I'm trying to repair a Gemini 620 dual CD Player...Each LCD display has three very small (grain of wheat?) bulbs per side, wired to a very small circuit board. Schematic says they are 7volt, 42ma. They are soldered with wire leads, and in parallel. Measuring with meter I'm seeing a little over 7volts at the beginning of the little circuit. I can't seem to find a match of the bulbs...Any ideas? I think the circuit has a power regulator (?) and a diode. I thought about going my sometimes typical "jackleg" route and just wire in a wallwart supply and change bulbs, but other than being a less than optimum solution, I'm concerned that wrong size could be too hot inside that small display...
