Default PSU - contact points in the ballast ?

I may have a faulty psu on my projector. I can`t hear any attempt at striking the lamp.
I`ve read that the contact points are one of the few user serviceable items on the psu.

Please could someone point out to me where this unit is located, and help with any info on adjusting the electrodes.

many thanks.

I'm guessing what you read is about the contacts that touch aginst the contacts of the bulb? if they get oxidised there will be a poor connection or none at all.

I hope this helps.
