HP Plasma PE0000

Re: HP Plasma PE0000

Ideally, you'd test those while it's running. If the fuse is blown though, no point, as they'll have precisely zilch across them.
The IPM module on the Z-sus could be bad causing the fuse to be blown.

Re: HP Plasma PE0000

Which is the IPM module? Can I replace just that if that is the case or is that a whole board swap?

[tom66]

Re: HP Plasma PE0000

It's the module under the large heatsink. It is replaceable but the question must be asked "is it worth it?" because it's a lot of work to remove it and I have seen that board for sale for about $35 with the IPM being around $15 to $20.

Re: HP Plasma PE0000

Ok, I will try to replace that fuse and if I have no luck with that then I'll try to find that board for a reasonable price. Ebay the best place to look for that type of stuff?

Re: HP Plasma PE0000

I would not replace The fuse. I have seen time and time again that if in fact is a blown module replacing the fuse can do damage to the other board on the left side

Re: HP Plasma PE0000

Ok, so now the challenge. I'm not able to find a replacement board. I assume this needs to be an identical swap when I replace it? Any ideas as to where I should look for one?

Model 42V6
Board ZSUS
part no 68700ZE013C

thanks!

Re: HP Plasma PE0000

Hmm, I was thinking of PDP42V7, the boards for that are cheap. PDP42V6 is a lot harder to get boards for, except if you can find a cracked model similar to yours and extract the parts.

You might have to go the way of replacing the IPM then. There are services that do this, alternatively, if you feel confident and possess a minimum 65W temperature controlled soldering iron you can try and remove the module. It is bloody hard work though.

The IPM number is usually printed on the side of the big Z-sustain heatsink.

Re: HP Plasma PE0000

Ok, I will check into that. Thank you both for all of your help. I'll probably try to find someone that can solder it for me as I have minimal soldering skill. I'll let you know how it goes. Should I look for the IPM module on ebay once I can determine the model? Or where would be the best place to check?

Thanks again

Re: HP Plasma PE0000

Check this out. Go to ebay type this number in.
331041534694

Looks like it's missing a fuse but it's cheap enough and has a return policy.

Thanks!

Re: HP Plasma PE0000

Replaced the board tonight and replaced the missing fuse in the one I received. The TV acts like it turns on, then turns off and doesn't allow me to power it back on until I pull the power and reset the process. At no point do I get a picture though. Any ideas?

[jasonflippin]

Re: HP Plasma PE0000

Ok, it made a liar out of me. It turned on, here was the display I got. It is still very dim and was splotchy when I first turned it on. Eventually the black splotchiness cleared up and the picture was just very flickery and dim. Here is a picture on startup and then once running. One other thing to note, the heat sink on the Zsus board I replaced still is not getting hot or even remotely warm. I rechecked the fuses for any blown after and none of those have blown. I feel like I'm learning slowly but surely, thanks guys! Anyway I am stuck once again, so looking for some ideas?

[jasonflippin]

Re: HP Plasma PE0000

Anyone?

[freakaftr8]

Re: HP Plasma PE0000

Okay does the picture still look the same with the Z sus disconnected

[jasonflippin]

Re: HP Plasma PE0000

It does not, occasional light spec flicker, but I can never make out anything or see what input I am on. And just to clarify there were 5 connection points I unhooked on the Z sus, 3 white connector plugins and 2 bronze colored ribbons that must connect into the plasma screen itself.

Re: HP Plasma PE0000

What are the heatsinks doing after 15 minutes of running is Z still cold or the Y cold?

[jasonflippin]

Re: HP Plasma PE0000

Z is cold Y gets pretty warm

[freakaftr8]

Re: HP Plasma PE0000

So now either we need a scope to check waveforms from y and z or that z board you ordered may be faulty. I'm betting on that more so. The IPM should be warm to the touch.

If it's the new z board I apologize for.the bum steer. Sometimes people that sell in ebay don't know how to check these boards for proper operation.

[jasonflippin]

Re: HP Plasma PE0000

Oh, no problem at all, it's ebay. No big deal there. Should I bother trying to get a hold of a scope to check the wave forms or work on trying to get the IPM itself replaced? The IPM is underneath the heatsink, correct?

[freakaftr8]

Re: HP Plasma PE0000

Yes it is. Replacing that IPM is a real pain in the ass. Almost not worth it to someone doing it for the first time. There is a real.good chance you could damage the board. Was there a return policy for the board?
