Re: Mitsubishi XP-4015c manual?
They are similar, but the PDP-401/402 hour meter commands don't work on the Mits. Its a very basic commercial plasma, with a horrible picture, but just interested in its supported input modes/frequencies, and how to read the hours basically.
Thie Hitachi is a 37 inch XGA panel, pretty different animal but I am looking to buy one if anyone has one!
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Thanks!

Re: Old plasma help.
Still working on this TV a bit. Problem is not in the logic or main boards, and directly related to how hot the set is. Ive discovered that this panel has over 26 thousand hours on it via the service menus.. Pretty impressive if you ask me, but the problem *almost* goes away when the TV is hot, and I _believe_ its the panel itself that gets hot, and not any of the circuit boards, that causes the problem to virtually disappear.
Is it possible that the sparkly sections in dark areas could just be a worn panel? (sparkly only when darker colours are...

Re: Old plasma help.
Similar enough to that. Different form factor....

Re: Old plasma help.
Yes I read that can be done, but I don't believe it can with this board, and if so, there is no info that I can find to enable this test mode....

Re: Old plasma help.
Thanks for the info and assistance up till now.
I had to stop troubleshooting but I had a look through the pdf and saw a spot about troubleshooting and came across “steps of gradients are missing, logic board”. This describes exactly what the picture is doing. Steps of colour/BW gradients are definitely missing.

Re: Old plasma help.
Thats the version I have now, I installed a few days ago.
I found and checked a test point for Ve voltage, and I am under the understanding that this should be somewhere around 100volts? I am only reading 15.6 volts at this point, on the X board....

Re: Old plasma help.
I downloaded the latest firmware from the hitachi site, but it wasn't a version that high. Do you know where I can get that version?
I did find a test point for the Vw voltage on the ysus board, it reads 190 volts, but the sticker states 179.5 volts. No adjustment...

Re: Old plasma help.
I did and they were out a bit but when adjusted to spec it made no difference 😕. The tv has a Vw voltage on a sticker but can't find that anywhere....

Old plasma help.
Hey all.
I have a 42HDT52A Hitachi tank of a plasma. Yes it's old but I have a thing for old plasma TVs.. Lol.
Panel is bright, and colours are nice and sharp, but there's a static or noise on the screen, particularly where the colours are changing brightness. Happens on the menus as well. (See pics). Adjusting the brightness has this weird dithering look to it as well (pic attached) Checked voltages and are ok as far as I can tell. Attached a couple pics. Examined all caps and everything looks ok. This seems to be a well built TV....
