Power Issues for Olevia LT23 :(

My Olevia LT23 is having a power issue. Power supply is present as the red standby light is on but i just coudn't turn it on by pressing either the remote button or the manual button. When pressed the light goes out for an instant than right back on without the screen coming on.

I have plugged my cell phone USB cable into the service port (as suggested on this website), which so far, turns the TV right on but it will not turn back on without the USB plugged in.

Any suggestions for a permanent fix?

    Our Olevia works fine for about an hour then switches itself off.

    We have tried everything from new cable connection to power source in home.

    I have tried the "support" line 3 times now with no resolution with this issue.

    They have suggested that I download their firmware onto the TV with an extra cost to me for a flash drive and usb-a cord and this may not even rectify the problem it may add to it!

    The power just turns off . After trying to re-start the set the blue (power button) will Blink and continue to blink until I turn off the master switch in the back and unplug the power cord from the tv. Could it be overheating?

    I do smell an electric hot smell from the set itself.

Olevia 537 keeps turning off


I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.4_23_2012_5_08_51_pm.jpg

My olevia 42in not getting power is it the power supply thats going out sometime it turns on


Look at the power supply first; look for burnt parts, bad capacitors, etc. Look for 5vdc, 12vdc, and 24dvc.

My Olevia 27in. LCD Television does not turn on


Well, at least the standby 5vdc circuit is still working but the problem can be in the controller board is not sending the signal to turn on the main power supply sections, or the power supply itself is bad. Look at the power supply first for burnt parts, bad capacitors.

Olevia 42 inch Flat Panel has power supply issue... Blue light does not come on and tv does not turn on... I have tried all different things to get tv to work with no positive results


What did you try so far? The main power supply MUST have at least the 5V standby supply section working. This 5v is used by the main control board to send out the command to turn on the main power supply section which will power up the rest of the TV circuits when the power switch is activated either by the power button of remote or on the TV powern button. Look for this 5v first.

I have 19" Olevia LCD TV and the red power light comes on when you plugged it in but the TV DOES NOT power on


You only have 5v standby voltage circuit working. The problem can be i nte main power supply or the main control board that send the signal to the main power supply to turn on. Those are the two place to look for.

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.

Power issue with Olevia LT23


I think this model has a timer on it, it seems to go when the warranty runs out, not proven but Mine went out about a month ago. My only fix is to plug my tv (via the service port which is COVERED) to the usb port on my computer using my BlackBerry usb cable, in other words the Mini USB. Seemingly I must be logged on to do so and wait for the Chime form my pc, a balloon will pop up for new hardware not recognized (vista) then press the power button and then it turns on, unplug the usb cable and make sure the source is set to tv / video or else it will power back off and you will have to start all over. Theres NOT A PERMANENT fix yet but this is what I do every time I want to use the TV, I have a laptop so I use it as the Monitor just to watch movies. If you have a desktop I recommend keeping the cable handy BUT DO NOT LEAVE THE USB CABLE IN FOR LONG USES. THE SERVICE PORT IS COVERED FOR A REASON!!!

Olevia LT23 23in. LCD/TV


I had the same prob, but found out that the problem with the Olevia lcd tv's on most models not powering up is because of failure of capacitors on the power supply board that I do believe is due to excessive heat and lack of ventilation.

I took the tv apart and got access to the main board and just by looking at the capacitors I could tell which one were the bad ones..

I will show some pics that I borrowed during my repair, hope it helps as reference as it did to me.

I replaced the bad caps with new ones that I bought at a computer parts store.

Now I got my lcd tv back ON but this time I added a internal cooling fan for better air flow that will reduce this malfunction from happening again.

Hope this helps.
