When i try to turn the tv on it does it just clicks over and over

I have a proscan 55LC55S240V87 Ive had it for about one year. When I turn the TV on it takes much longer to turn on and the screen lights up in the back ground but I get no picture only sound on and off. With the TV on I pushed the function button on the remote and the TV gave me the option of what connection to go to and I choose HIMI 1 and the TV worked Great till I turned the TV off. The next day when I turned the TV on again it took a long time to power on then the screen lit up in the back ground but no picture at all only sound off and on again. I installed a new HDMI cable but that did not fix the problem, and now the remote function button does nothing it will not give me any input options. I tried a differant identical remote but TV still has no picture nor will it give me an input options and it still takes a long time to power on.

Hello,

Hi
A common problem for these is bad capacitors in the power supply, Remove the back from your TV 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 helps

I have a proscan 36" dual hdmi tv n my power went out n now i have no sound to the tv
