Yeah I got the Olevia 537 and I was trying to set it up without a remote and I got that first screen where it's at just chill room and power up and I can't get out of it I turn it off on unplug during everything I cannot get rid of this that screen is there a way I can do it or we do a hard reset somehow

You will need the remote to do this. If you can't find the remote get a universal remote with a video or input button on it. The other set may not be the same model and has different features.

Olevia LCD 542I - Had the same issue for a week until the tv would not turn on anymore, after several attempts it came back on. A few days later the tv turned off then only the standby light was on, then lost the standby light as well. After researching the problem it could be in two areas, either the power supply or main board. Removed the back and found the power supply had several capacitors that were bulging on the top and appeared the fluid was leaking, all signs of a failed part, removed the PS and replaced four capacitorst that had shown some issues. If you can removed the PS and check for a number on the board, mine was FSP271-4F02, and find someone who has some electronic circuit capablilty, the issue may be resolved at a fraction on the cost of a new power supply.

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!
