Fiio E5 with loose jacks

[jelicof]

Hey guys, i've been using my Fiio E5 for ages now (ever since i read up on it on ABI and bought one myself, ever since then i've been inseperable for years from it. ), and i'm having some jack issues with it. Shifting the 3.5mm Male plug around causes the audio playback to be issues, but i can't single it out to just a single port, so i'm assuming both the input and output are messing up...

Now, i've opened my E5 before due to curiousity (And also an attempt to fix it) but to not much avail, as its not a normal solder job. Is there anyway you guys can suggest for me to fix up the connectivity between the jack and the board? :x

I know a technique, oven baking, that is used to fix connectivities in graphics cards and some laptop motherboards, but i'm afraid to try such a thing with my Fiio (And i've never tried oven baking electronics before >_>)

Help help?
