Should cost just around $62 AUD delivered.

Checked SD module. And getting a beep between GND and the ribbon connector middle top that connects between the SD and SU board.

Re: Panasonic TH-P46G10A

Ok. Tested the SU between GND and the four ribbon connectors. Getting a beep on the second ribbon connector on about four pins.

Tested the SD on all four ribbon connectors. No beep.

Could very well be ok if no dead short. If you know someone with another meter like a fluke you could keep testing but with the link I gave you for a pair of boards, i would buy both at that price.

before installing any used board, test the same just in case they too are DOA.

that's not an area to test if you're talking the tiny ribbon that interconnects at SD11

Perfect. LOL 4c diference, weird. So these are the correct boards for my tv then!

At that price its hard to justify even continuing testing. The SC board is fine (hopefully) accoring to the bypass test.

Is there a reason for the su/sd boards dying?

Re: Panasonic TH-P46G10A

Why the difference in price - Same product right, just a diferent tv model?

I can't give you any specific reason. They work pretty hard, most electronic devices have a life.

5 year old TV, for first failure not too bad. I've got a 2010 V20 and the SC board shorted on that at 14months and about 2000hrs use. Another I fixed had about 3000hrs, SC,Sd,Su all shorted.

Both have been running fine 18 months later with the boards replaced.

plenty of 2011/12 models have been having shorted Sc boards both in wty and just out reading some of the stories.

The model before yours the PZ80/PZ800 series seem pretty robust but have a PSU weakness which usually is an easy and cheap fix with a tiny 1uF ceramic cap that goes bad.

Most of the G10/15 failures I read are Sc board or buffers.

A bad panel can kill the buffers. I don't know of anyway of testing to see if the panel is the issue, so fingers crossed just the buffer quit and should be good with replacements.

just be sure to test them first and refitting the panel ribbons can sometimes be tricky.

If you get horizontal lines, that means a badly seated ribbon. Don't attempt to adjust them with the TV on, always shut it down, reseat and test again.

probably around 3 weeks from the US

please yourself. direct from his website you save a few dollars as the ebay price is inflated slightly to cover their charges.

His website is fairly new, I think he's trying to get away from Ebay as much as possible.

Same part used in the 46S1, and the g10/15. The U1 however is a lower spec and has no heatsinks, boards have rev or suffix AC for those.

Don't try to figure out why , he has 5 pair so good chance they're "new" from new TV damaged in transit but he'll only advertise them as used regardless.

Quite often I come across variations in price with him and probably because of a different model but same part.

I recently got a Sn board for $30 and a SS for $13. The same parts on his site normally sell for $75 & $35. i got lucky, both were good and I'm not complaining.

Re: Panasonic TH-P46G10A

Mate. You have been invaluable. I really appreciate the time spent helping me diagnose the faulty parts and linking me to the replacements. Thankyou.

I have gone ahead and ordered. $61.73. Bargain if i say so myself. Id say most people would have scrapped it and bought a new telly. A bit of research and stumbling across the forum has been a stroke of luck. I will get back to you when I receive the parts and get it going.

Shane.

P.S. Know much about receiver ampifiers

not really, got hooked on panasonic plasmas but put a post up with the model and issues. someone is bound to know something.


just remember done my best to diagnose, no guarantees, by all rights those boards should fix it. fingers crossed.

Re: Panasonic TH-P46G10A

Received my replacement boards. Did the resistance test before installing. No good.

SU board - I'm getting a short between ground and the SU2 ribbon connector in 2 places.
Resistance wise nothing is showing between GND AND SU41 pin 2.

SD - There are no shorts between ground and the ribbon connectors. Resistance wise I'm getting 1.081m ohms between GND and SD42 pin 9.

Sc board measure again and is in tolerance.

Help.

[tw2005]

Re: Panasonic TH-P46G10A

Not good news. That supplier is pretty reliable, not infallable I guess. I would send him a message for help and tell him what you've found.

Dead short between gnd and output is never good. When you say resistance wise nothing showing, do you mean 0 ohms or out of range / limits?

[UND312DOG]

Re: Panasonic TH-P46G10A

Multimeter shows 1 when open. When connected between su41 and GND it shows -.000

[tw2005]

Re: Panasonic TH-P46G10A

Ok, so showing dead short at pin 2 and shorted at the outputs. That's what I'd expect on a bad one.

Damn. Only 2 options really, try to get him to send another SU or SU/SD set. ask for it to be checked for shorts at the outputs and pin 2 - gnd.

Or full refund.

returning any faulty part is not really an option, it will cost more in postage than the whole original purchase.

he should be reasonable to deal with, put the issue to him and ask how he'd like to resolve it.

If you can get a board that will save you chasing another supplier and spending more money.

Doubt you'll find another set as cheap.

Always tricky giving someone advice when it goes bad. Used parts, always an element of risk.

See how you go.

Re: Panasonic TH-P46G10A

Yep. I have sent the seller a email. It's just a pain, I have waited 2+ Weeks for the parts to arrive to find they are DOA. Just my luck.

One more thing. Is there anyways to test the SS and A board?

Yeah, I know. Been there too. try ordering 3 boards from UK, DOA, then reorder same boards different supplier. same deal DOA. That killed 6 weeks.

Alternative is refund and pay twice as much locally if MXM still have a set.

personally I think the postage could be better.

Well technically they passed when you did the SC50 jumper and the TV turned on with no blinks.

Although that is no guarantee there can't be an image issue but good chance hey're fine.

What exactly is the concern?

[UND312DOG]

Re: Panasonic TH-P46G10A

Ok. Received the replacement cards today. Just running tests on them at the moment. Both cards are showing no dead shorts between ground and the outputs. Which is good.

I'm running the resistance test on both cards. SD 1.038m ohms and SU 1.052m ohms at their respective test points. A pass is 2.1M ohms. I don't know if it's my meter or not. And I don't want to put them in, in case I damage the TV further.

I think you'll just have to give it a go. 1Meg seems to be a common value you're getting. Far from short and I think even your other board that was not shorted was giving 1 Meg.

[UND312DOG]

Re: Panasonic TH-P46G10A

Yeah I guess so. The good thing is there is no dead shorts to outputs. I'll give it a go shortly. Results shortly.

Re: Panasonic TH-P46G10A

We have picture. You beauty.

I have noticed two black lines running through at the bottom of the screen. I'm guessing a incorrectly seated ribbon on the SD board?
