Re: Onei 26av400

Mkay, looking at schematic:

that diode should NOT appear open...

That would cause loss of 24V audio supply. I can't be certain if that would just cause lost audio or other problems.

Check across C931, C961 and C962 for 24V.

Re: Onei 26av400

Thanks tom,how do i check them c931.c961.c962

[tom66]

Re: Onei 26av400

Check the voltage across them, expect 24V.

Re: Onei 26av400

The same way i checked the diodes with the multimeter

Re: Onei 26av400

No, use the DC voltage scale this time like you check a battery.

Re: Onei 26av400

with the setting to v-
so if the cap is 1000uf switch to 1000 ?

Re: Onei 26av400

also can not seem to locate c931

Re: Onei 26av400

ignore the c931 quote

Re: Onei 26av400

c931.c961.c962 all been changed and still the same problem

[tom66]

Re: Onei 26av400

You did not need to replace them. I asked for the voltage across them.

Re: Onei 26av400

fair enough,so what could i check next tom and i like your help.

[tom66]

Re: Onei 26av400

I asked for the voltage across them. With a multimeter.

Re: Onei 26av400

i did test the three and was not getting any readings,so i changed them

[tom66]

Re: Onei 26av400

That was not necessary. Lots of things can cause that. When plugged in though, TV should do a self test. So hold meter across leads, plug TV in, see reading.

Re: Onei 26av400

so what have i got to test now ? can you explain why the power/standby light will flash even when the power is pulled.

[tom66]

Re: Onei 26av400

Hold meter across leads of one of those caps, plug TV in, see if reading spikes.
TV has capacitor that stores charge, like battery, when unplugged. So it will run for some time with no power.

Re: Onei 26av400

just the one ? or test all three,could i ask what to select the multimeter to.

[tom66]

Re: Onei 26av400

Pick your favourite, they will all be the same.

Re: Onei 26av400

ok so basically place both leads on cap and see if it holds a reading or drops etc
