Almost looks like 2 problems.
First run the FCC number at fcc.gov that will give you the
origional make & model number. Then see if anyone put
a manual on the web.
The 2nd pix looks like something in the hoz or HV breaking down.
I have seen FBT's do it & other things. Also could be power supply.
On this one IF you can get a manual start with the power supply
voltages & if you got a scope check for garbage on them.
Other than that poke around, try freeze mist, look for overheating
& cold joints. This will be a challenge........
