Pioneer Kuro Pro 111FD 8 red blink error

Pioneer Kuro Pro 111FD 8 blink red LED.





I have been trying to solve the power-down 8-blink red LED problem with my Pioneer.


So far I have replaced the power supply board, and the digital assembly board, I have reconnected the ribbons to all boards, ensuring the connections are good. Even though the problem is the 8 red light error and not the more common 8 blue light error code, I had Kcrownie,
based in North Carolina replace the chips that cause the 8 blue LED problem (the main board and audio board) the plasma is still powering on for two seconds, where I can see the picture on the front panel, and then it shuts down with the 8 blinking red LED mode? I will put my original boards back in then put in a new main board and see if the main board was the problem.
Seeing the panel come on for two seconds and then turn off is so frustrating. I have not put in a new main board but will check my Ysustain board for issues. I came across some good information here at Badcaps, a member going by tom66, had a lot of knowledge on these pioneers. I love my FD111 and missed it so much for the last 9 months I bought a used 151FD a week after she went out so at least I have a backup. I feel confident I can fix the 111.

Code error 8 - replace 1.8v regulator....

Lotas, thanks for replying to my post, this fix that you have sent is for the 8-blink BLUE led. My regulator checked out okay so this is not the problem. A deeper dive into the boards will reveal the culprit I hope.

When the screen does come on do you see any black lines either vertical or horizontal?

No black lines either vertical or horizontal. I see the screen come up with HDMI top left with pillar box sides and a black center screen for 1 to 2 seconds then the power down followed by a red light error code eight blinks then repeat.
I have tested the VSUS and VADR on power up on the power supply and that is normal when the plasma fires up then the voltage drops as the power down happens. I think it's a bad cap or fets on the YS board or maybe the main board.

I will buy a Y Main Board I found in Canada, but for the practice, I want to pull out my Y Board and replace the Capacitors and MOSFETs. Where would I find these caps and fets? In the pictures I have posted, the blue capacitors are from my main power supply.
All the other pictures with the brown Capacitors and MOSFETs are on my Y main board. I live in Los Angeles California.

I have tried so much to repair the Pioneer Pro 111FD, but from what I have found my panel may be unrepairable. The best description I found anywhere of what I was experiencing with my Panel was this:

I found this here on Bafdcaps.

I was ready to put my Pioneer Plasma back together and call it quits. I thought I would put the original Y Drive board back in before I put the plasma away and I thought to look at the solder connections on both boards one more time. I looked at the points where the Y board connects to the Buffer boards and where the ribbon connector from the digital address board connects to the Y board. I was confused and shocked as on both boards there seemed to be missing solder. I will post the picture and maybe someone can chime in on if these are bad points of connection.

I was able to see a missing part of the screen when the plasma powered up for a second, It looks like a bit of a vertical missing image.

Thanks for your time.

The unit is a Pioneer Pro 111FD from 2009 I was getting the error red blink 8 times gave me these areas to look at.
