Whats wrong with my amp?

[dan1981]

Have a problem with my av amp every so often.....

I have a tv running through it and also an xbox plus the speakers of course.

I also have a humax box wired to the tv via a scart.

Now sometimes the missus will watch the tv without using the amp so just use the humax and the tv with the built in tv speakers.

Now the problem - sometimes i'll turn the amp on to try and play xbox or watch a dvd on the xbox and when i flick to the HDMI channel i get nothign on the screen.

I think the message the tv shows is "no signal" which is different to if the xbox is turned off and i flick the hdmi channel on (i get "check cable")

If i turn the tv off or the xbox off or the amp off it still does work, but if i unplug the lot at the mains and then turn back on it works fine.

So where is the problem?

Cheers

The problem is almost certainly that you bought "The amp with no name". As a result, the amp has taken umbrage to your lack of respect for his horse, and shot 3 of your henchmen. I suggest hiring a specialist with an unusual shaped nose and a long gun to solve your problems, although I can't guarantee that this will go smoothly for every film.

yes what he just said. deffo

and...its more than likely if you have lost the HDMI feed that the handshake between the TV, the amplifier and the source has been lost. by repowering the amp up you are instigating the handshake again and it hooks back up. pulling the cable out and putting it back again can also do this.
could well be that one of the items involved in the device-cable-amp-cable-tv isnt 1.3b compliant.

or could be none of the above and the drugs made me say it.

for any issues with HDMI contact the devil as he invented it. he laughed for years with the scart and then when done taking the Pi$$ he invents this.
anyone with early stuff it will always go bump in the night. apart from getting the lot on the same platform you cant do anything about it. we do have switchers out now that are intelligent and hold the handhsake with the device then route content. new series AV amps will start to come out with this and it will then get rid of the huuuuuuge time lags some kit suffers from in trying to hook up the audio and video. nightmare stuff worst we have seen was a certain bluray player at 13 seconds !!
