Model - 42LG30D-AA power indicator flashes red 3 times then is on (blue) but screen is blank it also turns off with indicator is red ....checked power supply & lead..ok. Any ideas pleas?

1. Check that the power is turned off

2. erform one of the following operations depending on the connection status. When connecting for the first time
Hold down button for 3 seconds until the indicator flashes alternately in red and blue.
When there are 2 or more the BLUETOOTH devices to connect to
Hold down button for 5 seconds until the indicator flashes alternately in red and blue.


3. Turn on the Bluetooth function of the BLUETOOTH device.




4. Select "JVC HA-S20BT" from the device list.




5. The indicator flashes slowly in blue when a connection is completed.



Please note :

During the pairing process, the BLUETOOTH device may require input of a PIN code. In such a case, enter "0000" as the PIN code for the System. If connection (pairing) is not completed within 5 minutes after the indicator starts flashing, the System automatically turns itself off.

Cheaper to replace than fix, trust me on this.

Take the screen off connect power and watch LEDs if any don't flash its LEDs only needed to change faulty strip if they all flash its probably t con boards.

Indicator Lights:
1.Headset Status Headset Indicator Light
2.Powering on Steady blue, then intermittent flashes
(changes to standby mode)
3.Powering off Red appears and goes off
4.Standby Blue intermittent flashes
5.Charging battery Red solid light. Light indicator turns off when
battery is fully charged and headset is off.
6.Low battery Triple red flashes
7.Pairing mode Blue/red alternating flashes
8.Missed call Purple flashes. Press the call control button
to cancel flashing light.
9.Incoming call Triple blue flashes when ringing.
Power on and off:
1.Turn on the headset Press and hold the call control button until the
indicator glows blue. You will hear ascending
tones.
2.Turn off the headset Press and hold the call control button until the
indicator glows red. You will hear descending
tones. When power is off, indicator stays off.
If none of this is helpful then it may be that your battery is dead, if that is the case then you will need to replace the whole headset. The battery's are not replaceable.

Good luck from Headsets Direct!

What color is the power light when the system shuts off?

Red: If the power light is red, or flashing red, when the system turns off, then the system's battery needs to be charged.


Blue: If the power light is blue when the system turns off, then there appears to be a problem with the system and it will need to be repaired.

If the orange recharge indicator light blinks while the system is plugged in and charging, then it is likely that the battery is not installed properly.

If you have ensured that the battery is installed properly but the orange light still blinks, check to make sure that the battery is a licensed by Nintendo. The only licensed Nintendo DSi battery will have the model number "TWL-003" (Nintendo DSi) or "UTL-003" (Nintendo DSi XL) and will display Nintendo's logo.

Pls check that model number........the problem description does not match that of a 1999 crt proj tv.........I believe yours is a newer lcd projection around 4 or 5 yr old?? Lamp light flashing on any brand is indicative of the lamp not lighting . The lamp is the most likely cause,but the ballast board can cause this as well..................you should see an access door refer to owner book of the correct model and you can replace yourself...........it may cost around $200 and avaiolable at encompass parts .com Hitach distributor

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Please post back what you find.

Do you have a green light that flashes and then goes off? You need instalation kit# 4835 310 57673, The chassis# is probably an L04.1U AA, correct? What you will do is correct the horizontal timing so everything will come on at the same time. After you install you will see red, blue, and green horizontal lines at the top of your screen.......this is normal when you power up your TV. This is a factory authorized repair.
