Hi guys I am looking for a service manual for a Denon AVR 4310CI if you have one I sure could use it.
Thanks

Denon AVR 4310CI Service Manual Please

Re: Panasonic sc tnpa5081 rebuild
100% agree on the patents, NDA's
Do you know how I would check the SC board after repaired with a scope before the SU,SD boards were reconnected?
I want to make sure I have the
+5v
VSCAN-F
Vfo
VHIZ
The thing I noticed in the block diagram is when in bypass (SC50 Installed) Q16660, IC16792, IC16793 are not being tested so maybe I have one of these bad?
What really sucks is I don't have a known good set of SU/SD boards so for... -
Re: Panasonic sc tnpa5081 rebuild
You will never find a spec sheet for that part and I would suggest you order a good supply of them.
Here's the quote I received from the Engineer I was working with at Renesas now California Eastern Laboratories...Leave a comment:

Re: Panasonic sc tnpa5081 rebuild
If you take a look at this picture you will see what the SC50 bypass is doing it's providing the VFG to CHA
I don't know why but I have a strange feeling that the SU11/SD11 ribbon cable was not seated right.
If I am right that would mean Q16471 was not turned on and SCNR_PRO would have been shorted to VFG causing it to go BANG. Well that a theory I have probably full of shit but trying to figure it out.
One other thing MAKE SURE you look at PC603 Opto. On the board I am working on before testing the...Leave a comment:

Re: Panasonic sc tnpa5081 rebuild
I ordered from this seller on AliExpress and was very please with the product.
I also ordered some from parts simple here is the US and they were the same exact part I received from China and to top it off I ordered them at the same time and the ones from China arrived a week before the US ones.

Re: Panasonic sc tnpa5081 rebuild
Thanks guys for the input.
Pin 9 on the SC41 connector should be VFG & SD41 connector should be CHA.
The SU board provides the connection to the SD board this connection is through the SU11/SD11 connectors on pin 20
If my assumptions are correct this is what the SC50 connector does when shorted and the SU & SD boards are isolated from the system.
This would explain why the connector needs to be installed during isolation of one or both of the boards.
After...Leave a comment:

Re: Panasonic sc tnpa5081 rebuild
Ya I am going to give it another go but I don't know how many more after that.
Do you know how the SC50 bypass works with just one board removed?...Leave a comment:

Re: Panasonic sc tnpa5081 rebuild
Ok thanks I just need to find another TV to test my work after it's repaired again.
At this point I think the SU board might be bad. If the SU board was bad but not shorted would that still blowup the SC board?
If I isolate the SU board but leave the SD board connected with the SC50 jumper installed would the TV still power up with just the bottom half of the TV working?
Trying to figure this out when the SC50 jumper is installed and the SU / SD boards are removed from the circuit.

Re: Panasonic sc tnpa5081 rebuild
Well guy's really bummed out right now....
I received all the new parts rebuilt the board again went over everything and it looks perfect.
Installed it in the TV power it up with the SU/SD disconnected and it powers up perfect no errors.
Recheck the SU/SD they look good to me with no shorts. Reconnect the SU/SD remove the jumper power the TV on and BANG all kinds of shit blown again!
I don't know what to think at this point either the SU/SD are bad or the screen...Leave a comment:

Re: Panasonic sc tnpa5081 rebuild
If you look at the FGPF4633 IGBT Datasheet it looks like this.
On Characteristics VGE (th) G-E Threshold Voltage IC = 250 A, VCE = VGE 2.4, 3.3, 4.0 V
So it looks like your meter should turn on that IGBT with no problem.
I am beginning to think that if you look at my post #299 where I thought Q608 was the reason Q661 failed after the first repair it was in fact a faulty Q661 and when I replaced it along with the other parts listed I installed a somewhat working Q661 and that is why it worked...Leave a comment:

Re: Panasonic sc tnpa5081 rebuild
This is exactly why resistance measurements are so variable across different DMM's
Fluke 79III
.656 VDC MΩ
1.246 VDC Ω
1.245 VDC KΩ
Fluke 87V
2.776 VDC MΩ
7.31 VDC Ω
7.30 VDC KΩ...Leave a comment:

Re: Panasonic sc tnpa5081 rebuild
Trust me that IGBT is BAD!
All the others turn on just fine with the Fluke 79III
I just tried it with the Fluke 87V and it still does not turn on.
Here are the output voltages in diode mode for the meters measured with the DMM connected to another DMM.
Fluke 79III puts out 2.95 VDC
Fluke 87V puts out 7.30 VDC
Please take a look at the picture I posted in post #325 what do you see?
I think that the IGBT's I received from UTSOURCE are fakes. Look at the...Last edited by dolivas27; 02-05-2016, 03:33 AM.Leave a comment:

Re: Panasonic sc tnpa5081 rebuild
Ok you've talked me in to it I am going to purchase a used Beckman one more meter won't kill me.
I also have one of these on order [URL="http://www.greenlee.com/products/DMM%2540c-TRMS-AC%2540PlusDC%2540cDUALTEMP(DM%2540d830A).html?product_id=17755"]http://www.greenlee.com/products/DMM%2540c-TRMS-AC%2540PlusDC%2540cDUALTEMP(DM%2540d830A).html?product_id=17755[/URL]
I need to put the Fluke 79III back in the Van I needed it today out on a job and forgot I left it on the Tech bench. ...Leave a comment:

Re: Panasonic sc tnpa5081 rebuild
Wow Thanks for all the testing.
Here's the deal not having the same DMM on my side it's hard to test for the same measurements that you're getting.
Here is my testing of the RJP63F4A (Q661) this is using a Fluke 79III DMM.
Emitter = + Lead, Collector = - Lead (Reading = 3.138 M Ω and slowly climbing)
Same IGBT Tested with a Fluke 87V
Emitter = + Lead, Collector = - Lead (Reading = 1.247 M Ω and slowly climbing)
I tested 6 of these and they...Leave a comment:

Re: Panasonic sc tnpa5081 rebuild
Good info thanks here's some more information I have found not sure if you already have this but it does look like the FGPF4633 is a very close match to the 30F125.
It also looks like the 45F128 I have here is just a higher Collector current rating (DC) of the 30F125.
See page 4 for part Numbering

Re: Panasonic sc tnpa5081 rebuild
Thanks not questioning what your saying just trying to make sure I have this right this time.
I believe that your right and maybe I do have a bad one but just trying to prove that it's bad for sure.
If I had a know good one this would not be a problem but it is my belief that all the ones I received from utsource are bad.
They test good in diode mode but with resistance testing they are all over the place and I have no way of knowing for sure what is right or wrong.
Thanks...Leave a comment:

Re: Panasonic sc tnpa5081 rebuild
So you think the new buffers are still bad? They measure out good but I guess anything is possible.
Hope to be ready to test it soon I have went over the complete board and found some other interesting bad parts. I will update later on these.
I don't know what I am going to do about the Q621, Q622 (30F125)
The parts test good out of circuit but after reading everything on the forum you seems to be adamant about them being bad even though they test good in diode mode.

Re: Panasonic sc tnpa5081 rebuild
Not the first time a manufacture has given bad info....
Well that is kind of what I am thinking the dual diodes I installed were only rated at 300V 20A and if I am reading the schematic right there would be more than 300V on the diode especial at turn on.
Well it's either the diode problem or a bad panel as everything else it testing out good.
Also these are listed as two different part numbers I wonder if one is a R and the other is not as one have the leg bent back and the other froward....Last edited by dolivas27; 01-27-2016, 02:46 AM.Leave a comment:
