Panasonic pt53wx53 led blinks once


unplug the set---where smoke something has burned.

I would with back off have a look---look at high voltage transformer and that area of board and pay special attention to C509 (brown cap in front of high voltage transformer about 2 inches---it will be marked with that C509 on board.

If it is cracked or burnt it is bad---these fail a lot.

If the set needs to be worked on it has a lightbox---about 8 bolts removed and entire guts or chassis comes out in one piece--can be powered up out of the cabinet.

Let me know if need more information.

Powers up , has audio but no picture


Plasma sets have two separate power supplies; the main supply produces voltage for everything and may even produce a specific voltage for the high voltage required by the plasma display.
In your case, it is likely that the latter (HV) supply has failed.
This may be a separate board and if so, may be user replaceable since these are normally outsourced and just plugged into the set during assembly.
Removing the back of the housing, you are likely to see at least three boards. One of them (the main board) will have many components and most will be smaller in size. The main power supply will have much larger parts on it and the high voltage supply will likely be connected to it and have far fewer parts than the other boards.
It is possible but unlikely, that the main power supply is not providing voltage to the HV board for the display.
If replacement of the HV board doesn't restore the display, then it will be necessary to replace the main power supply too.

Just yesterday, my Panasonic TH-50PX75U HDTV Plasma Television has only the lower half displayed. The upper half "flickers" but for the most part, dark grey/black. wtf


There are several possibilities here. Four different boards are involved in the horizontal scan of a plasma tv. The most likely order of failure for what you describe is; SC board, Su and SD, and finally the SS. These are Panasonic's names for what are more commonly known as the Y Main (or Y-Sus), the upper and lower Y buffer boards, and the Z main (or Z-Sus). Sorry I can't boil it down any further for you,... would have to measure voltages, etc.

I have a Panasonic 53" PT-53x54- 53" turns on for 5 seconds then


It is very common for the high voltage tranformer or flyback to wear out and not provide adequate power to the tv. You can test them with an ohmmeter to see how much powrer is being sent to the main circuit board. You can get parts at tigerdirect.com

On my Kenmore Elite Bottom Freezer Refrigerator, the display on the left door reads ErCo and the ice maker does not work . Its less than 2 years old


The Er Co error code signifies a communication error between the display control board on the freezer door and the main power board on the outer back panel of the refrigerator.

Check the wiring and connections between the low voltage interface and the main high voltage board.

If you are able to unplug the refrigerator and remove the cover over the control board on the back of the refrigerator,
you can check the wiring connection on the main control board.

If this wiring connection is okay, check the wire harness connection under the hinge cover on the top of the left hand refrigerator door.
If these connections are okay, then you will need access the wire harness connection in the dispenser.
