Hello, Try removing the battery and fix it back after 5 min. If the problem not solved it has to be the problem with your display adapters or ram.

My 2hp Panasonic is blinking when turn on and the compressor stop working while the outdoor fan will be blowing cool air.


1. Turn power on.
2. Press the CHECK button on the remote controller
continuously for 5 seconds.
3. "- -" will be displayed on the remote controller display.
Note: Display only for "- -". (No transmitting signal, no
receiving sound and no Power LED blinking.)
4. Press the "TIMER" or button on the remote
controller. The code "H00" (no abnormality) will be
displayed and signal will be transmitted to the main
unit. The power LED lights up. If no abnormality is
stored in the memory, three beeps sound will be
heard.
5. Every press of the button (up or down) will increase
abnormality numbers and transmit abnormality code
signal to the main unit.
6. When the latest abnormality code on the main unit
and code transmitted from the remote controller are
matched, power LED will light up for 30 seconds and
a beep sound (continuously for 4 seconds) will be
heard. If no codes are matched, power LED will light
up for 0.5 seconds and no sound will be heard.

Panasonic air con - when you turn the air con on it runs for about 3 mins and then the timer light flashes. Air con will not work.


• Once abnormality has occurred during operation, the unit
will stop its operation, and Timer LEDs blink.
• Although Timer LED goes off when power supply is turned
off, if the unit is operated under a breakdown condition, the
LED will light up again.
• In operation after breakdown repair, the Timer LED will no
more blink. The last error code (abnormality) will be stored in
IC memory.
• To make a diagnosis:
1. Timer LED start to blink and the unit automatically
stops the operation.
2. Press the CHECK button on the remote controller
continuously for 5 seconds.
3. "- -" will be displayed on the remote controller display.
Note: Display only for "- -". (No transmitting signal, no
receiving sound and no Power LED blinking.)
4. Press the "TIMER" or button on the remote
controller. The code "H00" (no abnormality) will be
displayed and signal will be transmitted to the main
unit.
5. Every press of the button (up or down) will increase
abnormality numbers and transmit abnormality code
signal to the main unit.
6. When the latest abnormality code on the main unit
and code transmitted from the remote controller are
matched, power LED will light up for 30 seconds and
a beep sound (continuously for 4 seconds) will be
heard. If no codes are matched, power LED will light
up for 0.5 seconds and no sound will be heard.
7. The breakdown diagnosis mode will be canceled by
pressing the CHECK button continuously for 5 sec-
onds or without any operation the remote control for
30 seconds.
8. The LED will be off if the unit is turned off or the
RESET button on the main unit is pressed.

When you have the error code, we can work out what to do next.

The green light on front of my HP computer comes on for a couple seconds and then it goes to red light blinking and beeping try to turn off and back on several times and go right back to blinking red


test all leads that attach to your hard drive including electrical extensions SATA

the leads from your (motherboard to your hard drive) make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty


make sure all leads that are attached to your drives dvd\cd have secure connections and are not faulty


even something as small as an electrical extension or a faulty fan lead can cause you problems computer needs all of the data and power to travel through every working device and to have an end for a computer to be able work properly


a motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive check all electrical extensions make sure they are securely seated even the cd/dvd drives need to have current go through make sure these devices are working


check the CPU make sure it has thermal paste and dust free secure seating


also check your computer ram modules and cmos battery make sure they are dust free and securely seated some motherboards cmos batteries are soldered in


hope it helps

When i try to open the only respond i get was the continue blinking of the laptop no picture is benig showned in the monitor


Shut down your laptop and try pressing the center of the keybord just center of your screen firmly gently and then start the system if its ok the display comes back you are having problem with the heat sensor of the display card and not coooling properly .so loosing the display.
BUT if you mean there is a cursor blinking on the screen and dosent have display then your boot devices are configured improperly and so its searching for boot device .
also it happens when usb boot is enable in the bios and any usb device is connnected like flash or usb hard drive try to remove them and restart the pc.

My tv sony wega dont turn on an the standby light blinks 16 times model KV-32FV310


Hello
Standby light on Sony TVs blinks 16 times is abnormal I thiks. It may come up to 8 blinks or so. You jsut switch off the set by AC mains switch at the front panel, switch it again with it and count the exact numbers. Never switch it On_Off by remote hanset.
If it happens even after this process, you just do the following
Press the following button on your remote control as stated
"Display"_"Channel"_"5"_"Vol Minus" [not plus] then "Power".
You may get "OVP" "OCP" "V STOP" etc displayed on the screen.
Just report the result to me through Fixya. Ok.

Blink screen


do the lights on the laptop come on (does it have power?) if they do connect the laptop to an external monitor if you get a normal display thats good its sending a signal try pressing FN + F4 it should toggle between normal and external display modes... if that doesnt work you may have a problem with the motherboard.. either an unseated cable or short circuit...
