In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

This is the TV tuner and the manufacturer is XuGuang Tech Co. Ltd

Check the remote control for its infrared emission. Check it with fresh batteries. Check it by pressing all the keys. You can detect the presence of infra-red emission from the remote control, using a cell-phone camera. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. In some cases, the remote control might need to clean.

hi first of all u should check ur transistor connections.Check your Horizontal and vertical output transistors.You should also check the horizontal and vertical yoke connections as well as your low voltage regulators.... if any of these got damaged u should purchase a new one.. but try to purchase with the help of a tv service assistant...
thank u!!!
rate me

No. The newer LCDs can do both. But they are a TV to start with the option to hook up a Desktop.

Public sales or auctions from corporations or schools are the best places to get computer cables for very very cheap.

If you are looking to purchase new cables places like

ive had this tv/monitor for years just sitting there collecting dust. a buddy gave it to me to see if i could fix it because he couldn't. well gotta open it up and look on one of the main boards and look for blown capacitors. look for the ones with round tops. they should flat not rounded/bulging. replace those and then your monitor/tv should work again.
