Your problem sounds like a power supply issue. It is very common that manufacturers use low temperature rated capacitors on the power supply, and over time, the capacitors get too hot, fail and begin to leak. Your problem sounds like a leaky capacitor on the main power supply. You will need to know how to solder to repair your tv. Please take proper precautions when working on your tv. Capacitors can store charge long after the device is removed from power. Working on live electronics can kill you. Make sure you discharge the components before working on them.
