Default Altec Lansing MX5021

HI

I have this speaker system which has no sound on the right side. The sub and left speaker is working fine. I noticed that there are 2 power ICs, one driving the sub and the other driving the 2 full range speakers. I suspect that the IC driving the 2 full range has shorted because the heatsink gets really hot. I want to replace the IC but the numbers on both ICs are partially faded, I can only see the TDA7. Can someone please let me know the part number for both the ICs. Please assist.

Thanks

Carlos

There are several TDA7xxx, how pins do they have? Possibly TDA7265 or 7295?
