This unit has not only problems with the convergence amps but the digital convergence board as well - this is one I would clearly recommend you take in for servicing as opposed to trying the repair yourself... It could be either that's faulty and some elaborate testing with a scope will confirm the failure.
Also, let the tech know that the correct part number for that digital convergence board is: 23786715 (Pd0078d) and to refer to Toshiba's technical bulletins Tv200301 and Tv200301 for further info. This will save them some grief if it does turn out to be the dc board because the part number in the service manual is not correct.

HOW DO I FIND FIRMWARE UPDATE FOR PS43D490A1 PLEASE


New firmware can't solve colour problems.
For support you can visit this site:
PS43D490A1 SAMSUNG Gulf
(on the bottom of the page they offer an upgrade for USB.
On your own risk, because if there is a problem in the software, trying to update firmware, can disable the computer part completely.

Red and Blue seperate and picture curved toward the middle


You have a hardware problem, you cannot fix it using the menu. in fact you could make it worse.

Try googling DIY convergence repair if you can solder.

If not then call in a pro, about $300

Hitachi Standard T.V.


Some of the problem could be a weak or damaged picture tube - especially if it encountered rough handling in the move. Other possibilities are bad capacitors in the power supply and deflection circuits which are common with this aged set. No adjustments come to mind that could permanently fix these symptoms.
