My 42in ilo edtv internal speakers are blown will hooking up external speakers play every input?

You either have a blown speaker or the amplifier in the radio has gone bad. Sometimes a blown speaker will act as an additional ground thus grounding out the radios internal amp. Check your speaker by hooking them to an external audio source. If you do have a blown speaker once it is removed all working speakers should play. Speakers should be replaced in pairs. If they all work its the radio itself. It will need to be replaced.

try check in audio external input use external speakers if it is working maybe your internal speakers are open!

before attempting that:

Look in set menu to see if speakers are switched ON or OFF.

Check on SET and a Box if used that sound is not turned off or low.

If set has hookup for external speakers is external or internal selected.

Does the set have sound when a DVD etc. is connected via one of the rear sets of audio/video input jacks?

SD TECH

Set indicated here has speakers and may have a slide switch on rear to select internal or external speakers.

Also in menu look to see if speakers are switched off.

check your menu to make sure your speakers are turned on.

No, it doesn't have a digital tuner. If you want to watch digital channels you will have to acquire a digital set-top box and connect it to the tv thru the av inputs.

Yes, if your laptop has a VGA out port (that is the external display port - usually blue with 15 pins).
The NEC display has a VGA input on the right-hand side.
You just need a VGA cable that you plug in both connectors.
Then, read your laptop manual to determine how to activate the external display (usually the FN key with an other key that has a display icon on it).
On the NEC display, make sure it is using the RGB1 input (use the remote to activate this input).
That should do it.

NOTE: Make sure your laptop is using a reasonable screen resolution (that is 640x480 or 800x600).

What is the model of the DVD player and the Television.

You're not trying to use the "Tuner" in the ILO are you? Bypass it and use the A/V cables from the "out" of the converter box. I think mine also has the coax type cable from the "to tv" to the ILO, then from the "to tv" on the ILO to the television. Either way should work. Mine works great, its a zenith and I have successfully recorded to discs in my ILO. Just change the Source back to the DVD source to watch a dvd or select the corresponding A/V connections that are hooked to your convertor box to watch/record television.

i dont think that the ilo has a sound output port:(
