If you are in Australia and have no sound on GEM and 7-Mate, follow the instructions here, to update the TV's (LG 50PB4D-AA) firmware. Once done you will receive sound on these channels.

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. http://www.retrevo.com/support/LG-50PB4D-TVs-manual/id/3068bh134/t/2/

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.

Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Search the site by type in the "brand name" to your device; [Exclude the model number], in the "Search box at the top right of the display window of the Homepage" to get gathered related posts. See the site by a desktop. Mobile view has no search box. If you are viewing it by your mobile, see it in webview.
