You're absolutely right. If you look at the wiring diagram on the machine it is clear that the drain pump is powered by triac on PCB (part code C00270972).
I think it is definitely safer and probably cheaper to replace than to repair the PCB.
It is always a good practice to visually inspect PCBs that there are no visible defects such burnt out elements, etc. before replacing. Sometimes the reason for burnout PCB may be on a completely different side.
if it does not go all the way across the screen, may be the buffer board controlling that area. you can usually visually check for burnt/overheated parts, then replace that particular buffer. could also be X or Y sustain PCB depending on whether it is vertical or horizontal.Again, you might do a visual for burnt/overheated parts on the particular PCB & replace either parts or PCB.
Lastly , may be panel....not cost effective.
Gateway MA7s have dodgy DC sockets. Poor solder joint on +ve pin = increased resistance = lots of heat = burnt PCB around +ve pin usually shorting the +ve pin straight to ground. If you're lucky you might still be at the poor solder joint stage and the DC socket might simply need replacing and/or re-soldering. If not, it could be a burnt PCB and it's a pain to bypass the burnt areas due to how the power gets distributed around the PCB.
Hi Mate, I have the exact same problem, casued by wrong adaptor being connected by accident, did you manage to find what the code is on the IC5 chip ?, I can see NSV, but there is another letter or number before it but cant make it out as that where its burnt.
