Power supply failure

When an abnormality has occurred the unit, the protection circuit operates and reset to the stand by mode. At this time, the
defective block can be identified by the number of blinks of the Power LED on the front panel of the unit.


Hopefully it eventually stops blinking after unplugging set from the outlet, otherwise claim your Nobel Prize for wireless energy transmission.

The set has an internal fault and needs to be serviced

Same issue with - Panasonic TH-50PX70A , power UP with red standby, then power ON by remote - only Gives GREEN led blinking 35-40 times, followed by solid green led with no no picture no sound.
>> Solution; unplug Plasma from AC 10-15min, then plug in & power on to Red standby led,, At this point - Power ON tv while holding down both -Volume Down and F (function Select) buttons (front panel door) at the same time turns picture ON,all ok.

TH-42PZ77U:
There are different patterns for blinking light...
10 times indicate DG board problem - SUB 5V SOS, MAIN 3.3V SOS, DTV 9V SOS and Tuner Power SOS.

the blinking led is a error code. Let me know the number of blinks and I will assist you.

if the led is blinking three flashes, thats the error for the convergence . You can get the convergence repair kit for your model at www.tvrepairworld.com and the kit contains the parts and the CD with detailed instructions

3 blinks is the error code for the convergence ICs. You need to replace both STK392-110 convergence ICs. You can get replacement ICs at the following link and they provide installation instructions with pictures.

Good Day;

Bad news this TV has multi problems, check these:

1. Red status LED, self-diagnosis error 44, check for open F9A06 on the Power PCB part # 283P128050 on the Power PCB 2. Red lamp LED, self diagnosis error 34. Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if missing replace the Power PCB part # 930B921002 3. LED stops blinking after 70 seconds of plug in but will not power on. This model is equipped with a keyboard lock feature, this can be mistaken as a no power condition. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds 4. LED stops blinking after 70 seconds of plug in but will not power on. Check for 3.2 volts DC at connector LE pin 3 and 4 on the Control PCB, if low suspect problems with the switches/buttons on the Control PCB part # 935D776001 5. LED stops blinking after 70 seconds of plug in but will not power on. Keyboard is not locked and key inputs at connector LE pin 3 and 4 check good. Suspect the E2P PCB part # 934C121001 6. (LED does not stop blinking after plug in) Disconnect the USB connector from the card reader to the front from the Chassis, if the LED stops blinking after 70 seconds replace the Card Reader part # 299P271010. 7. (LED does not stop blinking after plug in) Disconnecting the USB connector from the Card Reader did not help. Remove connector FC from the FMT PCB and plug the unit in, if the LED stops blinking after 70 seconds with FC removed suspect a problem on the FMT PCB (part # 930B924002), if the LED keeps blinking with connector FC removed suspect a problem on the DM PCB (part # 934C116002). 8. (LED does not stop blinking after plug in) On the DM PCB (part # 934C116002) check C81A2, C81A3, C81B3 and C81B4 (1000 UFD, 16V, 105C), if any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C). See Service Tip VS-78A 9. (LED does not stop blinking after plug in) On the FMT PCB (part # 930B924002) check C8F19, C8F21, C8F22, and C8F27 (16V 1000 UFD 105C), if any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C). Good Luck, big IRISH.

Yes you can first try this:. Red status LED, self-diagnosis error 44, check for open F9A06 on the Power PCB part # 283P128050 on the Power PCB 2. Red lamp LED, self diagnosis error 34.
