I press the power button on the remote control and the red led lite blinks on the front of the TV and then turns off and also does nothing. I saw solution #1 but was wondering if theres a service manual with Schematic Diagrams for SP52Q7 TV, i have the user manual/ owners instructions.

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.

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.

Fuser unit failure


Remedy:
1.Replace fuser unit

2.Check the harness connection between fuser unit connector and eject sensor PCB ASSY
3. Replace the PS PCB unit
4.Replace the toner LED PCB ASSY
5.Replace the main PCB assy.

You can try to leave the machine power on for 10 minutes maybe this can clear the error. Or power on the machine while pressing the SW supporter,when the front cover is open and check that toner, DRUM and error LEDs light up, and then release the SW supporter. Check that all LEDs go off and press the SW supporter once,and then this problem maybe cleared by that press the SW supporter once again after all LEDs light up.
