Sharp, for a price, will sell you a new remote. You can also pickup a universal remote, that will work with this TV and just about any other TV/DVD/Blue-Ray out there. Universals can be had quite cheaply.

Your TV has both analog and digital sound output jacks. You will need to connect to an audio amplifier/speaker system that can use either of these types of audio signals. Consult your TV user manual for more info.

Sometimes the lizards can cause a lot of board wear-off as they being highly conductable and when shorted within the electrical circuit can make the secretions runs into the board therby contaminating and shorting circuits. If you are able to remove and use petrol to wash off the dirt on the board, look for open tracks that have burned or corroded. If you are able to trace and rewire using thin strands of wires , and assuming that no component damage had taken place, you can try this out.If not as suggested you need to find the cost of a new board if a final consensus is taken.
