Imoudu,
Good attempt for fixing.....always use good quality solder flux & refresh the old solder first before removing the IC.

Mr Parasuraman.S,Albert.V,Eric.R,William.S,Waleed.R,Mark.
Thank you all for your comments sirs. I was told by a friend there are fake ones of AS15 series of this ic.When I used glue,I did check it up with the use of analog metre for continuity.I am doing this kind of repair for the first time,as Eric suggested I will have to practice with junk boards:"practice makes perfect" it's said.Thanks Mark,your suggestion is noted.

Great job Imoudu!
It does take practice to solder those tiny little ICs. I is easy to remove any bridging of solder, simply by dragging the iron along the pins. Using solder is the best way to ensure you have a permanent contact.
Well done!

this IC is called the gamma IC which have to do with colors and the display on that panel. I have a done a repair like that before and worked just fine. my only issue to find good IC's on line. last time I bought about 50 of them and I had a about 20 of them defective sad to say. thanks for sharing and have a blessed day

Thank you.

A very very thin pointed tip for your soldering iron with some magnification to look thru will help. Practice on junk boards before doing final work. You’ll be a pro at it in no time!

Blessings my friend,

Eric

Good job Imoudu! But I at least easily would have soldered those 2 wires onto the replacement smd pins of the AS15-HG chip with solder. I wonder how those still make contact now with only 4 minute glue if you didn't use some sort of silver glue.

I have a similar problem with a Sony TV. Unfortunately, we do not get original ICs in the market. I replaced the IC once, but it did not solve the problem. So removed it and I am yet to try with another.

It is a strange coincidence that same IC number is the culprit always! Many thanks for sharing! It was very useful!
