Is that related to any caps that I can replace while in there?
If it 'aint broke, don't fix it.
Seriousley, no.....lots of other capacitors you will see when the back is opened, including some bigger D-battery sized ones, but no need to change. It appears the heaviest workload and lifetime hours cap is in the 2 you have to replace -- they must take a big workload when the TV is turned ON/OFF.
I believe that the red sparkles -- which are on my 50" (not visible on the 42" as far as I can tell) -- are related to an electrical discharge on the "Y" board which is alot tougher to fix. It's an adjustment thing, not a replacement thing (unless you replce the whole "Y" board I believe) so I'm just gonna live with it.
Outside of very dark scenes when the TV is first turned on, I can't see the red sparkles except when I get within 5' of the TV (I watch from about 9-10'). The sparkles are also random and separated, mostly on the top, but not grouped in any big 'clumps' so that cuts down on their visibility. But even after the TV has been on a few hours, if I walk right up to the 50" I will see random reds here and there. But again...from where I view, they're invisible. The human eye can't pick out a few dozen red pixels out of 1-2 million when doing normal viewing !!
I've also read that some people have replaced these caps with slightly higher voltage caps (20-25v). Is this still recommended? I want another 4 years out of this without having to open it up again!
You could do that...but I think the 25v are only rated at 8,000 hours. It's a tighter fit. If you go back a while in this thread you'll see some folks did the swap and aside from a tighter fit, no problems.
I wanted everything to go super-smooth...didn't want to change specs that would affect something else and then have to fix THAT......is 8,000 hours vs. 7,000 hours that much ? You're talking about going a few extra months, IMO, tops.
Truthfully, if you get another 4+ years out of the 9631, you'll probably want to replace it at that time, new sets will be so full of features and cheaper by 50% compared to what you paid for a smaller HDTV.
Forgot to mention, I've never soldered a capacitor before, but I am going to try this myself... watched a few youtube clips, and read up on it. Looks straight forward. I have 2 old video cards with bad caps that I'm going to practice with first. I've done some soldering before on electronics, and some plumbing around the house, so fairly comfortable with it. I've never de-soldered before which looks fun. I suppose I'll take some pics and post my results as well. The more results, pictures, experiences, the better as far as I'm concerned.
Look, it's not a super-difficult job and it's not microsurgery...HOWEVER....if you aren't sure you can do it, find a friend who does this or worst case take the circuit board to a local TV repair shop that has a good rep for working with HDTVs and let them do the job. Give them the circuit board and the 2 new caps....probably will take them 15 minutes and they'll charge you $25 or so. Me and my friend actually spent more time taking the back of the 9631 off, removing the circuit board and the cords, and then putting it all back -- compared to the actual unsoldering of the bad caps and soldering in the new ones.
I just recently purchased a bunch of Energy Speakers that I've been dreaming about for years (recently on close-out pricing), much to the dismay of my wife. So when this TV started doing this, it couldn't have been worse timing for my bank account... If I can fix this for $15, I'm a hero!
2 or 4 capacitors should cost less than that...only way it costs more is if you have to have the TV repair shop or an electrician do the job for you. Which again...isn't a bad thing if you're not sure.
Remember to trim the antenae on the new capacitors once they're installed.
