Hi folks, need power supply schematic for Normende N263LD also used in N3202LB, power supply type is JSK4180-024A, have three with the same fault, on switch on blue led lights but set stays in standby, no 5V, 12V or 24V, just standby. I don't have the sets just the PSU's, I have been sent them by a fellow service department.

Hi Frank,
Not met one yet, but what lights the blue led if not the s/by supply ? gives me a duff-Eeprom feeling - all the best - Chris.

I haven't been able to test them yet till maybe mid next week, was after studying the circuit first (layed off at the mo), the shop that sent them to said the fault is as follows "On switch on the Blue led comes on and not the normal red led first, and the TV does nothing as all other voltages are down".
To me the always 5V standby is working but the main power doesn't start up, I have never seen these sets before, and I have only been sent the power supplies. This chap was the oficial service depo for the make locally, but he only works at panel changing level and not component fault finding, unless the fault (like bulgy caps) stands out, and he's willing to pay a fair price to have them repaired. All three he say's have the same fault, so it must be a "stock fault", are they still called this way?? I'll post all findings here.
