The microprocessor IC is hanging up possible due to some errors in the system.
Power off the set and tighten all connectors in the main mP board. make sure that the mP and the allied circuits are not having any dry soldering. if suspicious then solder the crstal and allied circuits and the mP pins.
Check if there is any data that is making the mP hang up. check if there is heat build up onthe mp , if so make if cool instantly using a freeze - it spray, if the fault changes thenit can be the mp IC.
If not check for the similar feedback from the other sections.
Use only on the component and not on the printed board.

TV going a little crazy


I would suggest you contact LG even if the set is out of warranty there may be a software upgrade for this kind of issue or they may be by model number familiar with the problem.

It is what I call a micro related problem-all sets have a micro processor and when you unplug the set it resets this circuit.

Every time I turn my LG television to the TNT channel while the NBA is on, it immediately turns the TV off, and then it comes back on, the off and so on until I turn the channel. This only happens with...

It sounds like a control board issue that is not an easy user fix. I just did a web search to see if anyone had the same Problem with no success.

Frozen picture on LG LCD 37"


Try One of your working TVS and connect it to your cable outlet of the TV that is having problems. If that TV Does not work then there may be a degraded fitting or the Leg coming of the splitter to that outlet could have a Low Signal Problem
Next Take the First TV that was not working properly and put it on the cable outlet of one of the TVs that is working properly and if the TV set works on that Channel then you know it is not your TV that it must be the cable

LG 42LC7D TV does not want to chg channels after 5 min of use


There are some inductors that are out of spec. LG's original SB said to replace some of these with a jumper, but it only lasted a couple months.

You need to have the Total Main Assy replaced.

Send it back ASAP and get a replacement! I'm serious. You wouldn't want to baby sit this lemon by missing work because you're waiting for a home service tech provided by the company. When the tech comes, he will not have the part required to fix the unit and you'll be waiting at least a week to get another service call. That's another day missing work. You are one lucky guy if the servicer can totally fix the unit to your satisfaction in two visits. Days missed at work could very well add up into buying a new TV. Do not take ownership of this problematic unit especially if you just bought it. Send it back!
