- Q: i just set up my new TV but i have to use the remote that came with new TV to control volume and on and off botton how to i combine it to time warner cable remote so that i dont have to use two remotes everytime
- you should be able to program the tv function of the cable remote w/ the codes which control the volume, etc. you must read the manual which came w/ the remote on mine, it's press the program buttonthen the tv button, then the 3 digit code, then the off button, or something like that
- Q: I need to now how to know hook my 360 to xbox live through the ethernet cable step by step in every scenario
- well first connect pc via xbox 360 with ethernet cable then go to (pc) control panel then click on network connections then right click on local area connection then at the top click on advanced then tick (allow other network users to connect through this computers internet connection) and the one below to then click settings and then tick every1 one (xbox 360) on the xbox 360 main menu go left till system and click on network settings and then click test xbox live connection and hopefully all of it will say comfirmed or connect then join xbox live at the xbox live marketplace thankyou hope i helped!!

- When there are levels of letters appear in the ZR will often be omitted in the Z, such as ZRA abbreviation for the ZA, ZRB abbreviated as ZB and so on So ZC and ZRB difference is that ZRB's high flame resistance ZC a grade, but can meet the national industry standards
- Q: i changed fuel filter, idel control sensor,spark plugs,checked vacume hoses, cables, HELP!!
- The trick for using a instruction manual transmission is getting a sense for the factor the place the take carry of surely connects the engine to the transmission. Take the vehicle to a point vehicle parking zone the place there are not the different automobiles interior of reach. Your objective is to force the vehicle purely some ft at a time. supply it merely purely a sprint of gas and permit the take carry of out slowly. as quickly because of the fact the vehicle starts off to go, push the take carry of in and be conscious the brake. Repeat till it feels organic. Then stumble on a place to coach with a reasonable incline. You objective is to as quickly as back pull forward some ft at a time without rolling back each and every time you're taking your foot off the brake. it particularly is surely much less stressful than it sounds because of the fact the vehicle will take purely a sprint of time to start up rolling. as quickly as you grasp the technique of using stick, you are able to discover which you surely like it because of the fact it grants extra administration. good success Don
- Q: I have a 1992 Nissan 300ZX it is not a TT or 2+2.if you are looking at the engine, on top are two adjustment cables. I know the far right is the accelerator cable but is the one on the left the idle adjustment cable? also is it best to have the accelerator cable as tight as it can go without have it pull on the switch or just a little loose?
- On most cars, that 2nd cable is for the cruise control if it has a 2nd cable right next to the throttle cable. As for your other Q, most of the time the throttle cable has a tiny bit of slack in it (it's not loose by any means, but it's not normally as tight as a banjo-string unless the gas pedal is depressed from inside the car). There's probably no need to tighten it unless there's an abnormally large amount of slack (like if nothing happens when you initially press the gas pedal in the carotherwise it's probably just fine as it is.).
- Q: i pulled the cable tv hook up out of my tv can you help me please.
- My understanding of what happened is that the Cable In jack on the tv broke. I'm trying to think of the cheapest way for you to solve this without special equiptment. This way is a bit annoying but it would work. If you have vcr many can recieve a cable signal. What you would do is run the cable cable to the Cable in on the vcr then run a composite cable (yellow, red, white) from the vcr to the tv. This way requires the tv to be on an av station or channel 3/4 (depending on the tv),the vcr must be on and the vcr remote would control the stations. Plus to this way is no need to increase cable services or rental fees just because the jack busted. Otherwise I would recommend considering a cable box or finding a way to fix/replace the tv. Depending on your cable company boxes can either be rented or bought. They are connected to the wall jack with a screw in cable cable. Then you have the option to use and hdmi, composite, or component cable (green, blue, red, red, white) to go between the box and the tv. Honestly a cable box is the best cable to hdmi hook up out there.
- Q: dont I have to do something in control panel to get xbox live?I thought I had to unlock something in control panel
- No, are you trying to do it wirelessly or from an ethernet cable?
- Q: Control cable djypvp22-4 * 2 * 1.5 What does it mean?
- With pvc tube on the line, lighting shop, or electrical materials shop to sell. In order to facilitate identification, with different colors of the wire on it
- Q: What are the national executive standards for cross-linked polyethylene insulated PVC sheathed cables?
- Swallow between the feet of the wire resistance is very small, and the swallow itself resistance is great, the equivalent of two feet between the wires short circuit, so the body through the swallow's current is minimal, will not hurt the swallows
- Q: Does any body know if there is a universal remote control that has the ability to turn a television on at a preset time? My Samsung in my bedroom of course is one of the few that doesn't have a built-in feature to turn itself on at a certain time.I figure that hey, there are (or were, at least) universal controllers that could be set to record programs on a VCR from a certain time, and to stop at another time, so why can't a remote turn on a TV?
- that function has to built into the tv for it to work on a universal remote. Did you check the sleep function?sometimes its there or a function called timer.
