Plain ole user
You likely have an open fuse on the G board.
I don't really understand your questions.Interested in the convergence boards for my kp57ws510 unit? Are yours available or have you sold them on ebay?
$120 with parts, if they are good parts and not junk Chinese knock offs, isn't a bad price. Even if you had to buy parts it probably isn't a bad price though really the amount of bench time replacing the ics will take isn't that long.Yes I also was wondering about locating a "D" convergence board. I do know of a local that will fix it supposedly for about 120$ so I might go that route.
But they are almost impossible to locate. If you do locate anyone who has these "D" board Id be very appreciative to get it on one.
Merry XMAS !
Duly noted. Thank you.Be very careful removing the high voltage wires. It is not uncommon to break the tabs on them and if you don't reinstall them securely you will get arcing which will destroy components.
Huge thanks for the tips Steve. I got the D and G boards replaced and now I have to work with manual convergence. When I got to the screen for convergence I see red, blue, and green crosses in 3's. I have the service manual but it only talks about seeing yellow and white. Did I do something wrong? My TV picture looks like I need 3-D glasses to watch it properly. I knew I would have to go through this phase before things were finished but I'm hoping to squeeze some info out of you ...... LOLHi Shawn, sorry to be slow responding, just been super busy here!
I thought I had pics in the first part of this thread, I'll look in a bit.
It's basically just unhooking the wires - use masking tape to label the wires and I use a sharpie to write on the pcb where I unhook the wire from. I also take a digital pic for EVERY wire I unhook, slow but super helpful for reinstallation! The flip jumpers on the right side of the board just flip up. Look at the service manual to see where the pcb mount screws are at. There's one that likes to hide behind a heat sink over by the flyback transformer.
It's hard to find original chips these days, I've had good luck on three sets now using cheapie chips from Suburban Electronics Wholesale. If you can find originals go for them, if you can't them try the Suburban ones, they must've found a Chinese factory that knows how to make them (Acme used to sell Chinese chips too and theirs worked well also, I'm thinking they were from the same factory).
Don't sweat the hv connectors too much. Just push in and rotate 90 degrees and give a gentle tug. If it disconnected you'll feel it easily, if it didn't just try again. If you break the ears off then PM me as I have a couple extra from sets I scrapped. Really though, just use a gentle tug and you'll be fine.
