    Which fuse is blowing? Do you mean your breaker fuse for your house wiring? If your breaker is popping, then there is something internally wrong with the RCA TV, like a short circuit in the wiring).

You might look at this FixYa link:

Do you still have the original fuse? There is numbering on there that shows the specifications. You probably need a slo-blo type fuse, 3A or so, but I can't be sure on that.

    Try this link:

    I would get the fuses from Radio Shack.

    One of these should do the trick

    If the fuse keeps blowing, even though the correct type is installed, then there is another problem (probably with the power supply) that is blowing the fuse.

  • Mike McWhinney Jan 23, 2009

    The power supply is inside the TV. It has the transformer.

    Check this link:

    You might contact RCA for information on repair/service for this. Otherwise if there is someone locally that can take a look at it (like a TV repair shop). I would not spend more than $50-80 to repair it.

    In general, a transformer/power supply will look something like this:

My tv wont turn on when i push the power button it ticks??? what coud be worng

if your tv is not powering on, firstly check the switch contacts, rectifier diodes, power trsnsistor, fusible resistors and zener diodes. all these components are at power supply section.

make sure that a HT voltage of 90-115v, shows at the line transister near the line transformer.

note-----a tone be head on the supply.

I have an RCA model 20F512T and the screen is tinted green

maybe you should check your picture settings from the menu button, it should be a "slider" from red to green, and your preference somewhere near the middle.

It takes a star driver if I am not mistaken to take the back off probably two different sizes one for the top bottom and sides and one size for where the rca jacks are.. I only recommend checking the fuse...if blown never put foil around it. Takes a 4 amp. 5 amp would be ok. Dont go over this. If the fuse is good you should take to a good tv repairman. If blown and blows the fuse you put in take to tv repairman. Anything past this is highly technical. Hope you have a blown fuse only.
