LG rear projection convergence issue, can it be fixed without replacing parts?

Hey guys, my bro is having trouble with his tv so I thought I’d ask around online to get some opinions and hopefully some help. Ok so this all started with his rear projection tv, one day it just stopped working. The little red standby light was still on but it wouldn’t power up. If you tried to turn it on it would make the sound it makes when it starts up but then after ten seconds it would make the shutdown sound and that’s it.

So my brother figured it was a power supply issue and found another tv exactly the same with picture issues. He swapped over the power supply board I think it was but when he tried turning it on it blew.

So he sourced a third tv with picture issues. This time we done a little reading and found out it could be the IC’s, so we swapped our original IC board which was fine, with the defective one in the third tv. The picture was still out of whack, but much better than with the other IC board. I managed to get into the service menu in the hopes of finding some sort of value that would alter only the red, green or blue colours but 90% of whats in there is confusing as its not explained and mostly shorthand anyway.

So now we’re not sure what to do next. If we could figure out how to move the edges of each colour in and out our problem would be solved as the middle is fine and the horizontal alignment seems to be good too. Here’s a picture of how it looks at the moment. The blue could do with some clockwise angling too I think. Any ideas????

I'd love to help, but without a make and model, littel can be said. Also, when you attempt to turn the set on, does the standby light blink at all? If so, how many times?
Thanks,
Dan

    At this point, you need to have a complete convergence done. This can only be done with the service manual as there is a specific order in which the adjustments must be made. Search the web for the service manual ($15 or so) and follow the steps for convergence adjustment. That should resolve the issue. Basically, each set has to be adjusted according to the circuit values inside. Because all of the parts have at least a 5% tolerance level, there will be some differences, thus the need for adjustment capability. Using a board from one set in another will show the circuit value differences as you have seen.

Hey guys, I assume you might be having trouble with online games or programs? What you need to do is setup port forwarding.

go to http://www.portforward.com/english/routers/port_forwarding/routerindex.htm

and then select the router make/ model that you own. The next screen will ask you what program your trying to run. Just select that accordingly and you will have an easy walkthrough on how to resolve your problem!

Hoover Premier 706


I have the same washer and the paint started to flake from the bottom of the bowl. Rust under the baked enamel made it lift. I peeled the loose paint then applied rust converter and a zinc paint. This patch is still ok after 12 months but my wife is complaining about paint flakes and rust on some clothes. In my opinion, the only way to remove the agitator is to undo the nuts retaining the shaft from the inside. I guess I will find patches of rust under the agitator and depending on how big and deep they are will determine if I replace the machine or patch the rust.
