Problem with Samsung LN52A550P3FXZA

[stacysturges]

Hello,
I'm experiencing an issue with my Samsung LN52A550P3FXZA. Upon powering it up, I initially see a ghosting effect in the background along with some slight red pixelation in certain areas. This then shifts to green pixelation in the black areas. The picture quality fluctuates with noise for about the first thirty minutes before it eventually clears up. I suspect the T-con board might be the culprit, but I'm also concerned that there could be a problem related to my previous repair. When I turn it on, I hear a click, and the red LED light flashes three times before the screen comes on.

Any advice is appreciated!

Same old, very old problem, you have to change the chip called as15 or as19 on the tcon boards, or even try to resolder it with total old tin removing (this is my personal suspect, never tried), needs skills of smd soldering, tons of yt videos about that chip.. bye
