I have the same problem... exactly. It lights up for about 2 sec's and then lights out. It's still running but just no display light. Switch it off then on it's lit about 2 sec's.

I have it apart today on my bench and wonder if it could be the lamps but I will scope the power inverter and see if it's running on both outputs.

The inverter switchers look like they run hot as the board is discoloured from heat. It's very possible one of them are fried.

Can they be replaced at all? The construction design somewhat looks engineered not to be replaceable.
