The information has not changed, I stated initially that it has an 'auto-reboot problem'. The error code is meaningless as that could be quite a lot of things. As for sending it off, it doesn't make sense. The additional receivers were picked up for a few pounds just for parts. The technology is old. I thought rather then buy another receiver I'd try to fix it. I've had it in the re-boot state for a couple of years, it's been sitting around.

But I take your comments onboard.

Ok, that is fine, had i known it had an error code, I would have taken a slightly different tack. sometimes like on cars they mean something, other times you will never find out the meaning.
I do suspect that the resistor you replaced may be of the wrong value. take the opto coupler marked PC3 and ic2 from one of the other boards, replace opto coupler pc2 on the psu you are working on with the one you've just taken from the other board and also replace ic2 and change the resistor to 6.8k ohms. whilst the parts are off the board, have a check of the resistor values, (check them all by lifting one leg off the board, check the all the diodes including all the little zener diodes. If your meter has a diode check function, if not, use the ohms x10 or x100 ranges to show up a reverse leakage. Then without an esr meter to test with, replace the capacitors, I have a boxfull that look fine but have high esr, low capacitance.Good luck and keep us informed.

Will keep you informed, many thanks. Might take a few days. Solders and me are not compatible. So the slower I go the better.

 

Hi Guys

Update, soldering gun had to go back was faulty. Ordered another, in the meantime:

Of the three receivers,

a) The original - receiver auto reboots, melted resistor. I think it's a red herring, I think there is an issue with the main unit, although it produces a good picture.

b) Parts receiver 1 - PSU - has had liquid / food spilled in it (also melted receiver). The receiver produces a slight grainy picture, but random flashes of pixilation that last barely a second.

c) Parts receiver 2 - PSU - melted resistor, again I think it's a red herring, I think there is an issue with the main unit. The receiver produces a very grainy picture, random flashes of pixilation that last seconds.

I took the main unit from Parts receiver 1 and used the PSU from Parts receiver 2, no autoboot problem, but slightly grainy picture, but random flashes of pixilation that last seconds.
