Nice !!

[winni]

THX.
Your Chassis ist definitly faulty, the power-supply is dead.
There is an integrated circuit, that does the switching job, i think, that is defective.
I will order this part..... and then we know more about this.

Oké, good that you found the problem.
Maybe it is a good idea when you find parts from withs you know will break down easy when a board gets old and the price for these parts is not that high to changes these parts aswell to make the board more future proof.

I have to examine the cause of the breakdown. Dont want to kill the new ic, i ordered it today in the city that never sleeps... .... HK
May take few weeks until it arrives, but i ordered in foresight five pieces! One for the rep, the second, if i make any mistake and the rest for my storage!
Found a totally bad capacitor at the sense-line of the switchmode-ic. And a broken transistor in the startup-circuit.
i will try to repair the periphery round this ic.
And in the meantime your signal connection cable will get a suitable plug. Its not good style to solder such a cable directly at the pins of the pcb.
Sorry for the delay, but i only will do a good job at really fair price.
Regards
Winfried

Surprise!
It works. The ic is in good condition, the periphery was faulty, only. I replaced the startup transistor and the power supply fired up!
The second fault was a strange moiree in the picture, there was a ripple on the 12V rail. The belonging Cap was bad, after change the picture was good.
After half a hour test run the contrast flickered and introduced me to a new problem. Arghhhh, why i have everytime the same blues with different faults at the same set!?!
Also i fixed it by soldering the video-processor-ic. it was sensitiv to vibration.
Now it runs since above two hours, tomorrow i will pack it and send it on the way back.
The signal cable is also repaired.
