The regulator killed the vertical white bar on comp on my LCD tv but there was still a dark bar where it was. The cap did nothing but it's a 220uf not 470uf so I'll need to test that.
Doing the pin 155 thing was not fun but I figured out an easy way.
I bent a thin spring straight and slid it behind the pins on the cpun till it was behind pin 155. I put some tension on the spring, got my soldering iron hot and dry and applied it to the pin. Ting! Came straight off the pad. Then I straightened the pin by placing a blade across the top of all the pins on that side to support it and stop it from bending at the chip.
That's the easy part.
Soldering a resistor to that pad is not. It's a weak trace.
I lifted It, soldered it to 154 then 156, finally got it free and decided to glue the resistor to the cpun and bend the legs to have 0 tension against the pin or trace then soldered in place. It's strong and got the job done.
I wired up RGB from the internal amp with 75 ohm resistors in series and skipped the 1.2k terminations.
Fired up the mini and was instantly impressed by nice bright writing with no ghosting.
