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. http://electronicshelponline.blogspot.com/

Will take some trouble shooting. Unplug both the x and y main drivers and see if unit will power up. If it does power up plug one back in and if it power up then unplug and try the next. When it does not power up you have found the bad part. Replace the main and the buffers that are attached to that main and your tv should function.

I can't turn on my 32 inch plasma tv by LG.A green light flashes twice on the power indicator than turns red.


The flashing indicator is telling you the fault. Give the number of flashes to the LG service department and they can help you with your issue. It will likely need service.

LG 42 Plasma try's to turn on but just goes back into "stanby" ?


Check to see if you get Va and Vs voltages from the power supply. There should be some wires running to the y-sus. A couple of those wires will be labeled va and vs. Are they present? There will be a sticker stuck to the panel somewhere telling you what they should be.

I have a lg 37 inch tv when i go to turn it on the green light on the front flicks 3 times goes red and the screen dont come on ?? any ideas thnx matt


I can't tell you if the three flashes identify the problem better but it is with fair certainty a power supply failure. It may be the main power supply or a separate board that produces the high voltage required by the plasma display.
Typically, the parts cost will not be high but the labor may run it up.

Check the power board for capacitors with the tops bulged up. They are 3300uf 10v. There are either 2 or 4 of them depending on your set.
