The IC chips generally do not fail, but they could be damaged from leaking electrolyte from the caps - if they are not corroded, then they should be OK. Green corrosion on the capacitor leads is 1 sign that the caps are defective. A complete recap should bring the TV back to life, if all the circuit board traces are not compromised - if they are, then they need to be repaired. An ESR meter would be very helpful if you do not intend to replace any capacitor that does not look physically damaged - they most likely will be electrically damaged.
