Hi all,

My Spectrum has an intermittent GI issue. Sometimes some of the GI lamps on my playfield will go off during play. After doing some reading I figure it might be a problem with one of the 2 small auxiliary lamp driver boards on the back of the lamp insert board in the backbox or one of the 2 under the playfield. Does anyone know which lamps each of these little boards control? I can't see this information in the manual.

Thanks, SV

Thanks everyone,
There's 4 boards, two in the backbox and two under the playfield. Does anyone know what each of the 4 boards does specifically?
