Here it is. Also The procedure NOTE: The fuel pump relay is located in the engine compartment, attached to the relay bracket mounted on the front of the dash. Other than checking for loose connections the only service on the fuel pump relay is replacement.
Verify that the ignition switch is in the "OFF" position.
Good day sir, Check the connections where the fuse fits into for bad connection due to corrosion. Check to see if the switch is not faulty by measuring the contacts with a meter when opening and closing. Check the wires that connects to the switch, check the pump relay (which may also be faulty) to see if there is a bad connection due to gunge (Corrosion always sets in at electrical connections) or if the wires that connect to the relay base are firmly connected not loose. (Remember rule of thumb law_always check for corrosion and loose connections with any electrical fittings, as a lot of people have replaced new parts on their vehicles in vain only to be left with the same problem and wasting money. I have found this to be a major problem with the electrics in most motor vehicles throughout my years of experience. (Most repair shops will not tell you this as they would rather bill you for replacing a new part than help you without making money out of you) Although there might be some honest one's around, but few and far between.
if this is either of the 51" or 56" DLP tv's, it is very simple.
-Make sure tv is UNPLUGGED!
-Open the side compartment on left side of tv as you are facing it from the front.
-Take off the door and you will see the lamp housing.There are 2 screws facing you.Unscrew these and set the screws aside.
-Now pull on the housing a little and it should slide out.You may need to wiggle it a little.
-Set housing down on table or somewhere with good light.Make sure not to touch bulb of either the old lamp or new as oils from fingers can distort picture.
-Now,undo screws on shiny metal piece.There are 2.Take off metal housing piece.
-You now see the back of the bulb.If you look at the lamp from the front,you will notice where the 2 wires are fitted into a bracket with 2 screws.
-Unscrew those screws to loosen the bracket.The replacement lamp should have the exact same bracket.If not you can just undo the wires to the old lamp and connect the same wire harness to the new one.
-once the wire bracket is unscrewed, pull it out of its fitting and then unscrew the 4 screws holding the lamp in.
-Take notice of how the shiny metal clamp-fitting is situated to hold the lamp in place so you can put it back on the right way.
-Once loosened, the bulb should be able to come out and you can put the new one right in it's place. Make sure to keep the top wire connector on the bulb at about 11 o'clock and that a nub on the bulb fits through a spacer on the shiny metal clamp-fitting.
-Now tighten the 4 screws on the clamp-fitting and make sure the wire screw connectors on bulb are tight as well.
-Take the now loose rubber-covered wires and tighten them into the bracket-fitting the way the old ones were,with plugs and lamp facing the same way.
-With everything now tight,put metal housing back on and tighten the 2 screws down.
-Take the whole unit and slowly slide it back into the tv making sure that the plugs slide into their rightful place.This should be easy,but may require a wiggle or two.
-Now screw in the 2 screws you have left into the plastice mounting piece. Re-attach the door and plug the tv in.Wait a few minutes and then turn on tv.
-It should work.If not, unplug tv and check all connections.
TIP:Do not put a cold bulb in and then turn on immediately.I like to let the bulb sit in the tv with it plugged in for a while until the bulb is warmed and ready.
Good Luck! -Chris
The large block is a factory amplifier - in your car (as was in mine) you had a partially-amplified system. The front speakers were driven at speaker level from the head unit, but the rears were fed a line-level signal from the head unit to the amp, which then boosted to speaker level. The harness then sent the speaker level signal to each rear speaker.
What you can do is fit your new head unit. The fronts will interface perfectly with no issues. For the rear, run new wires from the adapter harness at the back of your head unit, back to the new rear speakers, and connect them directly. Then everything will work as it should.
