backlights in tp.vst59s.pc815

[as1jc]

can some kind soul tell me how the back light circuit is controlled in this universal combination board. i'm new at this but i know how to use a meter.its almost impossible to work out this circuit tracing solder runs on double sided board. i have figured out that the backlight output is what APPEARS to be a rectified ac output from a transformer.what feeds and controls the input is a mystery.any responses are welcome

You need to give more details and pictures so we can see what we are dealing with.
