Re: Panasonic TC-50PS14 10 blinks

Are you sure yours is a 6065? Mine is a 6055.

Nevermind. You're right. 6065

Re: Panasonic TC-50PS14 10 blinks

Anyone dealt with this place before? I've found everything except D421 and D422 here. Too bad they don't have those as well. That's the 2x MA3DF40

Re: Panasonic TC-50PS14 10 blinks

I was just looking at that site as well. I found the original replacement for Q601 and Q660 on digikey (out of stock) and one that I think is close enough- minor differences in gate charge and input capacitance. No suitable replacement for the 6065 I could find, Might just have to order from that other site, just trying to decide if I want a quick fix or a complete rebuild. Went through checkout and they want 20$ for shipping.....Hate it when they rip you for shipping

Also found D652 (8894) shorted as well

Re: Panasonic TC-50PS14 10 blinks

Yeah, that's going to put it up to half of just buying the kit. I can't decide either. Hate waiting for a cheaper board to pop up. Could be a while.

I'm a little worried about using an alternate part for that one. Looks like its a proprietary chip that Panasonic uses on their plasmas. I just checked two newer Panasonic sustains I have here but no dice on that particular IC.

I can't seem to locate this one to check.

Found it. Seems to be ok on mine.

Re: Panasonic TC-50PS14 10 blinks

Yes I used the jumper to test the buffers, did you have the link to that other thread? I was looking over the schematic last night and was noticing this diode was tied into the drain of two fets so I was kinda expecting at least one of them to be blown. Im going to try and fix this at the component level as I cant really justify sinking 200$ into this tv, if I can get it to pass the self test I will buy some buffers for it. At least I have a schematic for this one I will test out all the components around that vsus circuit.

No luck, may have been a closely related model with similar design. I tried the board number nothing looked familar.

I may have some data for the parts identification and suggestions. Probably find some are obsolete and replaced with updated equivalents but this is one of the battles trying to find them without blowing the budget.

I would not rely on purely a kit to solve all issues.

Here's that toasty board similar to yours.

Thanks for the recommendation. I've asked for a quote. So far at least on my board it seems as though just these parts are bad. I may take the plunge and try them. Will keep everyone updated. I believe the board Caleb is working with took a much worse hit.

Re: Panasonic TC-50PS14 10 blinks

maybe some info similar design, 42". https://www.badcaps.net/forum/showthread.php?t=27921

There's quite a few tiny parts that can fail too, inverter ICs, FET drivers, voltage regulators, SMD transistors.

Found a doc which I can't find for SOS 5 for these

Q16701, Q16702, IC16773, IC16771, IC16464, IC16465 42G10 model, I would check these too

Re: Panasonic TC-50PS14 10 blinks

Will do. Still can't believe the price this board is commanding online. One just popped up on Ebay since last night in the US. $200

Re: Panasonic TC-50PS14 10 blinks

Saw that one. It's an auction though so who knows what it will go for. Regardless, I don't want to be in over $100 for one if I buy the whole board. What's hard to believe is the very similar sets with SC boards at a fraction of the cost.

Re: Panasonic TC-50PS14 10 blinks

Or this one. It looks so much alike I'm tempted to buy it just to see if it has the parts I need. Maybe I could find the schematic for it and compare parts.

Re: Panasonic TC-50PS14 10 blinks

I got no hits for the transistors, just the SMD diode

[aaronwt6]

Re: Panasonic TC-50PS14 10 blinks

Yep. No luck on my end either. Looks like this is the closest match appearance wise but I haven't found a parts list yet. See this one for as cheap as $25.

Re: Panasonic TC-50PS14 10 blinks

Good luck with this list.

[aaronwt6]

Re: Panasonic TC-50PS14 10 blinks

Ok. Yeah. That's a bit overwhelming. lol

Really appreciate the assistance. With the time I've spent so far I might as well have just sold the other boards in the set and called it a wash. Guess that's 1/2 the fun thought right?

Yeah that looks closer to yours at a glimpse. REV AC is 42" though not 50 going by SJ.

Re: Panasonic TC-50PS14 10 blinks

This set uses the same boards as the PZ series?
