There is probably a bad capacitor on the power board, I had the same thing happen to my 42LB1DR after 2 years. T.V. would turn on and white power light would blink, no pictue and no sound. If your'e a diy'er, it is not that hard of a fix. Take all the covers off of the back of the tv(UNPLUGGED!!!), then look at all the capacitors on the power board. lcd_repair_4_bad_capacitors_lg.jpg
These are the capacitors, look to see if any of them appear to have a bump on the top of them. They are supposed to be flat, you can also tell if one of them has gone bad if there is an oily substance on the metal cover that was removed. If one of them is in question, carefully remove the board, and take it to an electronics store to have them sotter ?sp on a new capacitor. It ended up costing me around $40.00 to have this done. Good luck and if you are not comfortable trying this, than take it to a repair shop, but I was quoted around $450 to take the T.V. in. No Thanks

SOURCE: LG TV 32LB9D VOLUME STUCK AT 100, NO RESPONSE TO REMOTES

The fault may be on the control board. Sometimes the button switches can be stuck, or there may be something causing some conduction on the control circuit board. It is also possible to have a component failure that is causing a continuous command to keep the volume to the high position.

Something that causes failures of controls in TV sets is when people clean the screen, they spray liquid cleaner on the screen. Some of it drips down in to the controls and on to the circuit board. This will usually cause damage, and thus the set will require shop service.

Whe you press the power button the TV led have to blink several times and the it have to change to blue, meaning Tv is on.
If you press the power button and the led start blinking and goes off, then you need to replace the mainboard because it is damaged.

How to repair lg 42 plasma, turn power on and blue light flashes 3 times and goes back to red, will not turn on, see little red and green lights flash on board


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.

My LG 42LH30 gets red power light but wont turn green?


Fault with main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

No display issue


Red means it is going into shutdown because something is wrong.

It will not come on again until problem is found and corrected.

What is model number and do you have a warranty?

The screen doesn't go on when the power to the TV is turned on.


View your screen from a flat angle while on a known active channel to see if you can detect any 'ghosting' of images.
I think either the back-light or the high voltage supply for it has failed.

Back light comes on nothing else


This is indicative of a bad main board that will need replaced. For this model make sure the repair person has the full product code (from the back of the unit) so that they can get the correct main board ordered (there are multiple versions depending on the product code). Hope this helps.

Hitachi Plasma TV model P50H401


I think you have problems with the digital main PWB.

If the power PWB failed, turn off and change the pilot ligth to red.
