HP ENVY DV6 Died?

[Dudefoxlive]

Hi, i was given an HP ENVY DV6-7229WM by some friends. They claim to have found it at a dump and there were signs that it was either somewhere around there or in a really dirty location. Either way i believe there was liquid introduced to the machine at some point in its life but it was not a lot. Recently (Last night as of writing this) i was playing Roblox on it and it randomly shutoff. I noticed it was quite hot to i let it rest while i went and ate dinner. About an hour later i come back to the machine STILL not turning on. at that point i started to take it apart and see if i could spot any visible damage either from the liquid or from heat or anything at all. Well surprise i found nothing that looked bad. I reseated the CPU but still nothing. At this point i decided to look away at my iPad as i was talking with some friends on discord on it and when i looked back the laptop had turned it self on. At that point i was happy but i did not get a screen because there was no ram installed. Well after installing the RAM and powering back on i still did not get anything. After awhile of testing i decided to plug in the speakers to see if i could get some beep codes or something. Well i got nothing. I know some HP Keyboards will blink the Caps Lock light to let the user know that there is a problem but in this case the keyboard would prevent the machine from powering on because of the "liquid Damage". Now if i plug the keyboard in while the machine is powered on i see the WI-fi light turn on but i don't see the caps lock light blink at all. At this point i have tried reseating the CPU at least 10 or more times and the RAM at least 10 or more times. I have also tried different slots and stick to no avail. At this point i don't know what to do. I want to fix this machine as it is the best laptop out of all my computers. I have already pulled the RAM and HDD for use in other computers until this machine is fixed. What else can i try or look for to try and determine the problem?
