I just purchased a game from another KLOV member. The monitor on the game (a K4906) was not displaying a good image — it was showing significant and rapid "in/out" waviness with both the game board being sold and another board the seller had on hand. His opinion was that it needed a cap kit and filter cap, possibly a voltage regulator. In short, he said that this board had not been serviced while in his possession (I don't know how long that was) and he recommended sending it out. We struck a deal on the game given the monitor condition, so now I have it.
After getting it home, I inspected the chassis a little more closely. I notice a few things:
1. The neck board wire that goes to the strap around the tube/aquadag has previously been cut and wire-nutted back together
2. The flyback says "Made in China" and has a model number sticker MSH1FAP08 on it, the same model sold by APAR for this chassis
3. The caps all "look" fairly new (visually consistent, non-bulging) and are all Nichicon 105c caps, including the filter cap which also matches (visually and in rating) the one APAR sells for this chassis. Visually they match the caps in other kits I have on hand from APAR.
4. The chassis isn't sparking clean, but it's also not "40 years of grime" dirty. I have not yet removed the chassis from the frame to inspect solder or anything yet.
So it *looks* to me like maybe it has been recapped and had the filter cap and fly replaced already.
I haven't had a chance to hook the monitor up to my TPG yet or do any other diagnostics. At this point, I'm just curious if the consensus would be that it probably has already been recapped, or if the above clues don't really mean anything. Or is there any other good way to tell for sure, short of removing and testing each cap? The Made In China fly and the Nichicon 105c caps "seem" like a dead giveaway to me but I'm still pretty new to this stuff…
Thanks!
