I found a bulb for my LG for ~ $150 on ebay, easy to fix yourself, just remove the panel on the right side of the TV, unscrew and pull out the little bulb case, remove a few more screws and pop in the new bulb. You just have to be real careful to not actually touch the bulb, as oil from your fingers can damage it once it heats up. Latex gloves work well.

I have the Samsung model: LN46E550F6FXZA, I can hear it power on, the red light on the front blinks 5 times then goes off. There is no sound or picture.


You will need to have it repaired, looks like the inverter board is broken. Google Samsung tv blinks 5 times, there's tons of threads.

Set was on and made a loud pop noise and the picture went off. the red light was flashing and no picture. then it made a strange buzzing type of sound a few times. turned off for a couple mins and then...


It sounds like your screen inverter has just gone >bang< unfortunately.
Most screens inside use 2 main circuit boards, and you are most likely going to have to change one of them.
It's possible also for it to have been just the backlight bulb making the loud pop noise too. The inverter may have given out too much power and blown the bulb (a lot like you hear when a house bulb goes bang).

If you can't actually hear any TV sounds (normal sounds like music, voices etc. when they should be there), then it means the problem is more serious, and would need a specialist repair place to check out the electrical circuit inside.

AKAI 32" LCD HDTV WILL NOT TURN ON


The only solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.
I service these power supplies, for more info write to jah2mil@hotmail.com
