53udx10b hitachi rear projection big screen. replaced convergence chips 2 months ago. Worked awesome. Started having power issues 3 weeks ago. Turn on - kicks right back off. Used to be able to turn...

Sounds like the problem started out with an intermittent solder connection possibly on the deflection PWB unless the power relay has a bad connection or is breaking down under load. If it is not the power relay, I would check the connections under the deflection board - paying close attention to the area from T701 and T752 including the Horizontal output Transistor for a short. You also have a possibility of defective filter capacitors causing the problem as well.

Panasonic PT-47WX53 has intermittant convergance issue

I would chack the solder connections at the convergence ICs first. Since the set "recovers" on its own, it suggests a connection issue rather than a defective component. Also, if the ICs were installed without sufficient heat sink compound, this could happen as well. Look at low valued resistors in the area of the ICs for signs of overheating as well.

Keep us posted on your progress.

Intermittently screen move to one side with distrited picture

Might be the convergence chips. Do you have any problem moving the convergence under the menu setting? Convergence chips are reasonably priced. If you know a friend or someone who can solder better than average, I would go this route. My tv wasn't that bad; I wasn't able to set 2 of the 3 colors during convergence setup. Changing the 2 convergence chips did the trick!

Wavy picture

this is caused by a bad convergence module, and there are probably some dried out electrolytic caps in the circuit as well. i have one in the shop right now that came in with the same problem. if you have it serviced, make sure they replace all of the convergence modules (there are usually 2, but sometimes 3 of them), because if one went bad the other(s) is likely to go out soon as well.
