Perfect that will make is less of a hassle for me then since it retains for so long now to see how long

Oh guys  at least someone told exactly what it was or else I might have ended up ruining my set
I am glad to find out it isn't a battery though that holds the time though(even though the cap looks like a big button cell battery

And why would you think anything would ruin your set?

On the 9PG there is a variable capacitor on the systemboard, used with an other capacitor and crystal as clockreference for the date/time-IC.

I have seen where the little battery in computers ruptured from age and ruined the motherboard but since the set down have a battery in it I shouldn't have to worry about it

So take this tid bit of knowledge that you have acquired and then replace the word battery with the word capacitor. Then apply that to your NEC. What is your conclusion?

I have seen both when working on computers but the battery is more common
But I have seen one bad cap (that was leaking)on my nec but I am getting some spare boards so I can repair the one that needs it once I get the spares(it was on a board my friend didn't want to do because he didn't want to risk messing it up)
But I have the nerves and time to do it myself(if not I will see what curts charges to repair it)
Can't wait to get it up and running and off the floor as it is brighter then my Ecp 4101

Ahh, ya kinda missed the point again. The point was, you stated you are concerned about your projector being ruined. However your concern was about a battery leaking and once you found out your NEC does not have one you spouted relief. But, in a NEC, the caps are a more damaging factor, at least 10 fold, then any leaking battery you have ever encountered, yet you seem to want to pacify this as a non projector ruining factor. You seemed concerned about only 1 or 2 boards and ignore the rest. Your comment?

You missed part of my post I had a friend replace all of the caps except the ones on the rear three boards(he didn't want to do them) but I only seen one but I have to test them but may just replace them anyway because of age to prevent any trouble later on
I know caps can ruin stuff they are in if they leak(I mentioned it in my previous post with the motherboards getting ruined)
I think it was on the gain board but I would have to look again
Ps batteries and caps can ruin motherboards in computers seen both(I am a pc repair tech)

In a NEC, especially the 10PG, all caps should be considered bad unless they have been replaced. Forget about visual evidence of a bad leaking cap. You really need to get that out of your head. The concern is not visual leaking but the increasing equivilant series resistance (ESR) of the aging caps. The older electrolytic caps get the higher the ESR. A non leaking cap can be just as bad or worse than a leaker.
Invest some time into this machine and the rewards will be well worth it. I have had a ECP 3100, ECP4500, and M8500. My 10PG blows them all away. The picture is razor sharp with amazing color. If anything it's worth it for the remarkable color accuracy.
Ill get the cap list posted when I get home later.

I could use the cap list since I will have to redo the three rear boards in the set as the rest has been done by my friend but I only seen one cap leaking but haven't had the time to check the rest that aren't leaking but i am going to replace them anyway as soon as I get my spare board to see which one it is that I need to repair(no video or grids)but I at least I don't have to worry about a battery needing replacing
I agree about the picture as I did power it up(to make sure it worked) before I had the caps on the boards replaced(just have to finish the remaining three in the back to be safe(and maybe replace a part on one board)
Just have to find the time in my busy schedule to do it(working on pcs a lot lately but its fun) though I will be glad when I can enjoy my 10pg for sure(and get it off the floor) so I can do some mods I had planned for my Ecp

Yea I forgot to mention that one haha haven't seen one come in where someone did that to it but never know what can happen
One thing I hope never have to take to a computer anytime soon is a hammer(even though I've felt like it a few times(I got some old dead motherboards I may take a day and have some fun DESTROY  and I will bet you will feel like doing that when you get a pc with windows 8(it sucks I know first hand as I beta tested it(almost felt like destroying my beta machine but I have a bit of money in it to destroy it(was cursing for weeks during the beta test(still a beta tester though)

I am a pc tech I have to be funny sometimes 
Anyway the leaking cap is one the output board not the gain board(just looked) but I will recap all three of those boards since my friend did the others(not sure if he did the power supply or not  He didn't say and I didn't ask) but I know he didn't do the video output board the gain board and the video decoder card
I am going to be busy working on this machine this weekend coming up though
I still can't believe this set has two flybacks

So does a Sony VPH 1001-QM, or a Sony VPH 1044-QM... They both have 2 HV transformers and they are right down near the bottom rung...
