PANASONIC TH-P42S10A - 10 blinks

[tw2005]

PANASONIC TH-P42S10A - 10 blinks. Roughly equivalent to a TC-P42S1.

Just got this a couple of hours ago. 10 blinks on power on. Quick check of the Sc , ok.

Isolated to just the P and A boards, still 10 blinks. Noticed optic jack not illuminating suggesting missing SUB3.3V.

Checked F15V, ok. Checked PA5600 fusible link (smd) , ok

SUB3.3V also goes to SD slot, known to be an issue if foreign objects go in there and bend the pins.

Sure enough , closer inspection , pins bent in all directions, shorting to case taking the SUB3.3V down.

straightened pins, removed short and fired up OK. SD slot still damaged, SD card causes short again but fine empty.

11300 Hrs and panel looks just fine

Nice! I've never used the SD card slot on any TV I've had. I would put a piece of tape over it.

Tom66 & tw2005 is it safe to desolder SD card from the equation to clear the short and run the set with out it..
As the set I have the guy who owns it inserted a SD card then it turned it self off done the 10 blinks and has done that ever since.

So removing the slot will this solve my problem as the pins where pushed right back and no way of clearing it.

well it would, i got a needle in there and straightened mine out but sounds like the if it does not go in push harder manoeuvre was tried.

either that or get the schematics and cut the leg off that has power supplied, it's just that the whole body of that slot is soldered.

but yes you just need to remove the short.

I am assuming you've confirmed that the pins in that socket are bent and shorted.

I removed it and took the casing off the sd card.
It would of been impossible to clear this short as they where curled back touching the metal casing.

sounds interesting. You just leaving this missing or going to try and find a replacement to solder in?

the guy is not too fussed about so Ill just leave it out.
save him some money and possible future hassle.

Didn't work. disconnected all the other boards from power still no different blinks to say other boards are faulty.
I am assuming mainboard has failed as psu board is new as another guy before me replaced it for unknown reasons.

But the SD slot was shorted, yes? And you've confirmed that the 3.3v rail is no longer shorted to ground?

Never been good on the A-boards but all I can suggest is you see what voltages are monitored for 10 blink and see if you can find the one missing on start-up.

I had a 50 with 1 blink and turned that into a 10 blink, must have shorted something, gave up and used a G10 board and bypassed the Fan SOS since it has none to get that working.

very rare to see boards on Ebay here though.

Would there be a sense connection something that would sense that the sd card is in there that will need bridging together.

Re: PANASONIC TH-P42S10A - 10 blinks

yes the sd card was defiantly shorted. you could do the continuity test on two pins and they would have continuity.

I doubt that's the issue

That's unlucky, would have put money on it clearing the fault but if you're foloowing someone elses failed attempt, who knows what's been done.

Yeah lets see what readings I get tomorrow.

I will let you know tomorrow night.
