Hi

I need help on my xbox 360 slim

I connect my xbox to new samsung 23" led full hd monitor via third party hmdi cable

The problem is the screen always turn blank for a sec whenever someone switch on or off the light in my house

Not a major problem but its really annoying while playing games and maybe will develop into worse problem if this continue

Anyone has encountered the same situation or know whats going on? Please help thanks..

Hmmm... 2 issues, either your HDMI cable is faulty, or your home power wiring has some problems.

Simple rules for power hungry AV systems
- Use proper power extension strips
- Surge protector would be nice
- Might want to use an AVR if you think you have power fluctuation issues.

The latter might be true because we got alot blackout during stormy days..
But this only happen if use via hdmi cable not dvi

Sorry but i cant understand what u saying lol. Power hungry av?

he mean,
Audio Video Receiver

eg: Xbox> AV receiver>tv&home speaker
these AV receiver sometime demand clean power and any fluctuation in current would affect the system,

like marauderz said
perhaps the HDMI cable is faulty or there something wrong in your home wiring.
cus, now days, circuit for lightning and power socket are separated, try using different socket in your home?

Sounds more like power fluctuation.

But like marauderz said, might be those he had listed.

try changing the HDMI cable, if it still doesnt work try using another power socket on the wall as well as changing your extension cable, if all else doesnt work maybe u have to look for a UPS with Voltage stablilizer.
