Sounds like you have an incorrect output signal from the Xbox or a fried chipset in the Xbox. Test the Xbox on another TV or monitor, test another video source on that same connection, if both of those fail, replace the Xbox. Hope it helps!

Just bought a 55" Lg Led tv and i hook up hdmi from cable box to tv hdmi 1 and hdmi from my blue ray player to the tv hdmi 2, ok then i turn the input on both now hdmi 2 work but hdmi 1 has no signal why...


try connecting your blue ray player to HDMI 1.
A) If it works there, then you know the port on the TV is OK & the problem is with either your HDMI cable or your cable box.
B)If it still doesn't work then you may have a problem with the port on your MAIN PCB. if it's a new TV your warranty will cover that as long as the input connector is not physically broken.

Yamaha rx-v1600 hdmi output not working


Have you inspected the HDMI socket? I had the same problem and the socket had been damaged by a tight fit cabinet with insuficcient space behind the amplifier. A sideways cable tug on the inserted HDMI cable had snapped a small piece of plastic seperating the two rows of HDMI connectors, and three were splayed out, so no connection when plugged in. Solution was to carefully re-align the connector fingers and glue a tiny piece of insulating material between the two rows. The output now works perfectly. A bit fiddley, but worth the trouble when you look at how much Yamaha would charge to fit a new socket, or even a new board!

I have a Mogen ML-1508TN 15" LCD TV which worked perfectly well until I moved house recently. Having re-installed it in my new home all I get is "No Sync" on the screen everytime I switch on. My helpline...


In the U. S., we would see "No signal" if there is a problem with picking up the TV station. "No sync" may be equivalent; the tuner may be detecting a signal, but it isn't strong enough for the TV to pick up the synchronization pulses needed to decode the picture information.

You can check this by connecting a known-good video game set, DVR or DVD player to the TV and verifying that the TV properly shows that.

Worst case: you're only using HDMI inputs, and the HDMI circuit was blown out by static electricity during the take-down or reconnection processes. That's been a problem with some cheap HDMI external switches. Before assuming this, try a different HDMI cable; there are some low-quality types with fragile connections at the end.

Scrolling diagonal lines


The cable box signal on the components video have a too high refresh rate frequency, that is the reason for the lines.
Use RCA cables or an alternative connection.
Other solution is changing the display out settings for cable box (from PAL to NTSC etc.)
