Mitsubishi WD-52725

My TV has the timer/power light flashing a continuous fast green.  When I hit the system reset button it begins the same flashing pattern.  My dealer said I needed a new bulb and I installed it and it did not effect the flashing light.  The bulb was the original from 1995.  I have seen other questions on this in the blogs and they mentioned changing out some capacators.  Can you give me insight on this problem?
