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 section 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 procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

Why does it have six red blinking lights?


Hi Tim
In my opinion
No... the LED's are doing their job
Error reporting
Modern TV's are computers and try to indicate where a problem exists.
Does it need a Firmware upgrade?

Red green or orange lights are on or blinking on the TV

Flashing power light


Fault with serial data; serial clock signal path. Serial clock path is OK, but data path must be traced. Seek tech support. This is a very skilled work.

I have a quicksilver power mac G4 desktop that has a blinking green light when I turn it on. What should I do?


I assume the light you refer to is the power LED.
No Apple tech repair guide says anything about this LED being able to blink.
It's possible that this is an indication that it is trying to upgrade firmware, especially if it is accompanied by a loud audio tone of about three seconds. I can't say this for sure, because it has never been necessary to activate the firmware upgrade mode on a Quicksilver, since Apple never released any firmware upgrades to it. Firmware upgrade activation is achieved by holding in the power button at startup until the tone is heard. If you are hearing the tone and the power LED is blinking, it may simply indicate that your power button is sticking in.

My colour printouts from new Samsung CLP-310 do not match original WORD 2000 docs colours (or compared to HP deskjet. Is there a MS patch for this?


Hello,

There is an update for your printer. This is a firmware update. A firmware update, rewrites code located on the printer's main system board. The latest update is dated 10/17/08.

Flashing firmware does not have a go back element or undo, so it is really important that we verify your model and what seiries of printer you have. I suspect you have a CLP-300 Series printer and that the 310 of the 300 just describes some features added or left off and even who you purchased it from, in many cases.

Please look at these two photos and then post the data off the name plate for your model number in particular.

You will notice there are two lines to include in your reply.
1.) The Model: (first line)
2.) M/C entry (second to last entry in this photo of the label.

Once you verify this and I post the firmware update link for you, you will need to follow the instructions I include below.

Regards,
Worldvet


[from Samsung.com PDF file on this firmware upgrade]

Samsung has released a new Software upgrade file for print quality, automatic error recovery, and toner save mode on color laser printers.

Procedure to Set-up Download Mode on Your Printer - CLP-300 series
Turn power off.
While holding down the ‘STOP’ button on the Printer, turn the Printer back on.
Keep holding down the ‘STOP’ button until all the LEDs turn orange.
Then release the ‘STOP’ button, and press it again, one more time.

1. How to Upgrade
Please make sure to check the printer model number before performing the firmware upgrade.
2. Release Notes
Improved on light printing quality at low temperature environment
Automatic error recovery at abnormal operation
Toner save mode by optimized toner supplying
3. Caution
After firmware upgrade is completed, green LED lights will light up.
Do not turn off the printer before green LED lights turns on. A power interruption will corrupt the process.
If the printer is connected by a USB cable, disconnect all other USB devices, except your keyboard & mouse, from the computer.
If possible, be certain the Printer is connected to a BackUPS

Firmware Update Confirmation Instruction
Model CLP-300 series
When firmware upgrade is started, status LED light will start blinking.
As the printer reinitializes, status LED light will automatically turn off and then on.
Firmware upgrade is complete when status LED stays on green.

After firmware upgrade is completed, the LCD will display the message ‘Ready Copy’ and the LEDs will stay on green.

4. If there is an Error after firmware upgrade
If LED is on red or blinking after firmware upgrade, set-up download mode again and re-try the firmware upgrade.

We had thunder storms my tv 65613 has a green blinking light wont star


Good Day,mikeybecerra; TV wont come on mb try these 6 items, please pay attention to the blinking light (it's a code) : 1. Check for no 8.4 volts DC at pin 3 of PC9A10 on the Power PCB, if low or missing replace PC9A10 part # 268P058020. 2. LED does not blink at plug in. Check for 3.3-volts DC at connector RF pin 3 (system reset) if low or missing suspect the reset switch S7L20 part # 432P109010 on the Control PCB. 3. LED does not stop blinking after plug in. Verify the standby supplies, 12-volts at connector KA pin 17, 6-volts at KA pin 18 and the 28-volts at KA pin 19, if the supplies are present suspect the DM PCB part # 934C067001 4. LED does not stop blinking after plug in. Check C9B01, C9B02, C9B10, and C9B11 (1000 UFD 16) on the DM PCB, if they are bad replace them with part # 181P734030 (680 UFD 16 V). LED stops blinking after 70 seconds of plug in but will not power on. 5. LED stops blinking after 70 seconds of plug in but will not power on. Check for 3.2 volts DC at connector RF pin 4 and 5 on the Signal PCB if low suspect problems with the switches/buttons on the Control PCB part # 935D736001 6. LED stops blinking after 70 seconds of plug in but will not power on. Keyboard is not locked and key inputs at connector RF pin 4 and 5 check good suspect the E2P PCB part # 934C061001. Good Luck, big IRISH.
