Re: Vizio VX42L - functions fine, but bad colors

Sorry it took me so long to get back. Holidays, shipping, business trip, life in general :o)

So I tried to replace the as15 chip. I should have practiced a bit more. I bought several. I got the first one on, but no picture. I wasn't the happiest with the soldering job. I have to give you guys that do this a major kudos! I had problems even getting the chip off. I eventually had to flow a bunch of solder on and heat in a circular motion to remove the chip. Got the new one on, but not the easiest to just hit the pins. Some...

Have my nieces 42" Vizio. She's had it for several years (2007 mfg I believe). Color recently started to go bad.
Powers on no issues; sound, no issue; just color issues (across input modes). Remote works fine.


I've done several hours of research. Found the common issue with Vizio's is the U33 and not powering on completely, but that isn't my symptom, and my meter readings indicate the regulator reads ok, based on values I've seen posted here.

Powersupply readings
24V lines both read 23.7v
2nd 24V lines both read 23.7v
12V lines...
