dead 7020

[digidude]

i have a 7020 that was fine yesterday morning, and dead last night, without doing a thing to it

ive replaces the power supply with another one that i know is good but its still the same

ive disconnected all the HDD etc and nothing, not even a reply when trying to use dreamup

when the power is disconnected, after about 20 seconds the orange display will flash twice, as if the last charge in the power supply fails, this is on both supplies that ive checked and both are fine

so, this tells me something on the main board has packed in

would anyone know where i begin?

cheers for looking

In your good dream measure all the rails of the power supply to main board
and do the same in the bad 7020 and if one of the rails is missing or has a considerable drop then you trace it along till you find the shorted component

unsolder the tuner module....or the LNBp21 controller chip.(huge job)


did you have your LNB cable earthed?

did you have your LNB cable earthed?

the lnb is a quad connected to the 7020, and 800 and a 600, the 800 is connected to an anti surge circuit for the power and the LNB, this then also earths the other 3 receivers connected as well

the mains coming into the property is PME so any earth fault on the mains would have also affected the neutral, and blown all 3 boxes

ill try vest4less suggestion over the weekend as i know the 2 power supplies are both ok

thanks for the help guys
