Disassemble a rear-projection television to remove valuable components. Rear-projection televisions offer the combination of the television and a cabinet and audio system. Many of the components are made with precious metals that are salvageable after the television starts working correctly. To disassemble the television correctly without damaging the parts, all that is needed are standard tools. There is no need for a technician or repairman to complete the disassembly.
