    Replaced the PS. Ran for maybe 2-3 hrs. When I turned it on this morning it ran 10 secs. and now again no a/v. Found a service manual online and managed to get it to the csm mode long enough to get a error code of 04. Any ideas? THX

    error code 04 is new to me, but I've seen 05 many times it usually means that the firmware is corrupted. I would see if there is firmware available for your exact model. If your model came with a usb port then it is easily installed by unzipping the firmware file to a thumbdrive. turn on the tv let it sit for 10 minutes or so and it should be installed.

    (make sure NOTHING else is on the thumbdrive but the firmware).

    if you cant get the firmware or the installation doesn't work then you might try to to replace the SSB (small signal board) Located along the Bottom Middle in th back.

LG 50PC5D-UL plasma tv not getting a picture.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
Blinking codes details of many popular brand TVs are given. Surf the site with patience.

Turn tv on. green light solid display, no picture or sound

The flashing green light is likely indicative of a self-test failure, indicating the TV has detected some sort of internal fault. With no picture or sound, one strong suspect is the power supply. Flat-panel TV's have an internal DC power supply that converts the inbound AC current, and when these fail, or are unable to supply a minimum level of power to the set, it can behave as you describe, providing only enough power for the green light to illuminate.

No pictur or sound p50hdm

Do you have an amber pilot light? If yes power supply is working.

If amber light turns green when power button is pressed then set is turning on. If not then you problem is most likely on the main board, the panel that has all the inputs on it.

Is the monitor set to an input with audio Set defaults to AV1 input when power is removed. The most common problem with this set is sound ok no picture. This is a display problem usually Y or Z sus boards.

If it is truly no sound and no pix then the problem is in ether the power supply or the main board.
