Having problems with your Flat Panel Televisions ?

I have a Samsung LN40A550P3FXZA that is giving me problems. When I first started noticing problems I would turn the TV on and I would hear the power-up sound, the backlight would come on and then the red LED would flash a few times then the backlight would go off and it would repeat (power-up sound---backlight on---LED flash---backlight off). It would do this several times. Sometimes I would be able to get picture if I hit the source button on the side of the TV when the backlight first came



Answers :

Try Samsung parts. They will almost always have the parts. As for the price. Its either 175$ for the board or a new tv. You have no other option
Wow, your having some issues and I feel for you. The problem you describe as I see it, sounds like a bad capacitor leaking and causing severe interference with the circuitry. As you know Samsung has had several issues with capacitors and for what ever reason they are ducking the problem as best as they can. Do you have an Ohm meter? You can test the capacitors on your board to see if any one fails, they don't have to look blown to be bad. The bad part is you have to disconnect at least one end of the capacitor to do the test. \015\012\015\012

Discharge the power supply stored in a capacitor prior to testing with an ohmmeter. Touch both terminals on the unit with a metal screwdriver that has an insulated handle. The connected circuit formed by the screwdriver blade against the terminals will drain the power.
\015\012\015\012

Set the ohmmeter or multimeter for testing. Set a multimeter to an ohm setting in the high range. Turn the meter on, touch the leads together and set it to zero with the calibration wheel.
\015\012\015\012

Touch both terminals with separate meter leads. Watch the needle motion. The needle should swing to the right a couple times and then rest on the infinity mark on the left.Reverse the leads. Remove the ohmmeter leads and place them on the opposite terminals. The needle will swing to the right again before resting on the infinity mark if the capacitor is good. The needle will drop to the zero mark on the right if it is shorted out.

Any shorted capacitors will screw up the set. If you find one bad my recomendation is to go to radio shck and get a new one, these seem to be a much better capacitor than what Samsung uses.

Power Surge After house power went out and came on 20 seconds later, my Pioneer would not power back up. It has two LEDs - the blue "on" LED flashes 12 times on, pauses, and repeats the sequence over and over. I tried powering down from the switch and even removing AC power entirely for a couple minutes. The best it would do is to go thru it's normal power up sequence, show a "starting up - please wait" screen for a couple minutes, and then shutting back down with the blue LED flashing.

Samsung PN50B450B1DXZA will not power up. When I try to power it on, it makes a clicking sound and then nothing for 10-15 seconds and another clicking sound.
