Re: Panasonic 50VT30 , Blinking 7 times.
Ow , i am such an idiot!!!
The repair kit came with a small note with positions on the board to be replaced. I just looked at the IGBT's and replaced those with the same name.
Q421/422/433 are not replaced which are short which took out the other ones......
Q421 etc can be replaced with 30F131 , thats how i came up with 6 30F131.
Man , i feel stupid!
I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!

Re: Panasonic 50VT30 , Blinking 7 times.
yeah, it's a shame because I think these are easier to repair than the through hole 5081 boards.Ow , i am such an idiot!!!

So if you still have the original RJP63G4, is that shorted?Comment

Re: Panasonic 50VT30 , Blinking 7 times.
I took all components and the board with me to work. Someone showed me how to measure them and im going to filter all components. I might be Lucky.
After repairing so many tv's i make this dumb mistake. I wanted to fix it to quick i guess

Re: Panasonic 50VT30 , Blinking 7 times.
yeah, I know the feeling. That's why my first repair failed, robbed peter and recycled parts to get one up and bang soon after.
I'm trying to analyse the original fault as it now might be challenging with half repair half shorted plus you said bang and light = not good. generally a flash of light could be some smaller parts exploding.
If the original RJP63G4 and the 30F131 that are located closest to the buffer boards are ok then I'd say original fault was the 30F131 in the middle and the RJP30H2 igbts.
You may get away with using 30F131 for the RJP30H2, I have a board happily running FGD4536 for all 6 , smaller package but no issues yet.
If the parts came out of the cct where it was shorted I'd give them a miss because I had 1 igbt shorted, took that out only, replaced and then the one next to it failed soon after , so I tossed all 3 and put 3 fresh in that bank and that's the board I'm running to see if i got it right 2nd time.Comment

Re: Panasonic 50VT30 , Blinking 7 times.
And now for something completely different, my GT has died again, 6 blink. was fine running for a few hours, was turned off and I just went to fire it up again, 6 blink, no pop but a funny low buzz like a shorted panel, bad buffer maybe?Comment

Re: Panasonic 50VT30 , Blinking 7 times.
Im going to measure all the components when im having my break from work. Original RJP63G4 measures ok in diode mode , no beep.
I might have replaced components that are still good so i'll just replace the shorted IGBT's with the Original good ones haha.I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!Comment

Re: Panasonic 50VT30 , Blinking 7 times.
Ok , measured the components.
Q421 , Q422 , Q423 , D401 , Q401 , Q402 and Q403 are short.
Top IGBT's are all ok. So i replaced the good ones for good ones , so now im 3 short haha.
Must wait for the other parts to come in and then i can fix this tv permanently.I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!Comment

Re: Panasonic 50VT30 , Blinking 7 times.
At work we got soldering iron's from "weller". Removed 6 IGBT's in 15 minutes. Wish i didnt do this repair at home but here at work. So much easier if you have good equipment.I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!Comment

Re: Panasonic 50VT30 , Blinking 7 times.
Replaced all IGBTs and plugged the board back in. Used SC50 jumper and both boards had a green led for a few seconds but it then turned off.
Its now blinking 6 times. I think all RFN20 are bad...but im not sure , do i test these the same as for example Q662?I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!Comment

Re: Panasonic 50VT30 , Blinking 7 times.
I'll search for the data sheet. Any idea's why its blinking 6 times? All IGBT's are ok , no shorts. Im not sure how to test the D401 for example.

Re: Panasonic 50VT30 , Blinking 7 times.
Yes all those IGBT's measured short before i did the repair. Replaced them all for new ones , fired it up with the SC jumper. Panel came on for 1/2 sec and green leds on. Then it shut off to 6 blinks. All parts that i replaced with Q in front of it are still ok.I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!Comment

Hello there,
Google led me again to badcaps when trying to troubleshoot a dying Plasma that is sitting at my uncle's roughly 550 km from where I am. It's an old G20 from 2010 or so, that isn't being actively used so you can consider the panel "not too sollicitated".
Symptoms: TV starts, works for 5-10 minutes, then screen turns black and safety kicks in and spits a 13-blink code with the red LED. Once this code kicks in, the TV will not display any image anymore. Unplug it for a few minutes, plug it again, it'll work then fail a few minutes later.

I know the 6 blinks are a backlighting issue, but when I pulled off the back cover and turn it on, the is a white flash from with the panel then I hear what sounds like a relay trip and the TV goes into the 6 blinking light code. Before I pull all the electronics off and checking the individual strips, there is a on the power board, a harness with 4 wires that run thru the panel, which are what I believe are the LED lines, but Im not a tech so no clue. Wires read OUT 1 + & - and OUT 2 + & - My first inclination was to remove the power board and use my LED tester and go to each + &... -
Hi everyone, I have a Panasonic OLED TV model 55EZ950E, as soon as I turn it on I don't have any image the LED goes from green to red LED blinking every 4 sec, I found the service manual suggests checking OLED PANEL, PB BOARD, T-CON connectors but it seems like everything ok, I didn't find any burns under the pb board
I attach a link to download the service manual, thank you for anyone who can help me

I have the i9 version. I have tried disabling intel and Nvidia graphics in the device manager.
The laptop is just out of warranty.
The laptop continues to freeze randomly with the blinking amber charging light.
What could be possibly wrong with it?
I have also disable armoury crate in bios.
