Many of the parts in these sets are proprietory. The manufacture reps generaly change the complete board to service the sets.

The can be failed and you change them, but you would have to also find the cause of the failure. If not, when you apply the power back again, the new parts will fail again!

SOURCE: Plasma went black. Power not interrupted.

Vladislav fixed his TV already by replacing some defective capacitors in the power supply.
The locations of the defective capacitors are C523 and C524. The value is 0.22uF/400VDC or can use 0.22uF/600VDC Polyester coated.
Good Luck.

I think you need to exchange the Main Board.

SOURCE: 32" Samsung TV, No Power or Sound, power LED on, flashes 3 times

Most likely the set has lost vertical sweep or the feedback from that circuit. This will shut the set down to prevent a horizontal line from burning the face of the CRT. This will have to be looked at by a technician.

Samsung 50 Plasma TV- No picture but sound works.


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.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

We have a pioneer plasma tv and there was a loud popping sound and then the screen went blank


I had the same thing happen a few weeks ago to my zenith 50" plasma tv. I tried to turn it back on with the remote and the power button on the set but the only thing that happened was the led would flash green 3 times and then go back to red. I took it to a repair shop and they called yesterday to tell me it was going to cost $700 to fix it by replacing the power supply. No guarantees either that it will last any longer than the 3 years I've had it for either. But it's still cheaper than replacing it with a new "bigger" tv which is what I will eventually do anyway. I've heard of people looking on ebay for repair parts and doing the repairs themselves but there is no warranty on human error...
