Jayon, Need more information!!! Did unit work "perfectly" day before? What did you SEE on the screen when you pushed the on/off buton? How many hours of use does this unit have on it? Is there a blinking LED power indicator on the front panel? Does unit hav sound or no sound? Does screen go completely BLACK? This symptom you have described leads me to think that the unit's SMPS/inverter power supply is going into "SHUTDOWN" mode to save itself from self destruction!!! You will need a Tech to look at it and try to effect a repair. There's not a lot of options you have open to you at this time. If you feel brave enough to try to do a close visual inspection of the switch-mode-power-supply and inverter supply on your own, get back to me. You will also need to do some research on the web for information such as "bad capacitors", "cold-cathode-fluorescent-tube replacement", "switch-mode-power-supply" repair and or "LCD monitor repair and or recapping" You also need to view monitor disassembly video clips on youtube to familarize yourself with what is inside a typical LCD monitor/TV. But that's only if your technically inclined. I'm louis12fix on fixya or lmistyrel @aol.com
Bye for now.

Lg LCD monitor turns off after 5 seconds


Does it stay on when you plug it in IF the serial cable is not connected? Ours would come on and display "connect cable"...then when we did, it would shut off. Turns out it had a bad capacitor on the power board. Cost $1.25 to replace the part.

My tv has power the red light stays on and when it does work it some times shuts off while watching it.


Looks like there's some loose contact on ur main board. Its called cold joints ( solder joints ) Get a tech to have it checked to resolder it or if ure good at it then resolder the parts carefully without touching other components. Update here if these helps.

I think you need to get Sky because it will give you 100% coverage of all terrestrial channels. You may need to retune the television otherwise just get sky
