Re: TX-P50G20B with 8 blinks

I believe it is the correct sized screwdriver, it removed the other 3 screws with no problem. I have since tried a few other screwdrivers, I guess i will use some pliers to give it its first turn.

OK I will have a look at the guide now.

Re: TX-P50G20B with 8 blinks

OK thank you guys, I think I am pretty good at soldering as i used to do it for a living (manufacture) but if there are multiple components that may fail i will buy a new one.

1 issue may arise, one of the screws connected to the buffer board was stuck and I didn't risk remove it as it felt I was about to round the head!

Re: TX-P50G20B with 8 blinks



I have just tested this use a multi meter and the results are a follows;

Using the 2000k Ω setting
Pin 1(+) & 3(-) = 002 Ω
Pin 1(-) & 3(+) = 002 Ω
Pin 1(-) & 2(+) = 128 Ω
Pin 1(+) & 2(-) =145 Ω
Pin 2(-) + 3(+) = 136 Ω
pin 2(+) + 3(-) = 145 Ω

I am presuming the pin outs as;
1. Gate
2. Collector
3.Emmiter

either way I think this is not working as its giving me reads from every pin...

HI, have a TX-P50G20B with 8 blinks.

I thought my issue was the SS board but once replaced it still blinks 8 times. However when i remove the SS33 cable of the SS board the Tv blinks 6 times.

A service guide i was kindly provided then shows the next board with an issue may be the A board, but i have since purchased a replacement and this has not cured the issue.

I am guessing the next board would be the SC board but this is not listed as being as issue for 8 blinks?

Is there a way to test the panel to see if it lights up and will work...

Re: Panasonic P50G20E



Hi tw2005, thank you for you response.

When i removed all the above cables the tv did turn on, well the green light came on but the screen was black.

Do you think this now excludes the A board as being the problem? I have replaced the SS board to one i believe is good, so based on the guides you attached most likely failed is 1 SS board, 2 A board and 3 panel! I hope it is not the panel!

Once this has discharged i will have a good look at the cables before plugging them back in....

HI, have a TX-P50G20B with 8 blinks and was wondering if you could guide me to the service manual you were looking at please?
I thought my issue was the SS board but once replaced it still blinks 8 times. However when i remove the SS33 cable of the SS board the Tv blinks 6 times. I think the issue may be the A board and am about to purchase one but would to have a read of the manual to investigate further.
I really hope it is not a filed Panel, out of interest is there a way to text to see if the panel is good before spending...
