Check and replace its tuner. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ Search the site by type in the "brand name" of your device, in the "Search box at the top right of the Homepage" to get gathered related posts.

Lg tv says no signal


1) check the cabling with a tester to ensure both ends works at connected.
2) check the tv signal out from the wall mount outlet with a tester to ensure tv signalling is at acceptable level of strength;
3) if both works, then direct connect the TV to the wallmount tv signal outlet. If still not working, then ask the technicans to come in for fixing.

Screen has gone white


Only two things, a fault with the signal coming in or a fault in the TV itself. Check your cables, particularly scart leads are prone to being damaged. If the cable is ok or there is no signal on ANY of the input signals (tuner, dvd etc) then the TV is likely faulty.

I got an American model of LG. i can not tune it by auto nor manual can you please help


You can get a manual here: http://www.lg.com/us/tv-audio-video/televisions/LG-lcd-tv-32LG30.jsp . Click on the Support and then on the right hand side look for User's Manuals. Since the TV has a tuner for ATSC, NTSC, and Clear-QAM, the next question is what is your signal source? (analog, digital and unscrambled cable)

If you are using OTA, make sure that the input is set to Antenna. Use antennaweb.org or tvfool.com to check the direction to point your antenna and the appropriate antenna for your distance to the transmitter. antennaweb assumes an external antenna and is very conservative in the list of channels you should be able to receive. tvfool gives the stations available with different antennas. If you have several tvs connected to one source, you may need an amplifier in addition to the splitter. This also can help marginal signals come in since digital is either enough for the tuner to resolve or no signal. (Check splitters and amplifiers if you suddenly can't get a signal that you used to receive. Also check if the antenna has been turned.)

Menu > Channel > Auto Tuning or Manual Tuning. If Lock System is active, you will need the password. Auto Tuning only searches for digital or cable channels. The manual tuning option should provide the signal strength as well for digital stations (as well as letting you search for analog signals or all signals (digital, analog, cable).

Use the input Cable for coax cable connections. Other inputs will not allow you to search for channels since they are meant to be controlled by the set-top box feeding the system.

I hope this helps.

My lg tv (had since Nov) says no signal for the tv or dvd player. How do I fix this?


Try unplugging all inputs and the power cord from the TV for 5 minutes. This will allow the main board to reset.
Next, just plug in the power plug to the TV, power up the TV, and even though there is not a source connected to the TV, check at least three inputs and see what the TV will report on the screen for each input.
Next, turn off the TV, plug in all known working devices (Cable/Antenna, DVD, Blu-Ray, Cable/Satellite box, Game, ….) with a known working cables to the TV, make sure all the devices connected to the TV are powered up and on, and now power on the TV.
Now check to see if the TV is seeing valid signal for all the inputs connected to the TV.
If your TV cannot see any signal at any of its inputs (HDMI1, HMDI2, HDMI3, AVI1, AVI2, Component1, ……), then the main board has failed and need to be replaced.
Good Luck.

My vizio tv has a ticking noise


Unless you are getting your input signal from an antenna (in or outside) it isn't likely being disturbed by radiating sources such as blinking lights, kitchen mixers, etc.
The shielding on any cable or satellite system keeps such airborne interference from invading your receiver. You might just check to see if signal cables are well-attached; not with a wrench but a firm twist or those that just plug in should be pulled and reinserted in case a shield is not contacting well.

I have an LG LCD TV (LG 37LG5000 37IN). I also have an older DVD Home Theatre System (SONY DAV-DZ100). It seems that the surround system works well with DVDs but I cannot get the sound to work with DIGITAL...


It works fine if you plug the surround system SCART lead into the AV2 input. I believe this is a 'smart' scart plug (same as SONY but it is not mentioned as in the literature). The AV1 is only good for inputs NOT outputs as well.
