When i turn my 32'' rca flat screen on the red light is flashing but it would not come on ,what is causing that to happen ?

Bad caps in the power supply. Replace all bad cap or replace Power Supply Module. If you choose to try and fix it yourself yourself will need a ESR Meter to check the caps in circuit. Let me know if this helps.

There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
If you repeatedly turn it on, eventually it'll probably stay on, but every time you turn it off, the TV will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for 5 mins, then try.

If you aren't tech savvy, this unit needs to go in for repair.

If you are handy with a soldering iron and can identify the power supply and inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for different brand, but same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors.
The parts are cheap, and skill required is minimal.

sounds like it needs new caps on the power supply board..............easy fix if you can use a soldering iron........
cheers
