Hi I am Vortash it sounds as if the actual fault is in your ballast circuit this is the circuit that fires up the arc on the lamp and sends the signal to the main board that the lamp is running , if this is faulty no signal is received by the board and the lamp light comes on when this happens there is usually still sound but not always as sometimes the problem affects the power supply also .. this is a job for a trained engineer as voltages at the ballast are sometimes in excess of 25000 volts at first arc that then settles to a lower voltage to run ... regards Vortash

Clean the small mirror in front that projects the image onto the rear mirror. The Rear mirror always stays good but the front small mirror gets dusty and the colors and bright levels get affected and appear dim.

There are a few low value 1-watt flameproof resistors in the convergence yoke circuits. They typically range from 1 to 3 ohms. An open resistor will cause the respective color to be non-responsive. Also chack that you have the convergence yokes re-connected to the correct connectors on the board.
