I had ps3 hooked up to 720p tv then hooked it up to 1080p moniter now it won't show a picture on 720p tv


you have to switch it back to 720p mode before disconnecting it from the 1080p television. If you're using HDMI, and then switching back to the a/v connectors, then you have to switch the output settings of the ps3 from hdmi to a/v as well.

My insignia lcd37 is hooking the comcast modem and works at times. Other times the sound is on, but the picture is blank. Is it worth fixing or just start over.


Okay you TV is hooked to a comcast modem? or do you mean My tv is hooked to the comcast converter box? A no picture but sound you want to first check you cables also try hooking up a dvd to the tv and see if that picture comes on if not and you got no pic and sound this would mean the backlight on this tv is dead or you got a bad inverter not converter, inverter inside the tv. Meaning it needs the repairshop but try and hook up a dvd to it and see if you got picture if so you cable box might be the issue call comcast!

Thanks and please leave valuable feeback and ratings today!

I can turn computer on but screen is black


Try to hook the laptop up to an external monitor, that will point us in a general direction to help you see if it is a video output problem or a motherboard failure. If you can see a picture on an external moniter/tv, then you may have just lost the screen. If it doesn't produce a picture on either one, then you may have lost the video card and/or output on the motherboard.

No tv picture - only audio - after pc to tv box hook-up


Hi I am a silver surfer but this is how I got it working
First off get the program tou want to watch up on PC Moniter(screen) Then connect 3 cables
Yellow cables / One end to tv other end to yellow hole rear of PC/TV Box

Grey cable small end goes in PC/TV Box just behind the wirds "kworld" other end goes into back of your Computer ,you need to check your Computer manual to see the which one is the connection to your Computer screen(moniter),mine was blue with 2 screws , disconnect this and screw in Grey cable

Black cable narrow flat end into front bottom of Computer ,other end intoPC/TV Box end hole next to yellow cable

Switch on TV and change AV until you see your program, sound will be thu your Computer Speakers NOT your TV

THIS IS FOR A DESKTOP COMPUTER

Not to computer saavy so please keep it simple. I have a Sony Vaio VGC RA840G desktop with 5.1 surround sound. Also have a Samsung LN46A850 S1F HDTV. Also a home theater system. This is hooked up to cable...


From the looks of the TV manual you have everything right, so it's very odd you're running into this problem.

Have you tried swapping through the sources? I find with one of the TVs we have on display at work that any time I'm having some troubles with it I will change the source from PC to something else, then back to PC.

If that doesn't work then I'd suggest you try reseting the sound settings back to factory default. The instructions are on page 45 of the TV manual. From the TV menu select "Sound", then "Sound Reset", then either "Reset All" or "Reset Sound Mode". I would suggest reseting all.

Last option would be to try using the headphone jack in the side of the TV, though this is a last resort kind of thing since you would have to unplug it every time you wanted to use the cable box.

Hope this helps :)

No picture or sound on ordinary TV after hooking up with HD TV


You system is still out-putting through the HDMI cable. Press & hold the "on" button after the system is already on, it should go back to regular factory settings & show up on your screen.

Toshiba CF36G40 36" TV (picture snowy)


you have a bad tuner you can replace it or use vcr if you still have one around. hook it up with av cable like your ps2 and hook your cable to it and use it to change channels. If you want to replace the tuner it will require soldering and you will have to order it somewhere. i would try partsore.com. The tuner is the metal can the cable goes into inside the tv.
