I have an Olivia 747i. The tv turns on and only the Olivia screen is displayed?

Check whether all the input devices have been connected to the TV properly and the correct input such as AV-1, 2, 3 etc. are selected as per your input connections. Check whether the input device is on. Look through menu in remote and just recheck the settings and if necessary change it to factory defaults.

Have power and sound, but no picture. Syntax Olevia LT30HV 30

Common problem unfortunately. That's you need a new inverter board. You can have it repaired or if you are savvy enough you can replace the inverter yourself. The inverter board costs about $150 at
Good luck!

Help putting it back together

Dragon22 -
I'm working on posting a procedure/solution somewhere where all of the photos can be posted. May wind up on Flickr to get all of the pictures loaded on there. What state is it in? If you have the power distribution box, motherboard, and CCFL inverter removed, and are staring at the back of the box.

If you have all of the screws and components, I will help you walk through it.

Black Box

It sounds like the "Text" mode of closed captioning has been turned on. If you look towards the top-right of your remote you should see the "CC" button. Push that and set the option to "Off"

Not really. Repairs are right about $150 - $250. Resistor Kit, Caps., maybe other parts, and labor charges.
