Re: HP Plasma PE0000
None of the caps appear to be swollen. Would it still make sense to replace them?

Re: HP Plasma PE0000
Alastair - I just wanted to clarify, you replaced the 33 and 68uF caps with the 100uF 35v? Or did I misunderstand? I was going to order the caps tonight but wasn't completely sure....

Re: HP Plasma PE0000
Sorry for my ignorance. The SMD caps are the silver caps? So, you are saying instead of trying to solder the joint directly you just heated up the whole cap itself? And a loupe is basically a magnifying glass to confirm you have a solid joint? I'm not completely sure I am following when you say solder a through hole on the SMD pad. I'm sorry but do you mind explaining?
What exactly do these caps do? Same thing as normal caps? Just a surface mount variation?

Re: HP Plasma PE0000
Ok, these are the pieces that I had to resolder. And here they are soldered back on. Not perfect by any stretch but appear to be in there good.
I don't have any of the 100UF v35 just 180UF v35 so I will need to order some of those
Is there a way I can narrow down the problem. Here is a video of what it looks like if this helps any.

Re: HP Plasma PE0000
I will get the caps replaced as mentioned and report back. I think I may have them on hand so probably can do that tonight. Also, I will send a pic of the pieces that fell out tonight just so you know which they are as I am not sure of their names.
If you think that oscilloscope would be beneficial, I will get it ordered. I plan on making this a common use of my time if I can learn enough so I don't think it will go to waste. But, I do not have a clear understanding as to how often an oscilloscope is used or needed either in these cases.

Re: HP Plasma PE0000
Yeah, when the voltage was set it was somewhat pixelated. When turned down it was quite a bit better. I will take a picture of the pieces that fell out but I am certain I have them back in right as the old board I bought from ebay the guy didn't want back and just let me keep it so I was able to use it for a comparison.
I'm not too worried about buying the oscilloscope. I know this TV isn't worth much but, in a weird way I think this is kind of fun trying to learn something new. But, I worry I am going to annoy you all asking questions, hopefully...

Re: HP Plasma PE0000
Ok, in unchartered territory now. I do not have the service manual either but I can try to find something I suppose.
Would this scope work?

Re: HP Plasma PE0000
Where would I find other potential adjustments I could make to see if it would help?

Re: HP Plasma PE0000
My concern is I wonder if I screwed up the Z-SUS board when I heat it up to get the old IPM off. I also had to re-solder a few pieces back on that board that fell off when it was heated. I am fairly certain I got everything on there good though so wouldn't think that would be the issue. I just wonder if there is a way to at least rule this work out one way or another so I know if I did that right or wrong.

Re: HP Plasma PE0000
ya on the VS (187) and VA (65) I have them set. It is very flickery when I have them set to this but figure the adjustment must be somewhere else since these are set correctly.

Re: HP Plasma PE0000
Would it have anything to do with the VR adjustments?

Re: HP Plasma PE0000
I re-used what was on the heat sink which there was a generous amount but it was not new. I can try to rig up some fans or something on it to rule it out for now if you think that would be helpful.

Re: HP Plasma PE0000
Partially true anyway. The static still exists every now and then even when turned down low. One other thing to note, I checked the ZSUS heat sink and it is so hot I can't even touch it after 10 minutes of usage or so, does that seem normal?

Re: HP Plasma PE0000
Ok, I found them. When I turned it up to higher 180's it became more pixelated. When I turned it down to 160's the picture would clear up and not do its static pulsating thing. The only thing I have to test with is an old xbox and when playing a game now it is clear as can be with none of this pulsating. But, when I pause the game it is doing the static pulsating thing (which previously when it was a still picture it didn't do it but when moving it did). Not a huge deal, making progress. Any idea why lowering the recommended voltage is helped somewhat? Worth...

Re: HP Plasma PE0000
How can you tell which is VS? Assuming it's the screws above the power plugs? (pic 3 a few posts ago)

Re: HP Plasma PE0000
OK, looks like TV is set for 187 based on the sticker inside and when I test both VS input's I am getting 177. VA is set for 65 and getting about 64 off of it.

Re: HP Plasma PE0000
I tried to do a little research on this but having trouble locating the VS test location on the power supply. Would it be called anything else?
Here are a few pics if it helps any...

Re: HP Plasma PE0000
Where do I check voltage? I will check the label and post what I find on here but wasn't sure if you wanted me to use the multimeter to check voltage somewhere.
The Y sustain board I haven't touched yet.
