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.
If you want to see photos and a description of the disassembly process and commentary on my repair job, soldering in the new caps, etc. I've posted them online for anyone interested in tackling the job themselves. I've never cracked the case on a TV before, but thanks to some of the hints here, and some efficient Googling, I was able to fix my own set with a screwdriver, pliers and a cheap soldering iron, all for less than the price of a pizza.

PROBLEM: I turned my "Olevia LT23HVX" off the other day and the next day it would not come on. I unplugged it and turned it off for 15min or more like the mfg said and it still would not power on after a day of sitting off it would power on. this is the signs of the power supply going bad and eventually it will just die and not work anymore.
FIX / PROBLEM SOLVED:
very easy to fix if you ever soldered before this is cake!
(6 SCREWS TO SPLIT THE CASE, UNPLUG THE SPEAKERS, 4SCREWS TO OPEN THE INSIDE CASE, UNPLUG THE PLUGS THAT YOU NEED TO SO YOU CAN START PULLING THE POWER SUPPLY OF THE MAIN BOARD"LABEL YOUR PLUGS & GROUNDS", REMOVE THE POWER SUPPLY AND THE 2 TOP PLATES HELD DOWN BY 6 SCREWS. YOU SHOULD NOW BE ABLE TO SEE AND ***** THE CAPASSORTERS ANY SLIGHT DOME TO THE TOP MEANS THEY ARE BAD.
must have a pretty good iron with a nice and sharp tip "i used a Weeler 60watt and it worked great".
"I had 1 cap that was bulging just i little on top so i replaced
it and that fixed it. I got the replacement cap from a local PC repair shop
they pulled it out of an old mother board and gave it to me for free.
the cap size is "1000uF 16v".
My new one is smaller around but don't worry about the shape of the new one as long as it's a
THANKS TO ALL:
Thank you to all the great posts they helped me do the repair and i think i would have bought a new 400 dollar LCD TV or paid a lot to have someone fix it if i hadn't stumbled across this forum.

I plugged in a USB cable from my Playstation 3 into the USB port on the television and into my computer and it worked! However, I have to leave it plugged in or i won't be able to turn it on once it gets shut off again.

The charger does fix the power problem. I did contact Olevia tech support after 2+ hours on the phone and they had not heard of the charger solution and did not recommend it but when the warrenty is out "what the hey". They did sell me a new power board which I installed and that fixed the problem. $50 and return the old one. Need to be familiar with computers or electronics to do yourself.

The problem with the Olevia 23" not coming on with the remote control or the front power button can be solved with a USB cable plugged into the service port on the rear of the set. That cable will have to be plugged into a USB port on a computer or better yet a low voltage USB style charger. I purchased on from Radio Shack. It seems that part of the internal TV power supply that feeds the off/on circuitry is failing and the necessary power can be delivered through the service port. Hope this helps!

Unplug tv and press on power button to power cycle

I replaced the 1000uf 16v capacitors along with the 220uf 25v ones (4 altogether) on the power board. Tv works great now. Easy to disassemble/reassemble.

I found a power supply at the following location
It's the part number on the power supply and it lists it for the Olevia TV. The price is $51.95.

I decided to give the soldering trick a go, since I have no fear to speak of when it comes to tearing electronic things apart. Plus, for me, poverty is the mother of invention. One difference I noted was that Dogset mentioned CS20, CS28 and CS22 as the caps that need changed. On mine, 20 and 22 were obviously bad (bloated tops—not flat) and in addition, CS23 was bad as well. Now, visually, CS28 looks fine on my board, but I believe I will go ahead and replace it as well, since it was mentioned as a possible culprit. As far as do-it-yourelf goes, I'd have to say this is for relatively brave folks only. However, all I needed as far as tools to get the job done was a cheap little Weller solder iron, and reading some tricks on the internet concerning how to un-solder the caps from the board. It's really not hard to do, just mildly intricate, so you do need patience and a steady hand. The trick is to heat each side and essentially "rock" the capacitors back and forth as each post's solder pool liquifies. about three or four "rocks" per side and the caps are free. Now I'm off to discover an electronics shop that will be able to sell replacement parts. I'll keep you posted, and thanks to everyone for your suggestions. Couldn't have gotten this far without this site.

Could you upgrade the ati chip? if so, what to?

Same issue, TV won't power on, the problem started about 6 months ago and was fixed using the USB cable method. BTW I called Olevia tech support, the parts dept said that they do not have any more of these power supplies and are not expecting to get any more in ever... so me may all be S.O.L. unless we solder in new capacitors ourselves...

Where is this hidden usb port?
Posted on Jul 19, 2008
I did the usb to service port with my PSP cord and it booted up fine. Its a temp fix though. How hard is it to install a new powerboard? Is it like installing a PCI card in a computer? Do I hjave to solder anything? I was ready to buy a new TV, but now I think I can fix it. Thanks everyone!!

Wow! This actually worked. I don't know what this part is but I will look for it. Great suggestions!

Mine also had the same turn on problem. Replaced the three capacitors mentioned above and it worked . . . thanks
Posted on May 15, 2008
Where can you get the capacitors from. Thanks
Posted on Apr 22, 2008
That USB to computer worked great, thanks.

Anyone have the part number of the power supply board to order from Olevia?
Posted on Apr 05, 2008
Appreciate all help. The USB port from TV- to- computer solution did not work for me. I eventually called OLEVIA at 1-866-965-3842 and bought a power supply for my 37 inch model. Again thanks. You gave a non electrical novice the confidence to try.

In regards to solution #7 through #9, how hard is it to do? Would it be recommended that a novice like me take it to a repair shop?
Posted on Jan 23, 2008
To fix this problem you need to replace two 1000uf 16v capacitors on
the power supply board, they are bad making one of the voltage from the
power supply low.
If you remove the power supply board look at the tops of the capacitors for linking and not flat on top. You can replace them for about $2.00 each. Better than $50 to replace the total power supply.

Solution #7 If you remove the power supply board look at the tops of the capacitors for linking and not flat on top. You can replace them for about $2.00 each. Better than $50 to replace the total power supply.

I had this problem with my Olevia 23". I connected a usb cable from my computer to the service port on the back of the Olevia.(USB Type A to Type B 5-pin male).

Thank you mt3355! I see this was a problem 2 years ago, this just happened to me this weekend and my set is about 5 years old. Your solution worked like a CHARM! I was like a little kid at xmas as I thought I would have to dish out more monies for a new monitor. At first I thought I didn't work until I also plugged in the AC/DC cord and BAM!, it's on, just hope it lasts!

CS22=1000@16VOLTS ALL ARE ON POWER SUPPLY BOARD
ALL ARE RATED 105 DEGREES DOGSET

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.
