Question about Olevia LT23HVX 23 in. LCD Television
Last night I was using my olevia as a computer monitor. After done with my work I hit the power button on the remote to turn it off. Today when I try to turn it on, it won't come up. THe LED on the tv is glowing. I tried switching the tv off from the back and removing the cable , but to vain. Please help. I also have the same problem. Unit doesn't come on.
Are you still using it as a computer monitor, or are you
back to watching television?
1) Make sure that the you have selected the correct
video input for your programming and that you have
a valid video signal connected the corresponding
2) Does the menu come up when you use the remote?
Make sure that the remote is still in TV mode,
not in cable, VCR or DVD modes.
3) Most TV's will blank the screen to black when there
is no input. If you have recently changed the cabling,
e.g. unplugged the computer
the TV may still be stuck in computer mode,
waiting for a valid video SYNC signal to activate
it from a power saving mode.
Some TV's will also not wake up even to display
a settings menu, unless a valid TV signal is present,
due to idiotic design. (This is now rare for newer TVs)
4) Try pressing the MENU button or the INPUT SELECT
button on the remote, to see if the TV responds.
If it does, select the correct video input and you are done.
5) If the TV does NOT respond to the menu button
(on the remote, or on the TV itself)
re-connect the computer and make sure that the
computer is not in STANDBY or HIBERNATE mode.
Press a few keys on the computer's keyboard,
or briefly press the power button on the PC
in order to to wake it up if necessary.
wait a few seconds....
Does the TV come back on ?
if yes, use the settings menu to change the video input
to normal, before disconnecting the computer,
and you are done !
6) Try all the external video inputs, by plugging in a cable box,
VCR, DVD player ... etc
To see if the TV wakes up
If it does, use the menu to select the correct input,
and your done.
7) Leave the TV switch on, but unplug the power cord
for 2 minutes, to see if it resets.
By leaving the power switch ON, you are making sure
that any residual energy in the TV's power supply capacitors
is fully discharged,
in order to make sure a full power-on reset sequence
8) I you cannot get the TV to wake-up or respond by taking
the above steps, the TV is probably defective and you
may need to contact the manufacturer for technical support.
9) I checked the specs on your TV model, and it appears
that the TV is a true LCD monitor, not a rear projection
LCD chip, so there is no projection bulb to burn out.

Sorry to hear about the trouble you are having with your TV. this seems to be common, though, as seen from the other posts.
This is most likely due to 2 problems -Temperature or a bust capacitor,
1. There is a simple trick...just warm the back of the TV with a hair dryer for 5-7 mins after you have unplugged the TV. Look for the little areas of holes in the back panel of TV. Use these as your guide at where to use hairdryer., but don't hold the dryer too close(say 5-6inches away). (Make sure the dryer is on High heat). If the TV doesn't turn on after you have heated it up (like it tries to come on but then turns off) you need to unplug the TV again, this resets it. And repeat those steps till it works. Reseting the TV after it fails to turn on is the key. Also, just leave the TV on. Don't turn in off. Since it is LCD, it doesn't take much power...only a few bucks extra a month for your utility bill.
2. You can also try plugging in the TV through the USB on its panel to a computer or USB charger, and it may work. However, this is only a temporary solution.
3. If you want to go in for a long term solution, you can easily replace the whole power board (should be about $50 or so). You can call OLEVIA at 1-866-965-3842
or just change the faulty capacitors. You will have to open the back panel and take a look. You can make out which are faulty, because their caps will be swollen on top. Here's a pic:
Check the specifications of the faulty capacitors, and get the replacements from your local electronics shop. If you are comfortable with this, you can use a pair of needle nose pliers to G-E-N-T-L-Y pull out the defunct capacitors. Once that is done, solder in the new capacitors carefully. If are unsure how to do this, try to get a friend who knows how to do this kinda stuff do it for you, or get a qualified technician. Warning: If you do not have a background in electronics repair, or are inexperienced, get a qualified techie to do it for you.
PS. The capacitors are usually 680 - 1000 micro farad and 16-35V.
You can buy the capacitors online from HERE or HERE if you wish..They cost $0.068 - $0.85 each, depending upon the model.
Hope that helps...Should you have any further questions, please feel free to post them here.
