I managed to solder the new chip to place (can't believe I pulled it off), now the DTV is working again!
The soldering method was a bit unorthodox, but it went fast and clean - multimeter checking for shorts took a lot more time as I wanted to be sure I'll not short the new chip.
HUGE THANKS TO JSAILY for the replacement chip - what a fellow! He sent it to me not wanting anything for the chip or the trouble of mailing. It's heartwarming to know that some people are willing to help others for nothing else than the joy of helping!
