Tthe blinking light is a code to give you an idea of what the prolem is. The code is descrived in the service manual for this tv. You would have to do a search on the internet for the service manual there should be a few people selling it. This TV is very simply so it's either going to be your power supply or your signal board. You can get parts for this TV at www.interliquidparts.com

Testimonial: "Combining the different answers, I checked the inverter IC (P2503) containing two complementary FETs: one of them was leaky and the second one was short circuited. I have found an equivalent IC (couldn't get the original one): FDS8858CZ which I put in place and the TV is back in the race ! Thanks a lot for your useful hints and your great job !"

SOURCE: power led blinking red and green wont turn on

For LG DU-37LZ30 specifically - On the power supply board, look for IC101, an 8-pin DIP IC. There will be three smaller electrolytic capacitors near it (C107, C113 and C125) marked 47uF, 35V. I'm being lazy here, but replace all three (only one is the real culprit). What is happening is that one of these caps is charged by line voltage until the IC (power supply controller) can start running. When this capacitor gets leaky, it cannot reach the proper voltage to start the controller. I used a 47uF, 50V replacement.
I have fixed two LG sets with this same problem. The other was a 26". It's a cheap fix!

SOURCE: LED blinking RED and BLUE

It may be in the safety shutdown due to bad power supply, bad backlight inverter boards.
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.

SONY KV-29CS60E LED BLINKING 14 TIMES


It is unusual. Count the blinking codes once again.
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/
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

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.

Hi I have a panasonic split air conditioner. It turns itself off immediately after turning on, the timer button then flashes and that's all.... I have checked for an error code it is H00. I have also made...


Hi Tania,
Have you gone through this checking sequence.? it's from a Panasonic a/c manual. It could be something as simple as a clogged filter. Once you have rectified the fault, you will probably have to clear the fault code as described at bottom below, before it will condescend to work again.

My 73" mitsubishi dlp WD-73827 turns off and has a red status light blinking. I have replaced the bulb and the heat sensor... any answer to what else could be the problem?


It is helpful to have the sequence of the blinking red light. This may help:

MODELS: WD-52627 / 52628 / 62627 / 62628 / 62827 / 62927 / 73727 / 73827 / 73927

Page 43

3. Error Code Operational Check

Note: The TV must be in "Shut Down" and not have been switched Off, to perform the Error Code Operational

Check. When the TV is switched Off, the code automatically resets to "12" No Error.



Pressing the front panel "DEVICE" and "MENU" buttons at the same time, and holding for 5 seconds,

activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem

has occured since the last Initalization.



Note: The front panel buttons must be used, NOT those on the Remote Control.



• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.

• The flashing then pauses for approximately 1/2 second.

• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.

• The Error Code is repeated a total of 5 times.



Example: If the Error Code is "23", the LED will flash two times, pause, and then flash three times.
