4 My machine refuses to show any signs of powering up
That breakdown was very helpful in getting the machine apart. Thank you for the great wok in creating and posting. The custom tool for the oval headed screws is readily available now and cost about $10 from ebay or similar.
My machine refuses to show any signs of powering up. It’s not the fuse as I can measure 240V AC making it to the PCBs. So suspecting there is something wrong with the power supply PCB or further down the line. No sign of damaged components - either burnt or capacitors that have blown.
So wondering if anyone has any info on the PCBs. I have found quite detailed repair guides for TVs on youtube but so far nothing for J5s.

@oldturkey03 - thanks for your response and interest. Here’s the PCB images.
They are not easy to get clearly. In some places discoloration that looks like over-heating but it is not that way on the actual PCB.
The closest I’ve found to a circuit diagram of the PIXX-PRD-12 board is on page 4 of this pdf - the one labeled PIXX-PRD-13. It’s not exact however the components (e.g. the diodes and labels) show the same general intent.
Bu iyi bir soru mu?
