I had the same problem with my sis tv. You have to open the front grill and see if the filament on the neck of the crts is lit. If it not you may want to check the horizontal ouput transistor(Q416- for open or short) and its related components around it. If it lit you may want to replace the vertical output IC,Q301 and check the related components around it.
The horizontal and vertical output is on the deflection board where the flyback transformer.. you need to open the back of tv and take the board out to check...

I can hear sounds but no photo on my 19in vizio lcd tv but the scrteen it only stays on for 2-3 seconds but the sound stayes on as long as you want


Take a bright flashlight and place it on the screen. Around the edged of the flashlight see if you can see an image moving around on a good channel. If so you need an inverter/lamp repair/replacement.

Make sure the cable is on when you autoscan. If the autoscan doesn't see it,manually inputing won't get you there. Make sure you have the correct band selected when you autoscan.

Olevia LT27HVX 27 just blue screen


I just had this same problem over the weekend. Is your TV hooked up via HDMI?? Mine was and i've been having problems with the tv image shrinking whenever i turn on the tv, so i would have to change the channel 1 or 2 times for the image to come up normally. On Saturday I went to change the channel and then all of a sudden I hearld this loud pop and when the image came on it was just a sky blue screen, I couldnt see anything, but I could hear the channel. So I disconnected the HDMI and hooked up the tv with component cables I had and now it works fine. I ordered a new HDMI cable just to see if it will work again. If not, i'm calling Olevia.

Problem with sound


Its easy. Jus from task bar click on that Speaker Icon of sound. In that you can select the left channel, right channel or both! Keep the pointer in middle and you will get sound in both the channels! Enjoy

Only left/right have sound during the test


all of the channel are resonding to the test. but you cant notice it bec 5.1 speakers, each channel are designed to respond to a certain frequecies.  the L/R channel your talking about have the mid-range frequecies so it responds clearly compared to other channels...

 

hope that helps...
