TV led back-light repair


Tv using power supply unit EAY62810301.

No back-light/sound ok.

No dc voltage measured at P801 led plug.
New board did not fix.
Remove display panel.
With face up, panel will hinge up. (after removing all trim parts) Place folded towels beneath, to prevent strain on tcon ribbon.
Fold other screens up and over on top of display to keep them in right order. Including white background reflector.
Check each series led string with 2*9V batteries and series resistor, minding marked polarity.
Circuit consists of 3 strips of 7 leds all in series.
One bad led disables all .
Check each led of bad string. I used 18V and 1K ohm.
Replace strip or jumper (short) bad led. I just jumpered the bad one that was on edge of panel. (first in string).

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 Gerard,
3 flashes of the led light on most KDL series is a power supply malfunction. To confirm the error code, lets access the self diagnostic screen by following the steps below.

Unplug the unit from the outlet for 30 minutes and then plug it back in and check if the symptoms remain the same. Wait until the led light stops from flashing and then press in rapid sequence the "Display", "Channel 5", "Volume (-)", "Power" button key on the remote control. Self diagnostic screen will be display. Let me know the result.
