Question about TCL Televison & Video
I press the button on the television to turn it on and the red light goes out like it is going to turn on but doesn't turn on for hours after sometimes. Sometimes when the power button is pressed the red light goes out like the tv is going to turn on then goes back out. Have to keep pressing the power button until the red light goes out and stays out until the tv turns on hours later. Sometimes the tv wont turn on until 8 hours later after pressing power button and red light goes out.

if you replaced the supply board then there is issues with the decoder board as you would need to chec kthat and see if its not the issue.

I have a 24" Olevia LCD TV. Same symptoms (Stdby LED is on, press power and it flashes off, then back on). The USB cable to the Service Port also worked. But being of sound technical mind, I figured this means that the PC is supplying the +5v to the circuit. What I did was disassebled the TV, carefully disconnected all the cables, and opened it up to reveal the circuitry. I looked over the circuit and noticed the 1000uf/16v capacitor at position CS21 was failed and bulging. I removed the cap, tested it and verified that it was indeed failed. I went to a local Radio Shack and picked up a 1000uf/35v electrolytic, after all, the value is what mainly matters as long as it's not lower voltage than the original. I replaced the new CS21 capacitor back in the circuit (it is polarity sensitive, so pay attention to what the original mounting position is). I reassembled the TV and Viola! Works! No need for the USB cable to the Service Port!
I hope this helps someone!

Symptoms of a Defective or dying Power supplies on LCD TVs. 1. Light(s) on the front panel are behaving not normal example, blinking, amber color or not steady, fainting, etc. 2. TV not turning ON properly. 3. TV turns OFF by itself. 4. Needs to be unplug to many times to make it work. 5. Humming or high pitch noise heard through speakers or at the back of the TV. I repair these power supplies. Write to [email protected] if you require further assistance.

SOURCE: does not turn on
Most likely a blown capacitors. Take off the cover and examine the capacitors on the main power board. If they are bulging or leaking they need to be replaced.
