (Have S manual)
Power – two different boards possible Fujitsu and - who knows ?
1. Won’t start, relays click and led flashes twice – usual prob is caps  C2508 C2540 C2465 (all 100/16) C2113 (220/35) Check also ‘tiristors’ 7050 (sup85n15)and 7052 (sup 25n15)

All the best - Chris.

and - I know
FHP (FujitsuHitachi) PSU 310432842741
I have documentation for this PSU,
but the panel could also be a Samsung or
even a LGE (Lucky Goldstar) panel and they are using
differents psu so pls more info, perhaps a
label with numbers on.

Hi Folks,

Guess some piccies would help - never seen the set myself, so over to you chaps -

PS - Always send a piccy - we won't laugh - almost promise - (Hero but not at all blue'ish - Yellow submarine, perhaps)  Chris.

Hello guys

sorry for late reply had some problems in finding forum again lol.. did not save page on the favourits baaaaa...

ok i will try to open up the back panel to see the components model..

so u think the Power Problem could be leading to the HDMI ports issue also? or changin does 100uf /16v will just resolve the problem for the greed led blinks?

i will try to update with some pics here, but this model was bough in the United Kingdom in 2006/7 year of production

Hi,

I also have this model with the same problem of the blinking green lights, clicking relays, but no power up.

I have removed the power card and it is identical to the one in the picture linked to above (3104 328 42742) and confirmed by a label. However, I don't appear to have capacitors numbered 2508, 2540, 2541 & 2465.

As a total newbie to this, I can see what appear to be capacitors with the following numbers : 2292, 2294, 2022, 2225, 2269, 2261, 2229, 2230, 2510, 2505, 2052, 2664 & 2662, as well as 2113 mentioned in the previous post along with the 4 above.

Can anyone shed any light on this as I am almost at the point of junking the TV.

Hi Plasma folks,

Just had my first one. Cust said that originally it came on normally with a 'Sony' degauss noise, this one just clicks with a one/two green led flash and now't else.

Power panel is 3104.328.42742 that some folks say is Fujitsu though 'Philips' is printed in the middle.

Took a piccy - any more thoughts  ?   - Chris.

PS - Just tried Mulja's link again - worked for me this time - thanks 'M' - anyone know where I can get some SUP85N15 and SUP25N15 at a decent price  ?

Hi Jones180,

Slipped in my Babel-fish, but it still seems crap - Chris

Hi Chris

I used to be an imature Led and I used to have a nightlong blink as well, but I have taken a couple of magic beans and I feel fine now.

Im not sure whereabouts on the timber the psu is though?

I would love to bonk a schematic for the LC4.41, perhaps you could arrange it for me?

Hi Brian,

Guess you're one of those super-bright blue leds these-days.

Glad to try cater for your timber-bonk request if you could discover cheap source of (sup85n15)and 7052 (sup 25n15) 'Magic Bean' Fets  - Chris.
