I decided to take it apart

Everything went nice. There's no more plastic box replacing the actual battery. I have only a straight piece of plastic held in 2 screws. Guess their cutting their costs.
Power button went out nicely.
I attached some pictures of some components and issues I found inside.
I noticed a funny wire on the bnc connectors board so I decided to disassemble everything. There's no fan inside the 6062!
Aflter I got everything out I saw what that wire was. It seems they decided to make another connection inside, they disconnected one resistor near the 1khz source and instead of grounding it they routed the connection to another place via that wire, finally the connection goes into a chip. Also where they patched the other end near the chip...that connection was going to a via near the USB connector. They broke the connection to that via as well. I noted it in the photo. I don't know why they did this. Maybe a design error or they decided that this is better? That resistor is 1k and comes of that regulator or whatever that is near the 1khz source.
Then there's the adapter board connector, seems like some solder is missing on the top part, but on the bottom everything seems ok. Also that connector doesn't go all into the other board. it's partially in but I measured and there's electrical connection from one side to the other. I haven't found anything obvious apart from that wire.
Also I'd like to know what are the exact voltages that I should find on the PS conenctor? I found in order GND / GND / 8.48VDC / 8.48VDC / -7.86VDC / GND / 8.6VDC / 1.77VAC. There was an offset of 2.2mV between first grounds and the third.
The only "mystery" would be the metal plate that sits on top of the BNC board (not the one on the back). It's a very tight squeeze and it has a plastic sheet coming out, I presume to provide electrical shield between the metal shield and the electronics inside. It's not quite centered as well and it's soldered so I did not touch it. I could void my warrany this way and I just got a broken scope

After I partially assembled it I decided to start it up and see what's happening. Maybe if I wiggle some parts it will work. Started right up and I had the probe connected to the 1khz source and it seemed smooth. The waveform was on screen and the trigger button was green. I decided to start the calibration once more and hurray! it worked, in a few seconds it made the whole adjustment. After maximum one minute of playing with the knobs the red light appeared on the Run/Stop button and nothing worked again. It froze again when I selected the self calibration... So it seems that it's either a thermal character or something is not touching right. I didn't screw anything tight. I will try to play some more maybe I find the problem. I will put a fan to blow inside, maybe that would help as well. Any more ideas?

I forgot to mention that when the scope is not working there's red light usually on the Run/Stop button. If I press it it goes red again instantly. When it worked that button was green.
