Hello guys, I just got one 636 receiver with the same behaviour and I would like to ask if anyone saw this type of repair, looks like the repair was done by someone who knew very well what's there, probably service centre. I've attached one picture with the board. Thank's in advance.  I have seen many of them like that. The factory must have had a production problem and installed the jumpers. I don't believe that is your power problem. Does your receiver power up at all or is it dead? I have repaired hundreds of these now and this unit was the only one with a bad power transformer. ( Still have not ordered the parts for it I will some day!!!! HAH LOL ) |

Hi, there is only this continuous relay click. I've disconnected all the cables and left only the HDMI board connected to the small power supply and it behaves the same, clicks.

Give me a couple hours and I will look into this.

Explain to me what you mean by continuous relay click.

Hi mastertech, I've uploaded one video:
It seems to be the same behavior described in this topic, I've followed some corrective actions:
- with Q7016 removed the voltage is pulsing
- attached one jumper wire between pins 1(mpowerd) and 3(gnd)of P901A and the relay (RL9001) latch.
- steady voltage on Q7013
next should I remove R7035?

I am not seeing where you are trying to go with this. What voltage is fluctuating?
