Hi Altus

This a common Mainboard failure on the LG JT91 if all the LED's flickers.

The good news is that it can be repaired. Much cheaper than replacement.

This will however have to be done by a Service Provider.

Viewsonic projector Pro 8200 will not start / get out of standby mode


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power led, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy.

My d-link router name no longer appears in my wireless networks list - I can not find it to connect to the internet wirelessly


Hi, this seems to be either an issue with your router's hardware or local computer wireless adapter hardware. In order to determine which one is it do the following:

1. Go and check the LEDs on your wireless router to see if there are any blinking or switched off as stated in the official manual documentation for DLink products (can be found here or here more specific).
LEDS are as follows (left to right - per official user manual/doc):
- Power LED = A solid light indicates a proper connection to the power supply. cdekatrr_0.png
- Internet LED = A solid light indicates a proper connection to the Internet port. This LED blinks during data transmission. cdekatrr_1.png
- WLAN LED = A solid light indicates that the wireless segment is ready. The LED blinks during wireless data transmission. cdekatrr_2.png
- Local Network LEDs = A solid light indicates a connection to an Ethernet-enabled computer on ports 1-4. This LED blinks during data transmission. cdekatrr_3.png


2. Check the laptop's or desktop wireless adapter if it is disabled or enabled and if is disabled enable it by going to your computer's Control Panel (either winxp or vista/win7) and go to network connections (in vista/win7 put the control panel in detailed view to see more options) and then right click on your wireless connection and click enable.



3. In a case that also the wireless adapter is enabled but you still cannot see any access points/wireless networks please go to your current wireless connection and right click go "Diagnose", this feature is mainly available in windows 7 or Vista. For windows XP, go to the command prompt by going to Start->Run->type in the box "cmd" without the quotes->Then type in the following set of commands.
ipconfig /release ---> This will refresh your wireless card IP settings/configuration to 0.
and after that command finishes, type in:
ipconfig /renew --> This will get new settings if the wireless card has problems finding an address from your router.

You can always reset your router (unplug from power supply, wait 2minutes then plug it back in)
or:
Reset the wireless adapter (right click from on the wireless adapter shown in the network connections, disable and then re-enable it) or computer.

Thanks please let me know if you need anything else.

Lens light not glow?


1) Does the projector have power? There should be at least 1 LED lit on the body. Make sure that the on/off switch is on and that the mains feed is working.

2) Turn the projector on. Does the fan run? Are there any error codes indicated? Consult the manual for help interpreting them.

It may be that you require a new lamp, however I would verify the projector is working and that the LEDS indicate this before spending any money on it.

I have a switch Dlink (DES-3026). All the status LEDs are blinking together with orange color. Is there any problem in that?


Blinking LEDs show data activity (Send & Receive) at the connected ports. So, there is no problem as long as the switch is performing well

Good Luck!

I need to replace two blue indicator lights and I need directions


I have replaced several of the indicator lights in the control knobs.

Turns out that Dacor doesn't sell exact replacement lights (actually LED modules).

What I did was to go to a local electronics supply store and purchase Blue replacement LEDs and a current limiting resistor to connect in series. Replacement LEDs can vary in brightness depending on your taste ... I chose a super bright LED which makes the control knobs noticeably brighter. The value of resistor will vary depending on the LED you choose (brighter LEDs need slightly more current and as such the resistor value will be slightly less).

Once you've opened the range from the top (remove knobs, grates and burners) then remove a few screws and the entire unit opens with a hinge in the back.
Look over the LED light modules which shine just below each knob and fashion a replacement LED assembly.

Total material cost per LED unit was ~ $2-3 (LED, resistor, wire and heat-shrink tubing)

  • Front LED – blinks red/blue until both disks are powered on, then turns solid blue.
  • Rear LEDs – blinks red/blue until corresponding disk is powered on, then turns solid blue.
NOTE: If the device is not able to initiate the boot process following disk startup, the front is solid red.

  • Rear LEDs – solid blue
NOTE: If a disk is failing, both the disk’s corresponding rear LED and the front LED will be solid red.
During RAID Synchronization
  • Front LED – solid red
  • Rear LEDs – The LED corresponding to the original disk will be blinking blue and the one being synchronized is blinking red
  • Once both disks are synchronized, their corresponding rear LED and the front LED will be solid blue.
