Pioneer PDP-508XDA Y-Sus fault code

[dkneyle]

This TV has been advertised locally. It has a fault code 7 blinks which translates to Y-Sus. Is there a common repairable fault on those boards or is it generally a Y-Sus replacement required situation?
The advertiser also has a PDP-505pg which they say "takes a while to warm up"? What does that usually indicate?
I wonder if the Y-Sus boards are interchangeable?

Boards are not interchangeable. That's 5th gen vs 8th gen.

RED blinks would be power down which could include Y-sus whereas BLUE blinks could be other boards as it is a "shut down".

The Y-buffers are bonded to the panel and are non replaceable, so if the Y-sus has caused damage the TV would be scrap.

8G Kuro is nice but nothing special, 5G is old school.

Thanks Tom. I've offered $50 for the Kuro 8th Gen. He tells me the plasma screen is basically worn out on the 5th gen model. Told him if I pick up one I'll take away the other for him! I'll take a risk on it probably. I have the manual for it Tom (PDP-508XDA) and it's not on your database.

The 5th gen is worth a bit if you get the media receiver and can be fixed by increasing Vsus - Freakaftr8 has a post on this IIRC. I saw a 7th gen 1080p 50" Kuro sell on eBay used for over £335 recently, collection only - that's about $550. They sure hold their value well!

PM me and I'll send you my email address so I can upload the manual.

With the original Y-Drive board I get 7 red blink (Power Down) code and no signs of life. The service manual descripbes this as being a Y-Sus fault. Have changed over with a secondhand board from a (hopefully) reputable seller. The set begins to start up, I get a message on the screen "Powering Up" then drops back into power down failure mode, but now with 5 red blinks code which translates to Y-Drive. Am I missing something? Aren't Y-Sus and Y-Drive the same thing? The block diagram only shows a Y-Drive board in the position where the board is that I swapped over. I'm assuming Y-Sus is integrated into that board.

I feel like some sort of newbie! I don't know why, but I exchanged back the original Y-Sus board with the replacement board and the second time around it's working perfectly. So I must have not pushed a connector home properly or something. Just been running it for awhile with the back off and it's producing a beautiful picture. The 5-red blinks actually translates to the Y-buffers as I read the consistency in the descriptions used in the Pioneer service manual. Maybe I hadn't pushed one of the board interconnects home properly? Anyway, it now looks like I have this magnificient plasma for about $100 ($50 purchase, $50 for the board). Might keep it!
