Non-working Flash Focus confirms that convergence circuit has failed. If the TV was working normally and colored outlines or 3-d pictures appear, one of the ICs has failed. Check out the Convergence Gallery to confirm your fault.
2 convergence ICs must be replaced, maybe open fuses as well.
This is considerably more difficult than changing batteries or fuses. The deflection printed circuit board must be removed without doing any damage and defective components replaced. Minimum 36 IC pin connections must be de-soldered and re-soldered without damaging the board, nearby components or the ICs. If you have no electronic repair experience, or the correct tools, there is a good chance that the unit will be damaged or secondary problems encountered with remedies that are not obvious.
Many of the STK convergence ICs sold on the Internet are duds (defective from manufacture) or poor quality and fail soon after replacement. The sites that sell them do not care because the cost and bother of shipping is of more value than the cheap parts.
The service manuals for Sony rear projection TVs are available from this (Techlore) site (click on Resources, Service Manuals, above).
Sony rear projection TVs are excellent products when working correctly, far better made than "New Technology" throwaway LCD and Plasma TVs. The biggest disadvantage is that they are difficult to hang on your wall and have no "off-air" HD tuner.
If you have some electronic repair experience and can use an ohmmeter, look at the service manual, get some ICs and try the IC replacement. If you want the TV to work correctly again, get some competent help or specific instruction.
