Common issue on these is shorted 5VSTBY diode.
Pictures?
Is this a VESTEL or PROVIEW build? Pictures will reveal that if you are unsure.

Re: Bush 32TV016HD issues

have tried several times to send a picture but it will not up load. I was reading a thread and the TV had the same problem,so I downloaded the power board pictures and it is the same power board, but I cannot find the thread again.

Re: Bush 32TV016HD issues

So, can you see any voltages on the power connector going to the main board, or is it completely dead?

So, can you see any voltages on the power connector going to the main board, or is it completely dead?

To add to that: is there any 5v standby? I know you said you had no voltages, but do you get 0v on the 5v standby, or say 2 or 3 volts?

That pic of the connector is very good! BUT, there are more than one of them on the PSU. Can you get us a picture for each of those other connectors?

Re: Bush 32TV016HD issues

Is compltely dead

[tom66]

Re: Bush 32TV016HD issues

0V on all connectors then??

[keithf2]

Re: Bush 32TV016HD issues

yes

Re: Bush 32TV016HD issues

have you still got voltage across the main capacitor? can you post pictures of the underside of the board as maybe some blown smds.

[keithf2]

Re: Bush 32TV016HD issues

yes voltage across the main capacitor is still there, will post a picture of the underside after tea.

Re: Bush 32TV016HD issues

This is the bottom of the power board, but not that good.
