Panasonic TCP54V10 7 blinks

[TCP54V10]

As the title says, I have a Panasonic TC-P54V10 with 7 blinks.

I have done some resistance testing on the sc, su and sd boards.
The sc tests good but the su and sd boards test higher (5.5 vs 2.1)? Manual says lower is bad but nothing about if they test higher.

Thoughts on what this could mean and next steps are appreciated.

I have built some pc's but have zero electronics knowledge.

Thanks in advance for your help.

Disconnect the sd/su boards from the SC(3 connectors),

then undo the vfg bolts (gnd bolts that attach these boards to the SC, normally 4 of them)

Then locat a small 2 pin connector SC50, short those 2 pins together.

Now turn the TV on as normal.

if it 7 blinks, SC is faulty, if it passes then it's the Buffer boards

Tw2005, thanks for the reply.

So the high resistance numbers dont mean anything on su and sd?

I tried using a jumper from an ide drive but it would not fit so I tried some tin foil. Would that work as a jumper?

Doing the above it continued with 7 blinks. Assuming it is the sc, any suggestions on where to find one?
They seem to be out of stock at many places.

Thanks for your time

Something that age and size would be a challenge. Google , Ebay, most likely rebuilding your board will be the only option and going by the smaller sizes e.g. 50G10 etc $140 + USD

Search the board number and check the revisions, Quad City Electronics ( bregva (ebay id)) in the US is an example. $120 USD repair service

That's what I was afraid of.
I'll let you know if I'm able to get it going again.

They do TNPA4844 in general, advertise a no suffix version, yours is Rev AE but repair wise will be the same.

Don't get sucked into getting a kit as some are just to help sourcing parts but do not ensure a fix.

search othe models that use TNPA4844 in this forum you may get an idea of what's involved.

I'm on the east coast. Ever heard of or had experience with these guys?

there's a number lurking around and get a lot of their info from here but rarely hear from them. That one I've seen selling bits for a while not so sure about repairs.

truth is some of these have only popped up fairly recently and I know some of the info I've come up with in my TNPA5081 rebuild has helped a few of these, Bregva is one.

it's hard to recommend any but I's probably go with bregva since they are a business and have 100% plus i helped him sort out the TNPA5081.

Maybe haggle the price? or just try Calvin.

ModuslinkPTS was who I would only recommend but they've stopped.

Really you need some local feedback, i only go on what I read here.

by the way I'm in Australia and i do my own boards

That would put you west of our west coast

I'll do some more research and let you know how it works out.

Thanks for your help!
