Hello
In front of me I have an industrial LCD monitor, brand is General Touch PL1501.
It works for a few minutes then starts to make odd colours and behave bad.
I traced it to the chip "TSU16AK" DSP overheats, if I use freeze-spray on it, the operation will be restored a few minutes until it overheats again.
I might think of replacing the entire pcb, if I just could locate it.
I haven't got a clue where to search for this, since it has got no readable numbers on it.
Replacing the chip only might be a solution, but only locate the chip on E-bay (China).
Any advice is appreciated!

I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...
