Question about Televison & Video
1, changing the fuse. 2, Using manual control on TV
Check that the power cables were properly seated to the power board internally. If your TV is not starting at all, then likely this occurred, or that the cables are not seated properly to the TV. Any number of things can happen when you do servicing to the TV, assuming that had happened.

I called the factory or the distributor or wholesaler (customer service) that comes out on the web and they told to just buy a new remote cuz tv just isn't recognizing the remote. Can this be true? If this is far from being true, where do I buy the boards and what are the chances that the boards are the real problem?
thanks once again.

Check or have a repair tech check connectors AP1 and AP2. Vibration rattles the power supply board (a crappy design, as the board is almost "floating") and causes the wires in the connectors to break, and may make intermittent contact. Heat may also cause intemittent contact. A very common flaw.

It sounds like a shutdown circuit is being activated. This is normal in cases where the power supply id drawing excessive current. I would suggest that you get this looked at by a qualified professional. This is because this problem may be in the power supply and the voltages can get dangerous in this section of the TV set.
In any event if this is a power supply problem chances are the technician will just have to replace the power supply. Which should cost from 150-250 dollars.
I hope this helps

The above fix, listed by Tom saved us!! We did as instructed and took off the back of our 50 inch Magnavox plasma tv. We were not sure what we were looking for so we googled capacitator (image) & there was a photo of a fried capacitator! Sure enough we noticed ours were "fried", we took out the board and went to an electronic supply store, bought the 2 capacitators ($2.00 each!!) and then found someone who did tv repair to sauter the new capacitators onto the board. (It is important someone who know how to sauter and recognizes polarity do do this for you) All in all we fixed this following the above instructions for $34.00 and our time. For a month we were told to spend hundreds getting a new power board!
Kudos to you Tom & thanks so much!!
