So my tv has worked fine for about a year or so and then it stopped working, wont turn on so i left it alone and unplugged for awhile thinking i needed to get a new oe then a couple weeks has passed and i...

It most certainly a power supply issue. If the board is separate you might find one reasonable, but some are all-in-one boards and only a technician who knows how to repair the electronics will help you. most of these are bad capcitors

No red led on front panel & wont power on at all

Check the wall outlet to see if you have power going to the TV. Next, the case will need to be opened; look inside for a fuse near the power wire. Beyond that you will need someone with TV experience to help you.

My RCA HDTV wont turn on can u help

HI Kenya - Have you checked to make sure that the outlet your TV is plugged into has power? If not, unplug your TV and plug something else in to see. If there is no power, then you have an issue with your circuit/breaker box. Have you tried your remote control (will charged batteries) and tried turning it on manually from the front of the TV? If you've tried all of these things and they are fine, then it is something internally wrong with your TV. Unless you are willing to take it apart and figure out, you will need to take it for repair or replace it. I am sorry, but there is no simple solution without knowing more detail about it.

My sylvania LC195SLX 19" TV

You will have to open the back of the television to repair the television, and care must be taken by unplugging the power plug of the television.
A common problem for these is bad capacitors in the power supply, Remove the back from your Television and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this help in solving the problem and do take care because it contain high voltages

Try unplugging it for about 30-60 seconds, then plug it back in and before you turn it on, make sure there is a good video source going to the TV either from Satellite/Cable or a DVD player or something.

If this doesn't work, try unplugging it a bit longer and then plug it back in and try again. If it still does not work, you may have to take it in and get it serviced.

Usually when devices power themselves off like that, there's something wrong...

I hope this helps :) Good luck!

Best Regards,
