The adapter is USB on one side, and the real little connector that is on the other end, used on Sony Camera upload cables and such. Looks like a mini VGA connector, without pins in it.

I am now using the Olevia as my computer monitor, to see how long it will go for.

Once the monitor was up and running, the cable/adapter was not needed.

I think this is a lesson to put all your tvs and monitors on UPS with AVR tehcnology. The spikes that come through telecom and cable companies can fry components.

Will order the diodes and do the self-fix at some point.

Only problem now, monitor base has no TILT capability..... Setting without angle is weird

Red lite comes on but tv will not power up.


Follow the solution for service port 'jump start' with a usb plug. Plug your cell phone charger in next to the TV. Touch the metal prongs of the service port with the metal part of the usb until you get a brief 'flash' on the TV. Then turn on the tv set. It takes patience and a flash light to do this, so you can see what your touching, as my husband couldn't get it to work, but I could.

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!

My service port looks like an 8-pin mini din mouse port


If you are just trying to 'jump start' the tv to turn it on, get a usb cable, like the one you use to charge your cell phone. Touch the metal part of the service port, the 8-pin mini din witht he end of your charger cable that is plugged into the wall, until you see a flash on the screen, then turn the tv on like you normally would. It should turn on. If it doesn't jump it again.

My olevia LT23HVX does not power on


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.
