Panasonic plasma TC-P42C2 10 blinks

[stepka]

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

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 multimeter

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

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 legs

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.

does the meter have continuity mode or diode mode with a beeper? That is if you touch the 2 probes together it just beeps?

A short is low resistance if you touch the probes together the meter will read zero or very low ohms.

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.

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.

continuity check page 12 of the manual.

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.

that's a continuous beep?

Re: Panasonic plasma TC-P42C2 10 blinks

And it's marking is RJP63F3A or F4A ?

3a and its a constant beep

3a and its a constant beep

and the results for thr RJP30E4 on the Ss at Q001,002, 021,022 were?

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.

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.

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 other

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 = 1.4

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 ok

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.
