Panasonic tx-p50ut50b

[jasonr2000]

Hi guys I've got the above to and it wouldn't turn on this morning


Anyway I've taken the rear of the to off and had a look inside I pulled the SS board and I think the problem lies there as it looks like it's got too hot on connector ss52 will attach a pic here it also looks like there is damage to RO51 and the ic's nearby


I'm not sure of the blink sequence yet but will confirm that later


Anyway I can get the board at a reasonable price my question is would any of the others gone as well ?

Thanks

Common failure is SS, 8 blink. Do a bit of a search, there's also a repair bulletin for that board. keep the old board as a core for repair.

Thanks for the reply tw2005


I thought that was the culprit is it easy to fix ? As I can't seem to find the board available now ? I've seen the repair kit which I'm assuming contains the parts to solve the issue

Thanks

I've done some testing with the SS board unplugged the one in question the to fires up and there is a dim image and sound from the tv so it's deffo the SS board now fixing it is the fun part

Hi guys another question

is there anyone on here who can replace the damaged parts for me as my solder skills are not up to it for sure

Re: Panasonic tx-p50ut50b

And another question I've got the tnpa5622 which is for the 42" model of this tv can I remove the needed parts from this board and use them on the tnpa5623 ? As in would they be the same parts ?


Thanks for any help guys it's the only way at the moment I can source the parts as for some reason I can't access shopjimmy.com

maybe. would need to first work out the burnt bits plus replacing the driver IC is probably advisable. You ave both boards so look at the part numbers on the relevant parts. i'd expect they'll be the same.

Someone may be able to swap the bits but they probably won't be able to guarantee it's fixed.

did you notice the burn marks at the earth points on the underside? loose screws? something to pay attention too on reassembly, clean those up and make sure the screws are tight or use a different bolt with a spring and flat washer which is what they used in earlier models. These new screws can be an issue.

Hi Just seen your post,8 blink code with this set is common ,and is almost always the SS TNPA 5623. The board will show Q051 shorted, and can also take its gate resistor / diode/ driver IC .all parts are easy to find on there own or in kits . hope this is of some help Flocko

Re: Panasonic tx-p50ut50b

Thanks to all for the reply and yes there is what looks like burn marks at the top of the board where it mounts to the Tv chassis on the top and the second screw hole down in the old board

The parts are the same as no parts that are bad have the same numbers including the driver ic

Thanks for the url vinceroger69 will see if i can get the kit from them to be on the safe side that this other board the tnpa5622 doesn't let go of its driver ic

Re: Panasonic tx-p50ut50b

Well guys this is now sorted I sourced a referbed board from emos and so far all is good they even threw in the new screws that Panasonic replaced


Still got the old board so will try and source the parts then get that one repaired also

sounds good, can you tell what parts they replaced? new screws is a good choice. I replaced all mine on my 2011 st30 which has the same arcing issue and loose screws.

how expensive was the board?

[jasonr2000]

Re: Panasonic tx-p50ut50b

I'm not sure what parts was replaced they just stated it was a referbished board that had been fully tested and has a 3 month warranty

And it cost me £50 including shipping so I thought that was ok if I can get the other board repaired it will be a back up board in case this one dies

But the screws it came with have washers on them so that must be why they are different

Re: Panasonic tx-p50ut50b

The parts for repair are(1)RF2001 /(1) DG302 /(1)SMD 5.6 resistor/D8696 SOP-8 driver

Hi guys tv has been working fine for more than 10 days now but I've noticed today in a black background that there is green speckles that look like noise not noticeable in any program but noticeable on black bars that show up watching some movies and on dark scenes

Any ideas what this is caused by ??
