Re: Panasonic TC-60PS34 (S30 plasma) 8 blinks
Yeah, I noticed that. The current unit has the AE suffix board. But I did notice that the boards ShopJimmy has are actually different codes: TNPH0914 1A vs 2A. (The AE is the 1A, the AU the 2A) I was thinking, maybe the previous owner tried to swap them, put in the wrong one of those because it came up on SJ, and then couldn't figure out the problem from there? Is that a possibility, or should those two boards be basically interchangeable?

Re: Panasonic TC-60PS34 (S30 plasma) 8 blinks
Well, despite the lack of expected behavior when isolating the SS board, I was convinced by another tech to go ahead and try swapping it anyway. (He has tons of experience under his belt, and heck, it's not like I'm sure anyway.) No luck, though, and the SC board has also been swapped to no effect. So this may also end up being another "no luck with 8 blinks" post.
My remaining possibility is the A board; however, after some Googling and finding that the supposed replacement boards for this model don't exactly...Leave a comment:

Well, that's interesting. I hadn't heard that one before. No, the panel isn't even illuminating. I suppose I can test the Sx boards more thoroughly.Leave a comment:

Re: Panasonic TC-60PS34 (S30 plasma) 8 blinks
Well, I'm back from the trip.
Sure enough, A31 removed gives six blinks. TV still stays on with only A20 and A32 removed, which honestly seems puzzling.
I think I'm going to order an A board in the next day or two and keep my fingers crossed unless anyone has an epiphany otherwise... not that I particularly *want* to order the most expensive board on the thing, but I don't really see another alternative.Leave a comment:

Re: Panasonic TC-60PS34 (S30 plasma) 8 blinks
That makes sense. I tried all three off and wasn't able to get it to turn on... because I was using the side panel, of course. I'll test it again when I get home at the end of the week. I'm guessing it turns on fine - which, if it also turns on fine with only A20 and A32 off as it did before, puts suspicion back on the SC board again I think.Leave a comment:

That's interesting. I may try to isolate the buffer boards, just to see what happens.
To clarify the testing results: when I disconnected A20 and A32, it was those alone - I reconnected A31 for that. The chart indicated that it should stay on if all three were disconnected, but not just A20 and A32 - it should have still given me a blink code. Just thought I'd clarify as that detail may lead to a different conclusion.
Will try A31 again when I get back, and power on from remote instead of the side buttons -...Leave a comment:

Re: Panasonic TC-60PS34 (S30 plasma) 8 blinks
I would too, but it's not looking good.
Removing connectors, for comparison to expected removal performance (slide 86):
SS33 removed: still 8 blinks
SC20 removed: 8 blinks
after this, I was starting to suspect the SC board (and the SS board was pretty much off the hook after the first one, I think, it seems super easy to isolate), but then:
A31 removed: TV stays off (!)
A32 removed: 6 blinks
A20, A32 removed: TV stays on, black screen
Am I right in thinking...Last edited by slinkygn; 12-29-2013, 12:08 PM.Leave a comment:

Re: Panasonic TC-60PS34 (S30 plasma) 8 blinks
Yeah, I need to fix this thing already so I can sell it and likely get something a little smaller.
That document was just what the doctor ordered -- thank you! Followed the TS flowchart on slide 75. Isolating the SS board lead to 6 blinks instead of 8; I don't have my good probes on me so I can't test the connections like it says to, but it seems like I'm going to be replacing my A board, not my SS board. :/ (Much interested in component-level fixes now -- those things are a bit more expensive!)Leave a comment:

Panasonic TC-60PS34 (S30 plasma) 8 blinks
Not a *ton* here on Panasonic plasmas with the 8-blink error, it seems... most folks seem to get 7 or 10. (8 blinks = SS SOS, from what I gather.)
Somebody on another thread mentioned FET issues on the SS board. Can those be tested in-circuit? I'm getting low/no resistance across a few of them, but don't have a circuit diagram so can't say if that's because of a short of the FET itself or because of something elsewhere in the circuit. (For that matter, I got similar readings on some of the SC board FETs, which I tested just because I was suspicious of that board as well.)

Re: which SSD should i get?
Sandforce problems are basically a 2011 thing. You're not going to find any problems with any modern Sandforce controllers, save for a few minor issues that already have firmware updates fixing them (a situation which every SSD manufacturer finds themselves in, including Intel).
840's a great drive, but I'm surprised nobody's mentioned the 830 yet... the 840's "predecessor" hardly performs like a predecessor. That sucker screams.Leave a comment:
