Hi,

I have a Sony STR-S255 Receiver that has no LCD display or backlights.
The main voltages +12,-12, +57 and -57 volt lines are okay. I have
no schematic presently and I wondered if anyone has seen this problem
that may have a solution.

Any help is appreciated. Thanks.

Does the receiver work otherwise? Is it really an LCD, or is it a VFD,
or LED? Which one it is makes a big difference on how to trouble shoot
it.

Hi Andy,

Yes the receiver works. Tuner selection and amplifier works. Input
selection lights work (tuner,cassette, etc). I can not see the tuner
LCD display and backlights behind LCD display are not illuminated.
There is also a light on the center front panel for the power
amplifier that is not lit either. I believe it should be lit during
normal operation to show the amplifier is on?

Thanks
Roy
