Panasonic TX-P50G10 ( 7 blinks )

[Moreno83]

Hey guys ,

Im trying to repair this 50 inch panasonic tv with 7 blinks. Already isolated the problem to the sc board with shorted parts. Buffers are ok.

Last week i repaired a 42inch V10 but the panel is bad. Can i use the sc board from a 42inch v10 in a 50inch G10?

It uses the same D board and all wholes and connectors match perfectly.
Anyone have experience with switching sc boards in different sets?

It also uses the same mainboard. Powersupply is almost indentical to the V10.

Vsus on 42V10 is 209V and on the 50G10 is 199V so i might need to play with that IF it works. Im afraid to try it but i got a feeling that it might work?

I thought the G10 would have the larger 4782 board?

Re: Panasonic TX-P50G10 ( 7 blinks )

One things for sure, i don't see the SC connecting to the SD/SU as the connectors are wrong. I don't see any 4844 for 50" size but 4829AB was used in some of the lower models. A 42 " board i would say will be under rated, and mismatched to the panel.

The 4782 comes out of the G10 but it's smaller then the board thats in the tv right now.

I have not connected the cables to the buffers yet but they fit perfectly. The board is also used in 50 inch models but not the G10 so im not sure if it will work or not.

Whats the worst thing that can happen besides shorting the parts?

Re: Panasonic TX-P50G10 ( 7 blinks )

You are right TW2005 , the connectors dont fit. Did not look close enough.

I'll swap the shorted parts from the working board to the defective 4782 to repair this tv.

Not an easy board to do, have you done one before?

There can be a lot of parts needed to repair these, some that are getting hard to find (2SJ281/RJK6026/2PG011/RJP6065/45G127+SMD drivers, resistors,diodes) I would go with a replacement board,definitely not an easy repair as TW has said.I do not think the TNPA4829 will help with donor parts, best to keep that as a working board for when its needed

Apart from the P FET I don't think I used a single original part. A lot of bits I used were from doing the 5081. RJP63F3 is fine for the 6065, The RJK6026 is just a FET so plenty to choose there, 45G128 for the 127 and the FET driver IC 737 was also suitable as a swap. You could use a DG501 or 502 for the 2PG011 but I had none of those blown.

some of the subs listed are also getting hard to find in TO-220F. and I would not mix and match any that are grouped or paired( one 2PG011 +DG501/2)as these need to be matched

Re: Panasonic TX-P50G10 ( 7 blinks )

Thanksfor the replies guys!

@TW2005 , no i have not repaired any of these older y-sus boards yet. I did order ALL parts in bulk for the board you repaired. I got a few of these boards , they were thrown in the bin by a tv company and i took them out

Well i must say , it takes alot of time to desolder the parts and replacing the board is not optional , they are too pricey.
I think i am going to repair the board myself , its just for the hobbie and i got all the time.

Re: Panasonic TX-P50G10 ( 7 blinks )

Currently replacing parts on the shorted board.

Replaced 2PG011 for DG502LW

Can i replace 30G123 for 30F123?

Also , will RF2001 also work for any of the parts on this board? TNPA4782

?

you mean with?

502 is fine for pg011 but like flocko said you'll have to replace all in the bank as they are parallel

30F for 30G, F is lower voltage rating than G

RF2001 on its own does not tell us what voltage or type of diode , it's 20A that's all I can tell

sounds like this board has a lot of different parts failed than what mine had

Re: Panasonic TX-P50G10 ( 7 blinks )

GT30F123 =300v 200A GT30G123 =430v 200A RF2001= 350V 20A dual diode hope this helps. As i said in my last post, with these board you can expect to replace a lot of parts and if you fail to pickup on any,and fire the board up,you will be back to the start replacing them again, that was why I said get a replacement board. but let us know how you get on and good luck

Re: Panasonic TX-P50G10 ( 7 blinks )

Thanks for the replies.

What i meant was; Can i use the 30F123 for the 30G123? Just to power it up and see if the board works.

About 10 or 12 parts have failed. Will list them when i get home.
