yes it is, and yes it can. BUT it maybe a difficult problem to determine if it is intermittent, you will be best served waiting until it fails "Hard On" otherwise it may take some time to find the intermittent fault.

Off-Air reception (Antenna) of TV Guide comes from a supplier called Rovi (formally known as Macrovision, Gemstar). They have supplied your local CBS affiliate with a TV Guide application known as SCTE 127 or VBI in MPEG. Follow these steps until you have found a solution to the TV Guide - No Information Available.

1. Check to see if your local CBS station is coming in clearly not tiling.

2. Reset your TV Guide through your TV Guide Menu, for more information copy and paste the link below. (What usually works for me is setting up the guide by putting in 99999 for the zip code then answer all other questions. After it says your TV will receive the guide in 24 hours then setup the guide as you normally would with your zip code).

3. Contact your local CBS affiliate engineer and see if they are having problems with the TV Guide transport stream i.e. SCTE 127 or VBI in MPEG

FYI if you get your service from a Cable TV company they will have to pass this information through their system commonly referred to as Passing PIDS.

Since the set is less than 1 year old, it should still be under warranty. Request warranty service.

The noise you are hearing is probably arcing inside the set on the power supply board. Continuing to attempt to turn on the set will only make things worse. Please request warranty service as this is unusual for a TV that new.

I believe its asking you to pair the TV's wireless remote. Follow mfgs instructions for pairing remote.

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.

Check the output voltage from its SMPS power supply. You should have some experience in service work to proceed. It it seems OK, then check the main board [horizontal output section circuit] and pin-cushion circuit for defective component/s. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience.

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.

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.

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.
