LG 42LB5DF turns on by itself and the channels keep changing

I bought this tv second hand and all has been well but I got home the other day and the tv was on. I started watching it and now the channels keep going up in numbers. Its not the remote or the buttons on the side of the tv. All presses in and out with no problems. Can you plase let me know what to do and what part I might need to order to repair it. Thanks! If I unplug it for a little while it will work with no problems for a little bit. Not sure what the cost would be to repair it.

    my tv keeps clicking on and off by itself

  • Anonymous Jun 18, 2008

    I've had my LG 42" flat panel for about six months. The channel won't stop changing. I've checked the panel buttons and the remote, also unplugged the TV, and nothing will make it stop. I guess I'll try to return it to Best Buy....certainly not happy I spent $800+ for a TV that only worked for six months.

    MY TV WAS WORKING FINE UNTILL EVERYTHING WENT BLACK THEN JUST KEEPS CLICKING ON/OFF HOW CAN I GET THIS SORTED???

  • Anonymous Mar 31, 2009

    I have the same issues. Now the sound is gone. All this started with the FIRST model that I bought. This one was brand new out of the box and it took only 3 months for the problems to start. I have filed a claim With LG to replace the TV under MAN. WARNT., and they are trying to replace it with a TV that is A Base model HDTV. You are gonig to have to fight to get these issues resolved. If you have issues with your LG 42LB5D or any LG product for that matter, the man to contact @ LG reguarding this, is Charles and his DIRECT number is 256-774-4187.

    He would love to hear form you!

The tv eprom has been corrupted

BUT you need specialist equipment to re programme the eprom.
also if you intend to try this yourself you will need a copy of the un-corrupted info for th eprom

Programming wrking fine, however i have no channel guide/listings


Call LG. They will have you go through diagnostics over the phone and ask for diagnostic data the TV has in memory.

I have done this about 10 times and my TV usually loses all it's TV guide data after I customize my channel listings (delete all the channels I don't susbscribe to). Within a day or two of calling them, my TV Guide is back to normal.

I will never buy another LG TV. Thank God I bought the extended warranty. I've had the power supply already replaced (this is also the 2nd set..replaced 1st set due to same issue), TV turns itself on at times ( in winter - low humidity/static electricity??), and loses TV Guide listings on a frequent basis (after I change the channel map).

TV Changing Channels on It's Own


Are you changing channels with the remote? Try taking the battery out of the remote, its buttons might just be getting stuck? If, when changing the channel by hand, it persists, then it is an electrical problem, and you should contact LG to see about getting your unit replaced.

LG 42PX5D 42 in. HDTV Plasma


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!

42 in LG LCD TV turns off by itself


Found that TV started switching off by itself. Would try to come on..green light blinked for 2-3 seconds, tv came on (with picture and sound) for 1 or 2 seconds and then it would turn itself off. Found that the issue is with one channel only. If you are facing this issue....try quickly changing the channel the moment it comes on. You can do it either with remote or with the TV buttons directly. also in the same logic, if this is still happening, try changing the source to another (rgb-pc, av1, av2 etc). Basically change it from whatever input it is on currently, if changing the channels does not work. My symptom was that the tv made a loud 'TIK' 'TAK' sound which is louder than normal.
