Question about Canon Speedlite 550EX TTL Flash

My flash don´t recicle more

My flash turns on and all functions works well, but don´t recicle. I set it in ON and make a low sound, the pilot lamp don´t take any colour and the low sound stops. Nothing more, but all the other functions works. What´s wrong? I use a lot of new alkaline heavy-duty batteries.

Never use Heavy duty batteries they do not have high output. They are for clocks. and they're cheap. Clean the contacts with a pencil eraser too.

My left turn signal started to only work about 50% of the time, it wont work hardly at all now. the right turn signal is fine. When I try to use the left turn signal, there is no dash indicator lights


Hey Bob how's it going ? I have been looking at Chevy service info for your vehicle and this a little on the complex side or that is the way it sounds from the turn signal description !
Turn Signal Lamps
The smart flasher (GMSF) is an automotive flasher designed to accept turn, hazard, and brake inputs. The GMSF will provide corresponding outputs to the exterior lamps and instrument panel turn signal indicator lamps. This lighting system has dedicated lamps for the turn/hazard functions and dedicated lamps for the brake function. The system incorporates the use of flash rates for diagnostics. The flash rate is a calculation of the number of flashes that occur within a 60 second period. This system uses a percentage of on-time to off-time called duty cycle. For the bulb outage condition, the indicator of the vehicle side on which the outage occurs shall assume bulb outage flash rate mode. The opposite side indicator will assume the normal flash rate mode for an input from the non bulb outage side of the vehicle. Hazard warning lamp outage will maintain a normal flash rate as long as 2 or more exterior signaling lamps are functional. During all modes of operation, the IPC will receive the same flash rates and duty cycles that the exterior lamps receive. The IPC will then control the indicators in the cluster. The vehicle operator will be provided with an audible and visual indication of the flasher operation. Below is a table with flash rates and duty cycles:
Are all your bulbs good ?
Operating Condition
Flash Rate
Duty Cycle
Normal
75 to 105 flashes per minute
45% to 55%
Turn Signal Lamp Outage
2 or 3 times faster than normal flash rate
35% to 55%

03 chevy venture rt.front parking light&turn light don't work replace bulb&socket


The rapid flashing occurs because of the light problem. If the 20A PARK LP fuse in the underhood fuse block is OK, the front marker lamps and the park lights should turn on when you set the headlamp switch to PARK. If the 10A T/SIG fuse in the instrument panel fuse block is OK, and the ignition switch is on, moving the turn signal multi-function switch to signal a right or left turn should cause the turn signals to flash. If this doesn't happen, check for a missing ground connection to the socket you replaced and check to be sure the replacement lamp was not forced into the socket backwards (it happens).

Samsung p6163wx - lamp sign flashing with a loud noise fan on, no picture. Replaced with a new bulb - did not solve the problem


This set may use a color wheel if it has a lamp. A bad color wheel will make a fan like or high pitched sound.

If the wheel actually shatters (it can) the set will not function and will turn the lamp off.

See photo of color wheel and if you need to know I can tell you how to look at it.

Samsung HLP 4663w dlp-hdtv replaced lamp and ballast, still not working. lamp/standbytemp and timer all flashing. i get no clicking on ballast, upon power up all i hear is low fan or vibration sound which...


If the capacitor on the ballast was puffed up or blown up you have to replace the lamp, ballast & SMPS at the same time. But if the ballast is not trying to fire the lamp it sounds like the color wheel is not coming up to speed. If this is the case, the set will not turn on.

580EX speedlite not firing


Does the pilot lamp light up? If so can you fire it manually by pressing on it? If the batteries are low it may simply just be taking a while to charge, the camera will not wait for it to be ready to fire and it may seem to be not working. If your flash can be fired manually however, there may be a problem with the cameras shutter or the hotshoe. You can do a basic check by pressing the star button at the rear of the camera, you should get a pre-flash. If not, there is a problem with the cameras hotshoe which you will need addressed by a service centre. If you get a preflash you can next check the cameras shutter by setting the second curtain to sync with the flash. This can be done via the cameras "Custom Function" menu, c-Fn 15. Set the camera to TV mode and chose a 1 second exposure. Take a shot with the flash attached, if the shutter is working correctly, the flash should fire a pre-flash and then a main flash. If it doesnt, the switch inside the shutter is broken and the shutter needs to be replaced. This is a pretty labour intensive repair and you may consider an upgrade as more economical.

Daytime Running Lamps
The daytime running lamp (DRL) system is designed to turn the high beam headlamps on, with a reduced light output, and without illuminating the high beam indicator lamp in the instrument panel. You have a DRL Module.
The multifunction switch is the stalk on your column.

This is 96 F150 circuit. Don't have 94.
