Technics SA-TX50 in Overload Protection....

I got this unit last year, lights were out and I had a tech put in new lights. I got the unit home and it would go into overload protection. I took it back to the shop and found the tech put in the wrong amp bulbs, instead of replacing they took a bulb out on each side of the VU meters which I was not totally happy about...Anyway, fast forward to a couple of days ago, playing the unit on maybe volume level 3, I paused my music and went outside(I normally turn my stuff when not there). I come back in and it is in overload protection. The VU meters do not light up, could it be the bulbs are acting up and drawing too much power? I found that the fan could be the culprit, I took it out cleaned the connectors and reseated it. I also checked some other connections, the machine looks flawless to my untrained eye when looking inside it.

I would start with checking the main circuit board mine did this as well . Look for 2 3 pin pin packages on the right side close to the front and resolder them also fit heatsinks as they love to hear up and cause dry solder joints .
 
Unfortunately I am not adept at soldering, I would be afraid of ruing the trace, I think that is what is called. I wish there was someone closer to me instrpead of my having to take this to Nashville to get worked on.
