insignia ns- pdp32-09 no power

[CR Designs]

Hello, picked this up a why back. first time working on a plasma, This tv is dead no power . checked voltage on PSU get no readings at all. fuses all check out to be good.unplugged every thing on PSU no voltage.also caps look good. hope you can help.

Check standby diode. Check any fusible resistors.

Check standby diode. Check any fusible resistors.

I had checked all the diodes they were good. To make sure which one is standby diode ?

Re: insignia ns- pdp32-09 no power

It will be near the standby transformer, which is the smallest one on the board.

Check standby diode. Check any fusible resistors.

Standby dicde read .1 one way and .378 the other way

Check standby diode. Check any fusible resistors.

These 2 resistors read .1 both ways see picture they are circled

OK, check voltage across the small (<100uF <50V) capacitors on the primary side of the power supply. Something is going to be missing.

I found 3 of them all read .0 volts

OK, can you get a whole or split pictures of the top and bottom of the power board?

I checked the small caps again 3 of them were testing at 0.01 and 0.02. the forth one tested 0.00

Here's pictures of power board

Re: insignia ns- pdp32-09 no power

For future reference, bottom refers to the other side of the PCB. Can you get one of the other side?

OK, check resistance between pins 4 and 6.

How are you numbering pins ?
1 8
2 7
3 6
4 5

Read pin 4 pin t0 6 pin = .1

Re: insignia ns- pdp32-09 no power

0.1 ohms, or single "1" meaning infinite/over-range?
