If your TV starts to falter, it is worrying. If your Goodmans LCD TVs starts to develop problems it is a must to get it repaired as soon as you can. The first thing you need to do is to identify the original source of the problem. There are a number of things that you can do to troubleshoot your Goodmans LCD TV.
Adjust all the connections on your Goodmans LCD TV so that they properly fit into your TV.
Dust the whole of the Goodmans TV with the rag. Cleaning the whole of the TV can stop further problems from happening. Use concentrated air to blow any dust from the inside of the TV.
Check the house fuse box to ensure the switch for your Goodmans TV is on. Flip the switch on if it isn't. The switch is part of your "front room" so flipping that switch on and off should also switch the TV on and off. If the TV is in a different room then flip the switch that is relevant to the room the TV is in.
Place the TV antenna on higher ground if you find you are having issues with your TV signal.
Take out the AC power cable from the plug socket. Clean off any dirt and dust on the cable with the rag. Plug the power cable back in.
Replace all the batteries in the Goodmans remote control to stop any issues with the remote control.
Check the TV manufacturer's website to locate a FAQ page which will help solve the issue you are having (see Resources).
Make sure to turn the power off on your TV before attempting to adjust your fuse box.
