The picture separates into the blue and red images. is this worth repairing? can I repair it myself?

Yes you can repair it yourself if you know how to unsolder and solder IC's
The two large Ic's in your convergence Circuit has failed. You will need to replace both of them to return to normal viewing, Also the unit may need a convergence alignment after repair to insure picture quality.
Your tv's menu should have a user convergence alignment option in the setup option, but for factory quality have a technician do a factory mode alignment. Replaced both IC's with part#'s STK-392-120

Hope this helps you:
Please leave comment for futher assistance.
Thanks Lavell

Samsung HC-P4752W 47 in. Rear Projection bigscreen TV

You dont have to remove the aluminum heat sink. The ICs are attached with screws and then just unsolder the ICs from the circuit board and then replace the new ics into the pin hole locations after applying heat sink compound onto the back then screww the new ICs to the heat sinks then solder the pins. Very easy repair.

Mitsubishi VS-5006R picture Ghosting

Since the problem corrected itself initially, it may just be poor solder connections. Try resoldering the pins on the convergence ICs. These are large black ICs attached to a heatsink and should be marked STKxxx. If resoldering does not resolve the problem, replace the ICs.

Hitachi 50ux57b

The green and blue ghosting is a convergence problem that is either bad connections at the convergence ICs or defective ICs. If you can solder, try resoldering the ICs. If that fails to resolve the problem, replace them. These ICs are large black ICs attached to a heatsink. They should be marked STKxxx.
Keep us posted.

1.5 days after replacing both IC chips the blue started ghosting again and then...

The biggest problem you stated yourself. You bought aftermarket type IC's. You should have been smarter and purchased the correct IC's for the set. All IC's are not alike, even with the same number on them. Aftermarket IC's are just that. Built in China or are factory rejects. You might get away with replacing the iC's again from a reliable dealer or you might have messed up the power supply in the meantime. Good Luck
