How long do Cap Kits last? Looks like my Nintendo already had one?

[CitznFish]

I have a Nintendo Popeye and I am currently putting in a "cap kit" on this monitor. This is my first attempt. I successfully discharged the monitor and it's now in pieces with the board exposed. It's very apparent that someone else installed a cap kit, but I don't know how long ago. The board is discolored  where each capacitor was previously replaced. I have replaced one capacitor already, but I don't know if I should continue. How long do these cap kits last? I have no way of knowing when the originals were replaced. The capacitors they used do seem a bit larger than the ones I received, so maybe it's an old job?

The reason I am doing a cap kit is because the game plays, has sound, but no picture. I have turned brightness up all the  way and the picture is still black.

I guess i can't do any harm replacing all the caps again, except this is my first time soldering. I am using a 15w iron and a solder vacuum that works pretty poorly.

Also, I did check the fuses and I have replaced the power supply.

Looking for advice. Thanks!

Sounds like you may have a more serious problem than a cap kit will fix (although it won't hurt to do it now that its out of the game) is there any glow on the neck when you power it up? what have you done so far as far as trouble shooting goes?

the neck did have a glow, and the neck board appears to be in good shape. I have replaced the power supply but I'm unsure if the monitor was receiving the correct voltage. I don't know how to check the voltage either. (Where to read it)  I have turned the brightness up all the way and that didn't seem do anything.  I'll finish the cap kil today and see what happens next. Maybe the flyback is bad? Not sure what that is but that was suggested to me before.

if you crank up the brightness on the flyback you should see a white screen with greenish lines retraced on it (assuming the tube is getting power) if not, i would think it may just be dead--you'd have to get randy fromm's flow chart for your monitro and follow it along to test for voltages at certain points--great way to isolate your probs.

there is no flow chart for a Sanyo monitor AFAIK.

woohoo! I completed my first cap kit today. I started with 4 caps replaced 2 weeks ago then never had time to go back to it. Today i replaced 18 others and it went pretty fast and was pretty simple. I had never soldered before so this was completely new to me. Took me 4.5 hours to remove/replace all the capacitors and reassemble the monitor.

Most shocking of all, it worked! beautiful, perfect picture! Now I won't be so gun shy when it comes time to do the next one.

FWIW, I learned one thing, solder suckers are a waste of money, and solder braid is your friend.
