Question about LG 42LC2D 42 in. LCD HDTV
After TV cools off it comes back on, until it shuts off again.
top link, is your user manual, below that is a service manual, this is what the engineers use to troubleshoot and repair these units. This symptom, is being caused by something causing an Overload, possibly thermal, and this component(s) is causing too much current to flow in that part of the circuit, this is "Sensed" by the Power Supply & Computer, and then, the PSU is commanded to shut down, to avoid a fire, and explosion, or both. After which, the affected part, cools down, and the set no longer senses any fault, and allows it to work again... until...... If you cannot fix it yourself, then it is nearly always my professional opinion that one should always get a "Quote" from the manufacturers recommended service center, LG, in your case, please contact a local or head office and ask for a referral to an Authorised service center. I cannot stress how important that last point is. It is even worth the cost of shipping. You see an authorised service agent, will have trained staff, trained on their brand, also they have first hand access to parts, original parts. This will actually save you money and ensure you can actually get it back fixed. Of course asking for a "Quote" also gives on the option of repair or replace. Often my clients,do not go through with repair, unless it is moderate, but in some of the more costly jobs they see it, as do i, that a replacement, with a warranty, is a better option. As an aside here, one could then tear the TV down, and sell the Known Good bits. You'd be surprised who needs parts, I myself often must by from third party sources to effect a repair. So money could be recouped, somewhat,and help out someone else.

Hello Kim, hi, This type of problem is a nightmare to service, this intermittent problem is caused by overheating, and could be a power supply problem. there is a need to replace parts on the power supply board with heatsinks. after replacement, we test again. Or a simple silicon grease on all parts with heat sink is required. call for service if you cant figure out what im saying, thats it, keep me posted = )
