Nexus lcd tv won't turn on

SOURCE: new Sceptre 37" LCD TV does not turn on

I just got a 42" komodo by Sceptre, same problem, except "SCEPTRE" showed on the screen. I was sent a USB key program to insert in the service slot in the back and it reflashes the bios. This is old news for you but maybe new for someone?

I just checked and my tv was purchased with a credit card that gave a double warranty. I have to fill out some things but it should be fixed eventually...

SOURCE: Power on problem for My Syntax Olevia LCD TV 23"

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!

replace 2 condensers in the power supply with greater voltage ones.original are 1000uf 35volt...use 1000uf 65volt...99cents each
power circuit is made to fail with typical tv industry tactics...the warranty is reflected by the life of their condensors (capacitors) average life is 2000 hours..
easy...huh
if your a smoker...you must clean the button cover as they get stuck on with your stupid tobacco residue. 75% of all LCD tv's that smokers own fail this way...
\tough huh?
TRY TO STOP SMOKING...
