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!

TV no longer power's on. What problem is causing this condition?


If the TV AND the DVD player are not powering on, then it sounds like the problem is at the receptacle or power strip, where the TV and the DVD player are plugged in. Make sure the receptacle or power strip is working. Plug something else in, a lamp, a radio, anything, and see if it works. If it doesn't then the power strip is off or not working or the wall receptacle is not working.

After you turn it on it goes to a black screen, then wont turn off.


first check the supply of the LCD monitor check the plug supply usually 110V or 220v use a voltmeter, if the voltage is present look for the indicator lights that is changing when power switch is press,the indicators tells you if the problem is in the power supply area of the LCD monitor or in the screen, usually the problem with the LCD monitors is in the screen check the bulb on top of the monitor check if it is not function well this bulb is responsible for the brightness of the screen if it is defective replace it or maybe the supply of the bulb is defective you can use the power supply of the cathode light as a replacement to its supply that is usually use in motorcycles signal lights.. hope this helps you..

Tv wont turn on, i got it last april, it worked eversince,


First off, try a power drain:
Unplug the TV's power cable so it is not grounded to the house.  Then press and hold the TV's own power button in for a minute.  Plug the TV back in and see if it works. If it sill won't work, are there any visible LED lights you can see in the back of the TV?  You need to determine if the TV's power supply is shot or the TV's mainboard.  Service would likely be required if the TV still won't turn on.

Code needed for a Electrohome tv


The Product: Electrohome 27E510

The Problem:
3rd Party Universal Remote when trying to "scan" for correct codes inadvertently activates a diagnostics setting on the TV set.

The Symptoms:
The word "FACTORY" appears on the upper left quadrant of the screen in RED letters & suddenly all controls are "Locked Out." Television will not respond to button presses on original remote or on it's built-in-buttons on the side panel. All settings/options are "Locked Out" & the TV can only be shut OFF by physically unplugging it. Additionally, when the TV is plugged back in, it is still in the "ON" state & remains in "Locked Out" state.

The Solution: (thanks to a couple of hard-working Support Personnel at NESA)
Plug TV back into power source. Wait until it powers up and the word "FACTORY" is visible on-screen.
Press 6-4-8-3 on the TV's ORIGINAL IR remote device.
You are now in the diagnostic settings Sub-Menu, & the word "ADJUST" will be on the screen.
Press "MENU" on your TV's ORIGINAL IR remote device.
The TV is now back to it's former fully-functioning state.
