Hello,

once a TV does not power on, it is said to have a power problem. The TV still turns on after so many attempts because the damage is not very much. Since it is a power related problem, you need to check those part of the TV that has to do with power such as the AC power cord/wire that runs from the wall (electric outlet) to the TV and the power board inside the TV.

Check the AC power cord/wire, make sure the wire is not damaged in between the part that enter into the wall and the TV. If the wire is intact, then it means the power board is the next to diagnose.

This is the board where the AC goes to. First, check the AC wire and make sure it's not having a partial contact on the power board.

If the AC wire is intact on the power board, then this problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

I do not think the power board needs replacement, rather some defective capacitors are causing this issue.
Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors).
After replacing these capacitor(capacitors) most likely the normal operation will be restored.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

I lost my manual to my ge 24914 universal remote, i need the code to program it to my curtis mathes tv.


Press 'setup' until red light stays on, then press TV once. Press the on/off button (up to 300 times) until TV turns off. Then press 'input' on the lower right side of the remote until the light goes off. It's programed now, I just did this for my mother-in-law. For us, it was about 40 presses of the on/off button.
