Re: Techwood 32884HD flashing blue orange

PL800 and PL803 not fitted to board

Re: Techwood 32884HD flashing blue orange

PL805 connector to main board all voltages seem to be ok 12v @11, 5v @17 19 21 etc.

If you don't give all the voltages for every pin then the fault could be missed.

Re: Techwood 32884HD flashing blue orange

that mainboard for sale on ebay is where i got the power board from

Re: Techwood 32884HD flashing blue orange

do you want every pin reading

Re: Techwood 32884HD flashing blue orange

every pin reading is the best idea we can see what the voltage it is what that pin does etc

Re: Techwood 32884HD flashing blue orange

I think this is the main board manual

[london-freddie]

Re: Techwood 32884HD flashing blue orange

PL805 conector to mainboard
pin 11 11.6v, 15 5.2v, 17 5.2v, 19 5.2v, 21 5.2v
pin 10 3.4v, 12 11.6v, 14 5.2v, 16 5.2v, 18 3.4v, 20 3.4v, 22 3.4v
if that makes sense other pins showing no voltages grounds etc.

Re: Techwood 32884HD flashing blue orange

Here are you readings. It looks as though the backlights are not coming on since all the other supplies appear to be as expected.

Can you lift Pin 8 of PL805 out of the connector and connect a 1K resistor from pin 8 to pin 17 and see if they come on.

Main board firmware fault. Try running the core update folder Via usb see if it fixes it.

Re: Techwood 32884HD flashing blue orange

I was afraid you were going to say that but just checking every possibility first

Re: Techwood 32884HD flashing blue orange

The 17mb82 core update will work if not the 17mb62 update will also work. Check good for it.
