Re: Panasonic 65" VT20 10 blink code

Hey would you be willing to help the guy on gumtree out fix his TV if he posts on this forum? I've told him he can probably fix it with some help from you awesome guys

edit: I've told him to post on this forum so hopefully he perseveres and can be helped out. The more TV's fixed the better I reckon.

You can tell him I have some repaired SC boards I will sell for a fair price.

Re: Panasonic 65" VT20 10 blink code

Can the firmware not be erased and reprogrammed through the service port?

Which port? Never tried, don't have the knowledge or gear but would not surprise me but i don't know where you'll find the info for that.

I was joking about postage for the bezel you pulled off
I know its not worth it. Sorry I have lame humour.


Have you done the firmware mod to lower your black levels on your TV's or is that not something you care about?

No , I'm not into mods, just plain old get it working and keeping it standard

Re: Panasonic 65" VT20 10 blink code

Postage of what?

I'm thinking down the track a bit for the 65"

No manuals will make it hard but essentially if you think of the board as a processor then the only difference between any model is the firmware , data, program loaded on non volatile memory.

some of it is common. So either desolder and swapover or copy the data and overwrite the chips but you'd need a clip.

I've had some fun with a CH341 but the clips supplied are rubbish

Have you done the firmware/eeprom mod to lower your black levels on your TV's or is that not something you care about? The one where you erase the power on hours...

Re: Panasonic 65" VT20 10 blink code

Can you test on the bezel the resistance from the surface of the EMI strip to the frame its stuck to? Does the resistance change if you push harder on the surface of the EMI strip?

not right now, maybe tomorrow evening plus it's screwed together. Time for some zzzzzzzzzzzzzzzz s

Re: Panasonic 65" VT20 10 blink code

And now I'm back to trying to repair the A board on the 65". I've noticed that the voltage on what I believe is pin 10 & 11 on connector A3 kicks in but is not constant and varies from 1-3ish volts when I turn the TV on. Now I'll try the schematics to find where that comes from but reading them is not my strong point..

Re: Panasonic 65" VT20 10 blink code

Not unless I can use one of my arduino boards to program it?

How much for postage?

i guess you don't have an eeprom programmer?

Re: Panasonic 65" VT20 10 blink code

I was thinking the bezel would be? Anyway I'd read what I wanted to read and thought I had 2 birds with 1 stone. The A board for the 65" and the Bezel for the 50" and if that didnt fix it swap parts from the 50" to make the V20 work...

Again sorry for reading it wrong. :0

Funny, I just gutted a smashed V20 and kept the chassis and bezel all because of your crazy problem.

Re: Panasonic 65" VT20 10 blink code

Nothing in the V20 is compatible for VT20 except the Su board , power filter, the speakers and the stand

Re: Panasonic 65" VT20 10 blink code

I never said the V20 board will work. I said there's a nice V20 needing most likely a SC board!

Read what I wrote. I even said 2D!

Haha fair enough. Sorry I read what I wanted to read! (idiot moment)

[tw2005]

Re: Panasonic 65" VT20 10 blink code

Are you sure that the V20 board will work in the VT20?
Does it have the plug for the 3D stuff etc?
He finally agreed on $80 although I'm not sure I want it for that now

Re: Panasonic 65" VT20 10 blink code

yeh he wants $100
I even offered $80 if I could pick it up tonight...

Takes the fun out of fixing them as nobody really seems keen to buy a plasma around here these days. I loved my 50" and thats how this started but they just have no resale value and I dont need heaps of TV's either.

I love them but everyone is on the LED bandwagon these days.

Yeah I think what they do is google the fault. I've posted so much stuff that they'll get a lot of good info that way. Work out it's SC, guess what the TV is worth then take the price of an SC off that.

To fix and sell, no margin there. I paid a $100 for mine but it was 18 months old at the time. Most I've paid is a $100 and the only other was a 50VT30 as it's the top of the line in that series and rare. I've kept the GT340, VT30 plus my original V20(sentimental, first ever decent model I fixed) and a ST30 for a spare.

Someone mentioned OCD
Yeah I love LED, lose one or two LEDs in a string and bye bye $1000 TV.

Generally the plasma panel is pretty robust and most of the issues are SC boards.
