Question about Olevia LT32HVE 32 in. LCD Television
I just purchased this Olevia brand 32" LCD HDTV. Only 8 days using it and tonight I turn it on and there is no picture image but just sound. It is not black but it is dark blue. Called Olevia support but there was no help. They took my information and will contact me in the future. Why there isn't no picture just sound? in a brand new TV. Please give me a suggestion.
I have had the same problem with my daughters Olevia...232-S13 out of the blue ti just decides to not turn on...blue light lit where the on/off button located but no sound and no picture....i guess the saying "you get what you pay for" stands clear here.......very upsetting.....

Sorry I don't have a solution, but I've had an Olevia TV Model LT 23HVX TV less than one year. Last week, I turned it on, the sensor light is on, but no sound no picture. Unfortuantely, I purchased it from an online auction site, I recently found out the Seller was not an autorized Retailer for the TV. Syntax (the manfacturer) will not honor the warranty. So I've got a piece of junk unless anybody out there can offer a solution. I think Syntax is probably aware of a production problem, but won't admit it.

There are a few possibilities. Did the problem occur suddenly or did the image slowly darken or change color (going pink/red) before it got to this point? Do you see anything on the screen if you look very closely. Most likely it is the backlight or backlight inverter.
With a bad backlight, you'll usually see a very dim image if you look at the TV from an inch from the screen. Block the room light from overwhelming this image (sometimes a carefully positioned flashlight will help you see something). If the inverter or video board is bad, you will see nothing.
For an out-of-warranty TV, open up the back of the TV and remove the shielding. Look for any scorch marks or bulging or damaged capacitors. (Sometimes other parts will fail on this part but these can be spotted easily. Capacitors look like cylinders on a tripod.) The scorch mark and smoke may indicate a resistor or zener diode that had been used as a fuse and is now gone.
If you borrow (or have a) high-end multimeter (able to measure high frequencies - 50 kHz) or an oscilloscope, hold the multimeter probes a fraction of an inch apart about an inch above the inverter board and power up the TV. If you see a 1 or an actual value, you have a good inverter. If you see a reading near 0, the board is bad or the multimeter can't resolve the frequency.
In either case, you can buy a replacement inverter for $50-150 and just do a simple swap. Disconnect all of the wires (connections are similar to molex and ribbon cables in a computer) and remove board (a few screws usually). Connect the cables to the new inverter. (If you google backlight inverter replacement, you'll find videos and text descriptions.) Note the part number on the board, including the Rev number, and order the exact one (shopjimmy.com or lcdparts.net are good starting points). Universal inverters do exist but can result in reversed controls (up to lower the brightness). Replacing individual parts on the board is cheaper but more prone to not tracking down all of the bad parts.
If the inverter is good, then it's probably backlights themselves (several in most TVs). These are sandwiched on the perimeter of the TV (usually under some tape that holds the lamp, reflector and other parts together. You need to order by length and width and get ones for your TV size. Remove the tape, and separate the reflector (make a note of how things are put together) then you have to Dremel (or use another rotary tool) to remove the plastic to get the backlight out. (They are often molded into the frame.) Then put in the new backlight and reassemble everything. (http://www.lcdparts.net/howto/default.aspx) but for an overview: http://www.inventgeek.com/Projects/BacklightFix/overview.aspx Then push the new backlights into place, reconnect the wires and close up the sandwich of tape and other parts around the screen. Then replace it in the bezel.
With a good spare backlight, you can test an inverter for condition (plug together and turn on the tv while the box is open). Similarly a good inverter can test the backlight.
I hope this helps.
