Top 20 LG 37LG30 37 in. LCD HDTV - Page 9 Questions & Answers


This may not be a problem. I believe there is an audio effect used by video production houses to 'boost' the presence of an ads audio and this effect is not picked up by the electronic device's (in this case TV) volume stabilizing software. It is intentional by the makers of the ads.
A work-around could be to try different configurations on your TV's audio settings, such as just mono, or just 2channel stereo, or surround sound - on or off, increasing/decreasing bass and treble levels in different combinations.
The down-side to this is to get a comfortable, uniform level of volume across the board, you maybe sacrificing some sound quality - but, as with our eyes, our ears adjust well quickly (hence don't listen to too loud sounds) and what you may not like now, will sound ok tomorrow.
I can't tell if there is a fault or not, but this may help if you "trial" some options.

I would advise you to call LG's customer service at 800-243-0000 to set up service. There is a service bulletin about this issue specifically for your model. Your set requires a simple software update to fix the audio delay with HDMI issue. You can ask LG's customer service to refer to bulletin #0IVL20080379. Hope this helps.

Depending on your cable provider, some of the HD channels may be present. If so, these are ususally located in the upper channel numbers. It sounds like you are receiving some of the HD lineup. A cable box will probably allow you to view more HD channels including the premium HD channels if you subscribe to them. You should not be noticing a delay with the HD channels only. If this is what you are experiencing without a cable box, then it would be an issue with the HD tuner built into your TV set. LG customer service can let you know if there are any software updates available for yourmodel that can resolve this. Additionally, if you are getting your sound from an Home Theater system then you will notice an echo if using the TV's built in speakers at the same time. This is sometimes mistaken as an audio delay. If you are using a home theater system, be sure to disable the speakers that are built into your system.

check power at the socket, if there is take it to an engineer. Don't try and fix it yourself. This page if full of tales of people who change boards and never end up with a working set. The course is 2 years, the test equipment costs thousands.

It was thrown out for a reason, and probably because it is uneconomical to repair. Take to a repairer for a quotation to fix it.

This explains why, and why you can't diagnose television problems on an online forum. The television sections are really only for help with manuals and remote codes.

Here are similar questions that we see often.
Question:

I've replaced everything in my television because it previously had a black screen with no lighting. Now it doesn't turn on at all and all I have is audio. What could be the cause ? Or

Turns on and sound works fine, but the picture is distorted (solarized? polarized? not sure what the term is) I replaced the main board, but that didn't fix it.
Or

I have an LG 55LM6200-UE with a dim lower-left. I just replaced both LED strips with no resolution. There is no physical obstruction visible, so this has to be a cable or board problem, right?

So your television stops working properly and you think it must be easy to fix, because you can buy boards on eBay, and you can watch YouTube videos. So you make a decision, you buy a board and you fit it, but the television still doesn't work as it should! This is a classic case of the 'let's try replacing this' method of television repair and illustrates why it is a bad idea. It doesn't work for a number of reasons. To correctly diagnose issues, you need to know every board, what it does and every component on the board. You need to know which part has failed, replace the component, or replace the board. The parts you purchased off eBay were probably out of scrapped sets and not tested. The part you put in was dead when you put it in, so you just moved on to another guess at what might be the cause and replace a board that is fine. And so it goes on, you change all the boards and it still doesn't work. Did you notice the large print that says 'NO Refunds, NO Returns'. This is to stop you sending your old one back and saying it didn't work, but the unscrupulous sellers use it as an excuse to get money for selling items that may, or may not work! The course to be a television engineer is 2 years full time education, take it to someone that knows how to diagnose and fix. It is by far the cheapest option. The part that failed might be a 20 cents fuse diode hard soldered to a board. They will charge you $5 in parts and a couple of hours labour. It's not the fix you want to hear, but it is the best advice.

Probably faulty Y drive board. Take some measurements and see which board has the short circuit transistors.

If you power on your TV but you do not see the menu options, or any video display - just a black, blank screen, and possibly no audio as well; try the recommended steps below to resolve the issue. Check if the status LED, in front of your TV is ON. ... To confirm, point the TCL remote towards the TV and press any button.

take it in for professional repair, it is by far the cheapest option than swapping out boards that may or may not be faulty. You need all the test equipment and the knowledge.
