Need an adapter from shielded RJ12 cable to DB9-M

The shielded RJ12 cable has connectors (plugs) with metal covers connected to the cable shield.
We would like to have these shells connected to the shell of the DB9.
There are adapters for RJ45 with that capability.

I need a converter that will allow me to hook up the rj12 cables to the coaxial connections on a 16 channel revo dvr

you wan to hook up coaxial to rj12 ,if you you do that the wire of rj12 has not to exceed 3 meters
cause camera signal (video) to become weak. Camera Video signal has to be fed only to coaxial cable, coaxial cable has an insulation to prevent interference.
so if you want to hook up be sure put a shielded wire.
thanks......hope this help.

This kind of symptoms is an indication of faulty T-con board. This board has a connector to the main board and to the panel. These connectors must be pull-out, inspect, and then re-insert and ensure that they are properly seat-in to isolate loose connection from fault. If the symptoms still persist, you have to replace this board to resolve the problem.

Opening the back cover will void the warranty. If your unit is still under warranty period, avail it because the manufacturer will fix it fro free.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

MWhere is the noise elimantor for the radio sometimes when I am driving and hit a bump the sound of the engine comes into the radio speakers I have to shut the radio off it is so loud

Hello! Engine noise is removed via shielded cable...The shields are then grounded to the chassis...They are loose or corroded at the contact point...Rather than hunt for its location...You can ground it to the floor pan...If your vehicle is equipped with the Premium sound system...Pins #3 and #7 on the 8 pin radio connector are the shields...Splice two runs of 10 gauge Green wire to each of these pins and connect both ends to a ring connector...Solder connections...Bolt ring connector to the floor pan...Insure contact point is bare metal...

Need directions on how to change the starter on a 1994 cadillac deville

On a 4.9 v8 this is relatively simple

Step 1.... Before you get under the car, Disconnect the battery and look for the metal shield. The best way to find it is to follow the red (power) cable from the battery. It goes straight to the starer. You want to take out the metal shield, but you will only be able to take out the only accessable nut from the sheild from the top. The other will be from below (later). Take out the 1st connector/nut holding the shield. This should be located by the will see the metal shield is protecting the wiring from burning on the exhaust manifold.

Step 2...Then raise the car on the lift, take off the long / wide plastic shield under the radiator (allowing manuverability and you to see what you are doing). Then remove second plastic shield covering the starter.

Step 3...This will allow you to take out the 2nd bolt holding the metal shield (from step 1) protecting the wiring harness.

Step 4...Then you will be able to unfasten the wiring and bolts to remove the starter.

Step 5...Replace with the new starter, reconnect everything and bolt it ,etc. Dont forget to put all the sheilds back in place and make sure the wiring harnesses dont touch the exhaust manifold.

Step 6...Lastly, lower the vehicle, raise the hood and dont forget the nut on the metal shield !

Step 7...Reconnect the Battery

I want to replace ignition lock cylinder on my 1998 Toyota 4Runner do I need special tools to do it? or what are the steps to do it? thanks.

You have to remove the plastic cover underneath of the steering wheel, after that the metal shield behind the plastic cover. When you remove the shield you will get access to the ignition lock cylinder. Disconnect the wire harness, remove the cylinder, install a new cylinder. Connect the wire harness, install the shield, install the plastic cover.

PS: Before start write down the code for your stereo (if you have one), disconnect the negative cable from the battery. Be careful when you work around the air bags.

How to install a color wheel on a samsung hl-p6163w

To install a color wheel on HL-P6163w just: unplug set and remove rear cover. Remove the screws holding the plastic cover over the audio/video jacks. Remove the screws holding the large metal box (digital module) in place. Disconnect the plugs on right side of the digital module and disconnect the plugs remaining in your way of removing light engine, located on the metal sheet on right side of set. Remove the two screws that hold the light engine in place and slide towards you carefully so as to not stretch any remaining wires. Black, plastic cover that shields the color wheel has three screws that hold it in place, and you need a long screwdriver to reach them(matgnetic tip if possible). Once you remove the cover you will see the color wheel and the screws holding it in place. There are two plug connectors attaching it to the shielded DMD module and make sure to put the ribbon connector back on the right way. It has contacts on one side only. Carefully reconnect all plugs and if the plugs are identical you need not worry in which order you connect them. Make sure that you plug all connectors in and engage safety switch for lamp cover to test your work. It should be fairly easy but a bit time consuming for your first round with light engine servicing. Keep your distance from the ballast that runs the lamp while testing as it can pack a powerful punch. Good luck, Russmann.

Broken sayno part

Hi wingshooter,

Your son is right. the 2 screw of the male should be fasten
to the hole of the female dvi. replacing the whole part
need careful de-soldering.

However, if the shield is still there and only the hole where
to screw in the male end of the cable, you can get from
old computer discarded around. you only have to remove
the two hex screw and replace it into your DVI female.
Observe that the head of these screws are hex, six corners,
and the hole is threaded. that threaded hole is where to screw in
the screw attached to your male DVI socke

Good luck,
