Hello everyone, I've read everything that this site and Google has to offer but I haven't found an answer. I have a TV that I acquired (model in subject) and it blinks a code 10. I unplugged the SN2 and SS11 connectors and it still blinked 10, then I plugged in SN2 and I blinked 7... Please help

Re: Panasonic plasma TC-P42C2 10 blinks
Disconnect sn2 ss11 p35 , 3 white ribbons at the a board and turn on. Check if it errors then Turn it off and let it sit for a good 5-10 minutes. Don't reconnect until it has sat because voltage will be present and arcing can damage boards or the panel.
Report what happens. Do you have a multimeterComment

Thanks for the reply. No error. Yes I do have a multimeterComment

Re: Panasonic plasma TC-P42C2 10 blinks
Set the meter to ohms and measure the resistance across pins at sn2. It's going to be ss sn or both that have failed. If you know how to check for shorts shorts check q661 on the sn for shorted legs on the ss check any of the rjp30e4 transistors for shorted legsLast edited by tw2005; 07-31-2016, 12:04 AM.Comment

Re: Panasonic plasma TC-P42C2 10 blinks
There is resistance on when I checked the 2 pins on the SN2 connector. I dont know how to check for a shorted leg.Comment

Re: Panasonic plasma TC-P42C2 10 blinks
It's a Craftsman 82372 meter and I'm not sure if it has any of those modes, but I can set it up to beep if I touch the 2 probes together.Comment

Re: Panasonic plasma TC-P42C2 10 blinks
that would be handy then you can just probe any 2 legs on either of those transistors I mentioned and it it continually beeps, it's shorted. Start with the SS , there are 4 x rjp30e2 and if one has failed you'll find all 4 are shorted.Comment

continuity check page 12 of the manual.Comment

Re: Panasonic plasma TC-P42C2 10 blinks
Q661 will beep when I connect any two of the three posts, no matter what sequence I do.Comment

Re: Panasonic plasma TC-P42C2 10 blinks
And it's marking is RJP63F3A or F4A ?Comment

Re: Panasonic plasma TC-P42C2 10 blinks
RJP30E4 at Q001, Q002, Q021, and Q022 all beep (only the outer 2 tabs are connected to the board) when i touch any if the 3 tabs.Comment

Re: Panasonic plasma TC-P42C2 10 blinks
all 3 three are connected just that the backing is soldered to the board which is that stumpy centre tab.
Is this a continuous beep? What is displayed on the meter when it beeps?Disconnect SS11 and try again.
If it's a continuous beep sounds like that board is also shorted which is possible that either one can fail the other as they are connected to each otherLast edited by tw2005; 07-31-2016, 12:31 AM.Comment

Re: Panasonic plasma TC-P42C2 10 blinks
The board has been removed from the TV for testing. Here are my readings (e post = right , g post = left and c = center)
Q021 Right-left = 14.2ohms, center-left = 14.3, center-right = 1.2
Q022 R-L = 11.9, C-L=11.7, C-R = .9
Q001 R-L= 22.6, C-L = 22.6, C-R = 1.4
Q002 R-L = 21.6, C-L = 22.1, C-R = 1.4Comment

Re: Panasonic plasma TC-P42C2 10 blinks
yeah well if that's in ohms they're shorted.
Replace the SN and SS boards
Shopjimmy has a shed load of REV AC which will work. they're most likely new pulled from smashed TVs rather than pre-used
https://www.shopjimmy.com/panasonic-...c-sn-board.htm
For the SS you'll have to find a good used one or send it in to PTS Electronics for a rebuild but used is cheaper
TNPA5072AC, TNPA5072AF should work okComment

Re: Panasonic plasma TC-P42C2 10 blinks
Thanks for your help! Is there any way to replace whats necessary on each board? I can solder.Last edited by stepka; 07-31-2016, 12:59 AM.Comment

Hi,
anyone able to provide the service manual for old plasma Panasonic TX-P42ST50E?
It turns off almost immediately (0~5 seconds after pressing the on/off button) and starts flashing the red diode 6 times.
I disconnected the left-hand side board (SC?, both the ribbon cable and the power cable to it) and also another ribbon going to bottom left board. Then the led signal is 8 flashes. According to service guide to another Panasonic plasma it would mean the left-hand side board is faulty. But I'm not sure it 100% applies to my model.
I checked that board for any obvious faults... -
Hello,
Stopped by this site trying to fix my parents Panasonic Plasma TV.
Model number is TH-50PZ85U
Power comes on and the red power light stays on solid.
Did a few checks like hold the power button on for 60 seconds, hold the - Volume while holding the menu button, no luck, still@ blank grey screen as the screen lights up very vague.
I also hear a few clicks.
I also think my parents said there was a thunderstorm and the TV failed after that.
Section 6 in the service manual talks about power and no screen,...10-30-2024, 10:09 AM -
Hello,
My Oct 2012 panny plasma quit working yesterday.
It was on when it happened. It let out a bit of burned plastic/circuit board smell. I was not able to find any burned parts though.
Now it produces 8 blinks. According to the repair manual, that points to SS/SS2 board(s).
I completed the steps in the guide: unplugged SS33, the TV turned on with a black screen, no blinking codes. Then I checked the continuity between pins 1 and 2 of the connectors SS52, SS54-SS57. The continuity is ok in all of them. Guide suggests to replace SS/SS2 boards so I placed an order... -
Hi everyone!
I happened several times, in the search for help from the web, to consult this very interesting forum.
So I decided to sign up and I intend to participate actively by making available my knowledge and experience on the subject, I'm a new user but at the same time I'm old in the sense that I have 4 decades of experience in repairing and designing electronics but above all I'm a great passionate about the subject.
Having said that I come to the gist of my post on the forum as the title suggests.
For my passion for technology I'm now collecting several... -
Bought this TV used not working, panel flashed briefly on power up and it was blinking 8 times, a quick look on SS board revealed a common fault on the 3uF 250V capacitors, C201 to C205 (C1620X in the service manual), the solder joints were all cracked, C201 and C205 pins were darkened and some sparking had occurred on them, C201 was split open and clearly overheated in its last hours, replaced that one and resoldered the others, 8 blinks fixed.
Also the previous owner broke the antenna connector by taking the TV out of the wall mount forgetting to unplug it, I desoldered the tuner...
