panasonic led 32- no standby power no led?

[simon.ribeiro]

hi i have a panasonic led 32 tx-32c300e that has no sign of life no power and no standby led,

it has the following power supply board tnpa5364 ad 3p

i am guessing that the power supply is broken but i need help with diagnosis.

at TP7502 i have 0 v should be 5.7v

i dont know how to follow the diagram to find the fault

Re: panasonic led 32- no standby power no led?

On some Panasonics they do not turn on the STBY LED when the TV is off. So the TV is off, the LED on front is off also.

Based on what you are describing, either you have no STBY voltage on the power supply, or the main board isn't telling the power supply to turn on.

This is a Vestel set ? Upload some images of the boards please.

Re: panasonic led 32- no standby power no led?

not sure what a vestel set is?

Re: panasonic led 32- no standby power no led?

Its a set not built by Panasonic and uses Vestel boards/chassis. You confused me as the model of your Tv is built by Vestel according to google but you say it has a Panasonic Psu ??? Got images of the board ?

Vestel = Totally shitty Turkish maker of TV Garbage popular for the big names to re-badge in Europe....

Seeing it has a 'TNPA' part-number, I'm guessing genuine Pan.

Vestel had patent right in EU, and its not bad as you think, patent are for main board not PSU or T-CON those both Taiwanese ( Chinese maker )

sorry for delay

Sorry to disagree, but there's loads of engineers that also think Vestel = utter Crap--whether they have patents on their turds is meaningless!!

You can patent practically anything, just makes it harder for other Co's to copy--But Who in their right minds would copy a turd!!
