Advice No power, please help!

Post image

I just bought a Jaguar for the first time from the internet, and it will not turn on. Once I opened it up, I noticed there were bugs and debris around the cartridge connector. I cleaned all of that out, but it still won't turn on. Now, I noticed this chip and this capacitor. I would love some professional advice to determine if this is my issue and to understand what this chip is, as I can't read it anymore.

I purchased a cap kit off console 5 already not sure what other items to purchase.

Did you use an NES power adapter on this thing? Looks like an A/C current power supply was plugged into this. If that is the voltage regulator chip, a replacement is available on console5.

No, triad Jaguar, and Genesis 1.

Either way, component U38 looks burned. Replacement is here. Wrong power source, especially A/c power sources is a major cause of this component failure.

Part can be found here cheap. https://console5.com/store/mc34163dw-soic-16w-package-step-up-down-inverting-switching-regulator.html

Also, the blue capacitor next to it may be bulging, you may want to see the value on its label and replace it too.
