If you'll notice "Dan theman," he mentions that ic sockets aren't recommended because they can oxidize quicker and cause another failure. I suppose this idea carries some weight, more metal and material equals more potential for problems to happen when/if something rusts, but I would also think that if an ic socket were to oxidize easily then you might have bigger problems than a failed chip. Plumbing leaks, flooding, etc.? At any rate the thing that really stuck out to me was his mention that a third chip is needed in order to prevent the two driver chips from failing again. Unfortunately, nobody in the comment thread, not even Dan theman mentioned the name of this third part/chip to be replaced.
I've already messaged him asking about this through my youtube account. Anyway, everybody knows since the dawn of time here that replacing the two chips with MCZ3001DB fixes things. Does anybody know anything about this third part/chip as a culprit for the death of the other two? If this were known, it could be a preventive measure for anyone who hasn't had a failure yet.

i successfully fixed my 36" HD Sony KD-36XS955 by replacing the original MCZ3001DB with new ones from Amazon.
Thank you for your detail explanation.

a few of the trace pads on the board around the ic chip pins completely ripped off is there a way that my project can still be salvaged?
Thanks floydage im gonna try it out an see if it works. But before i try it out how will i know if im scraping the right trace point on the board when connecting the ic pin to the wire then scrapped trace?Quote:

Solder a wire from the pin to the nearest solder joint on the trace. Use insulated wire where necessary (ex: long run). Alternatively, you can lightly scrape the green solder resist off the trace and solder the wire from a pin at the scraped point (i.e. if you're worried about a component falling at the nearest solder joint). It doesn't look like there's much IC pin protruding to solder to so pre-tin the end of the wire (this should be done at both wire ends anyway), then insert the wire down in the hole beside the pin and then solder the wire to the pin.
i used a 40 watt soldering iron first but it was barely hot enough to heat the solder joint. The one im using now is a 60 watt works way better. the solder isn't black the lighting in the pic was bad i also did find some pics of the ic locations but its still difficult to tell where the pins on the left side of the photo below go.Quote:

Please tell us what wattage soldering iron did you use? They look like they've been desoldered with a blowtorch.I haven't seen black solder before.
See if you can find pictures of the two IC locations from others who own the same model television. It might give a clearer picture of what is meant to go with what.
