SOURCE: LG 37LG30 HDMI no sound problem

This is more probably a software fault within the TV. They need instructions for HDMI inputs & a no sound is a related fault. I would get in touch with your dealer to arrange the TV to be updated to cure this problem. Hope this helps.

SOURCE: No picture on Memorex MLTD3222 flat panel LCD.

I recently got this tv from somone because of this exact problem. I have found a solution that works for mine. You can check to see if it works for you also. What I did was take of the back cover. 3 screws (1 big one in the center and 2 little ones below it). Next look at the power board. If plugged in and turned on the red light on the power board should be lit up. If so your power board is fine. Next find the component that has 4 switches. I manually turned these on and turned the tv on and it worked! Has been working ever since!

SOURCE: LD4088 LCD will not play sound via HDMI cables.

This is how AUDIO works in HDMI setup, you can select the source to send the digital audio along with the digital video through HDMI, the receiving end HDMI sound setup must be set to receive the digital audio through HDMI. Otherwise the audio may be sent and received through analog audio ports (Red (Right channel) and White (Left channel) RCA jacks) in stead. Most of the new TV and DVD player use auto detection.
So please check the HDMI audio setup to see how the audio signals are set to be processed.

Please leave rating if it helps.

Sounds like the problem could be in the power supply of the TV. Have a technican check for defective capacitors if you're not equipped to do the job yourself.

Run DVD through tuner


ok a bit confused, Tuner ? like amplifier or Tv Tuner ? regardless seems like a easy fix .

First your cable box as 3 cables:1st . Power cable to outlet
2nd. From the wall ( usually a Coaxial cable coming from outside box ) into cable box.3rd. HDMI or Second coaxial cable ( One of these usually goes to the back or side of your Tv depending where inputs are located.)
Now Dvd has 2 cables 1st to Power2nd. To TV ( Hdmi or Coaxial )
On the back of your Tv will have 2-3 HDMI inputs . Assign 1HDMI jack to each media your trying to use.In this case TV HDMI 1, HDMI 2 DVD.
Assigning HDMI's will now reflect on your TV menu selection. Choosing HDMi 1 or HDMI2 from Tv menu will allow you use or view desired Media option in this case DVD or TV.
Now if there is Amplifier / Tuner involved like to connect surround sound to, connection may be a bit trickier however same principal.Plug all media into HDMI 1, HDMI 2, respectively,this time to the back of the tuner NOT to back of TV.Once you have done that You will need a third HDMI cable now from the back of the Tuner ( output Jack, usually has lighter color markings indicating Output HDMI) to your HDMI 1 jack in the back of your TV. Now you have bridge TV/ Cable , DVD into Receiver / Tuner and Selecting media will now be done not through TV Menu as before but through Tuner / Receiver menu or selection.
Good luck .

Good Luck

Problem for Sylvania LC195SLX LCD TV Channels will not program in tv.check with different tv it works


It looks like your TV doesn't have a digital tuner in it. Without that you won't be able to receive any broadcast television stations. The spec sheet is here: LC195SLX the tuner is listed as just ATSC/NTSC - not digital. You will need a cable or satellite box to receive stations.

Cabling -- Panasonic LCD TV into LG DVD player (model no. DV6812P)


Take the basic Red, White, Yellow component cable -- plug it into the backside of the DVD player and plug the other side into the back of the t.v. Make sure to plug the right colors into the right sockets. If there are no available AV inputs on the back of the t.v, plug the other end into your cable box (if you have one).
