Question about Sony Ericsson W550i Cellular Phone

Rear Camera Light LED

To whom it may concern, I'm looking for a component number for the real camera light LED. I am also looking for the manufacturer of that LED as it is not freely available in South Africa. I would like to know this not for repair but rather for a project I'm busy with and I need LED's with exceptional brightness. The W550i has one of the brightest LEDs I have seen but its difficult to find out whose manufacturing them. Can anyone please help me in this regard. Kind regrds.

a hand full of fuses as you
use a LED test light or voltmeter to find the right wire

and use those color wires as your power /earth for the reverse camera

or you need the rear loom wiring diagram for that 2006 chev

How to see if your remote control is actually working


For remotes which use an IR connection you can see if they are transmitting using this trick. An IR type of remote will have one or two LED's on the front end. If it doesn't, than it may be an RF type of remote - this tip will not work for those.

Get some electronic device which can view a live image on a screen. A cell phone camera, digital camera, digital video camera, and (I think) even a web-cam will work. If you're using a digital (still) camera, you don't need to take a picture as long as you see a live image on the screen of whatever the camera is pointing at. Take your remote and find the LED on the front end. There may be one or two. (If there's two, one actually isn't an LED, but that's not too important.) Point the front of the remote at the camera (LED's facing the camera), and press buttons. You should see the LED's light up in the live image. While these LED's normally produce light which the human eye can't see, digital image sensors can, and they change this invisible light to light we can see on the screen. (Cool right?) So, if your remote is working then you'll see the LED light up on the display. (To make sure your camera is actually working as I am suggesting here, find a remote which you know does work and try it.)

The LED should light up for every button pressed. If one button doesn't make the LED glow, you may have a bad button - try pressing it firmly. Buttons can wear out. The image of the LED may appear steady or it may pulse or blink on the viewscreen - this is normal.

If the LED doesn't light up, and you know your camera works like this (you've checked a good remote), try new batteries - that solves most problems. Check the battery contacts in the remote - if they're corroded, (white flaky stuff caked on, looks like dried up salt) - you can clean the contacts with a solution of water and baking soda and a Q-Tip. Use a knife to remove any large chunks. Also, some fine sand paper works too. Both the flat contacts and the springs need to be cleaned. Wash any tools (and hands) with soap and water afterwards. Handle corroded batteries as little as possible - or better yet, use gloves.

If you have good batteries and the contacts are clean, and the LED is not lighting up - it's pooched. Try getting a replacement from the manufacturer (call or email/write them), or use a universal remote.

If you've found this tip helpful, please check the box below. =8o)

What phone should I buy if I'm looking for the best camera?


What do you mean by "best"?
Best resolution? Best low-light ability? Best color rendition?

This is like asking "What's the best flavor of ice cream?"

My Maestro IR remote no longer works after 10 years


The infrared (IR) LED / remote may have stopped working. Since it emits IR light when used, you won't be able to actually see the light with the ***** eye. This makes it difficult, but not impossible to determine if the LED / remote is working or not. You can see if it works by pointing it a night time security camera - the type that has it's own built in IR LEDs to light up the area and does not need visible light to shine on the area (some video cameras can also "see" this light when playing back video taken of an active IR light source). Either record or have someone watch the display while pressing a button on the remote and aiming at the camera. You should be able to do this in broad daylight it will look like a flashlight shining into the camera.

If the LED in the remote is proved to be functioning, the IR receiver in the switch, or some other internal part of the switch may have failed. Since the receiver doesn't light up - there's no way to determine if this is the case without actually replacing the switch. It doesn't matter really, as there are no user replaceable parts in the switch - it either works, or it doesn't.

Ultimately, the best way to troubleshoot will be by replacing components with known good types. Use a battery that tests "good" on a tester, in a new or known to be good remote, used on a new or known to be good switch. You'd would deal with the situation by swapping only ONE component at a time. Once you change the device that allows to circuit to work, replace the new components with the old - except to last one; as this was likely the component that caused the failure.

Try taking the remote to a Home Depot, Lowe's or other similar store with a display of these switches. Do what you need to do to your remote to see if you can control any of the switches/ lights.

Good luck!

I cant turn tv on with remote


Maybe the problem is in the remote. To check the remote use a cellphone camera or maybe a digital camera will do. Just focus the camera on the remote LED it is located on the top of your remote, while pressing the buttons of your remote put the camera on the LED if the remote is good you will see a blinking lights on the camera while pressing the buttons of the remote. If the light doesn't show try to replace the LED on your remote or maybe just clean it also clean the button panel with a pencil eraser, Usually the remote control is the problem, Hope this may help you if the problem still exist just email me...

I need a code for a rca and a coby remote controle


Sanyo. 1004, 1048, 1049, 1073, 1080, 1162, 1169, 1180

1. Manually turn on the component you want the remote to control
(TV, VCR, DVD, satellite receiver or cable box).
2. Press and hold the component key (TV, VCR·DVD, SAT·CBL) you
wish to program. The LED indicator light turns on and remains on. If you release the component key any time during the Direct Code Entry
procedure, the LED indicator light blinks four times, and the process
is exited.
3. While holding down the component key, enter the four-digit code that corresponds to your component’s brand. While you are pressing the numbers, the LED indicator light turns off.
5. After the fourth number is entered, the LED indicator light turns on. At this time, release the component key.If the LED indicator light turns off, you have entered a valid code and have followed the correct procedure for Direct Code Entry. If you enter a code number that
is not in the Code Lists or you do not follow all of the steps for Direct Code Entry, the LED indicator light blinks four times when the component key is released. This is an indication that a programming error has occurred. In that case, repeat the Direct Code Entry process from step 2 and try the next code listed.
