Http://www.qsc.com/support/library/schems/Current/RMX%20Series/rmx1850.pdf is a similar product, ie perfectly identical in most respects. This may not be trivial. Good luck.

What if the speed LEDs on the VR2/VSI begin to flash?

  • Determine if the battery charger is connected to the power base. When the battery charger is connected to the power base, a charger inhibit feature keeps the power chair from driving. This is indicated by the VR2/VSI speed
    LED(s) flashing.
  • Determine if the charger harness fuse has blown. A blown charger fuse can cause the charger inhibit to
    activate.
  • Determine if all controller connections are plugged into the power base properly. If the 3-pin charger
    inhibit connector is not plugged in properly, then the charger inhibit feature will activate.

Accidently changed something and not able to get antenna tv now - do not ahve cable here at work


I am unable to see at a glance how to correct this but it is between its menu, channel and volume buttons to alter the settings it may be worth to run through the re-tune sequence below?


To preset a channel or to change a preset channel, follow the procedure below.
1) Press the POWER button to turn on the TV.
2) Press the MENU button so that the menu display appears
on the TV screen.

Then, press the VOL(ume) ? button.
4) Press the CH(annel) ? or ? button to point to "AUTO PRESET CH".
Then, press the VOL(ume) ? button.
The tuner scans and memorizes all active channels in your area.
? The TV distinguishes between standard TV channels and cable channels.
? When AUTO PRESET CH action is completed, the lowest memorized channel reappears on the
screen.
? When you press the CH(annel) ? or ? button after selecting "AUTO PRESET CH", the tuner
will stop at the memorized channels only.
? The TV may recognize TV channels to be CATV channels by the receiving conditions. In this
case, try AUTO PRESET CH action again in the fine receiving conditions.
? When AUTO PRESET CH is activated where there is no TV signal input,"NO TV SIGNALS"
will appear on the display after the completion of channel scanning.
[ADD/DELETE FUNCTION]
1) Press the MENU button so that the menu display appears on the TV screen.
2) Press the CH(annel) ? or ? button to point to "CHANNEL SET".
Then, press the VOL(ume) ? button.
3) Press the VOL(ume) ? button so that "ADD/DELETE" is selected.
4) Use the CH(annel) ? or ? button to select the
channel you wish to put into memory or to erase from memory.
Note: The menu will disappear in about 10 seconds.
Perform "ADD/DELETE" function while this display appears on the
screen.
? Press the VOL(ume) ? or ? button to light up the channel number
in LIGHT BLUE if you wish to add the channel into memory.
? Press the VOL(ume) ? or ? button to light up the channel number

5) Press the MENU button to exit the menu.

Hope this helps.

2004 harley flstc ignition goes on even when ignition is switched to accessories


Sounds right to me. Follow the wire from the ignition switch. ie. the acc wire (one wire) should be getting power. That wire powers the radio circuit. i suspect it it feeding the or an ignition power circuit now.

TV cannot turn on


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Action-3: Replace the main board!!!

I have a sharp aquos lc-c4677un its not turning on at all now. When I push the power botton on the tv, the power light turns on and about 2-3sec the power and opc light start to blink and thats about it.


How are the power and opc lights blinking? Do they blink simultaneously or does one blink then the other? How many time do they blink per second? Also have you had it fixed yet? and if so what was done? I had a similar problem with my set.

I need the code for a Vizio LCD HDTV


There is no code for vizio tv's for that remote so you will have to do a PowerScan through all the codes to see which one will work. The procedure to do this is below.

Step 1: Manually turn off the device you wish to program (TV, VCR, DVD)

Step 2: Press and hold the appropriate device key (TV, VCR, DVD) until the red LED illuminates. This indicates that the remote is in programming mode.

Step 3: Press and release the power button. The LED flashes once and stays ON. Indicating that the remote is in PowerScan mode.

Step 4: Press either CH+ or CH- button repeatedly until the device switches on. The CH+ button searches upward in the code list while the CH- button searches downward.

Step 5: When the device turns on, press and release the OK button to store the new code and exit.
NOTE: If you press the CH+ or CH- again after the device turns on, the device will not be programmed and you will need to repeat steps 1 - 5.

Step 6: Press any other operable button (VOL+ or VOL-). If the device responds, no further programming is required. If the device does not respond then repeat steps 1 - 5.

Step 4: Press either CH+ or CH- button repeatedly until the device switches on. The CH+ button searches upward in the code list while the CH- button searches downward.

Step 5: When the device turns on, press and release the OK button to store the new code and exit.
NOTE: If you press the CH+ or CH- again after the device turns on, the device will not be programmed and you will need to repeat steps 1 - 5.

Step 6: Press any other operable button (VOL+ or VOL-). If the device responds, no further programming is required. If the device does not respond then repeat steps 1 - 5.
