Ours used to do that - and then we moved it to another state with us. Since the move it doesn't shut itself off anymore. I suspect that the problem was dirt and dust inside which got knocked loose in the move and the shutdown was due to thermal limits being exceeded. You may want to try vacuuming or blowing out the dust inside if you feel comfortable opening up the unit.
could be that either the dvd or the vcr are malfunctioning, usually it is the vcr that creates the problem. If you turn tv on and set vol to low see if you can hear the noise of the motor loading or trying to load,with out a tape inside. It may be a good idea to have a qualified tech repair it, these units are difficult to work on and further problems may come up if you are not familiar with the tv.
how old is your tv?? ours was 2 1/2 yrs old it was a 40in lg hd ready lcd tv it just crackled and turned off one night same as yours it would turn on but with no picture or sound....we took it for repair and they said it was something inside that is basically impossible to fix...it would have cost more that the tv itself. BUT trading standards say a brand new tv should last upto 3yrs...you need to get a free qoute nd if they cant fix it contact trading standards and the tv MANUFACTURER not the shop where you got it....you NEED a reciept to do this for proof of when you purchased it...hope this helps :0)
The tube is the most dangerous part. It contains a vacuum and also a very large charge. The easiest way to make it safe is to unplug the end by removing the pc board attached to the back. Once removed, you will notice a large round plastic "pin" that is keyed. With a pair of pliers, squeeze the end of that part. This will break the end of the tube and allow air to enter. Do this carefully and only break the very end of this glass part (indide the plastic). You will hear the air enter the tube. This will effectively remove the charge at the same time.
most likely cause is a dirty mode switch,the contacts inside it oxidise with age.cleaning or replacing is for a tech only really,as the vast majority of these units are a nightmare to work on.problem usually starts off intermittent,with random tape chewing,etc.hope this helps somewhat.....steve
There might be a failure on the power supply or horizontal section of the TV even if you see some light inside the TV. Some of the voltages could be missing and that is why the TV fails to power up.
If you know how to use a multimeter, you could check all the fuses from your power supply.
Unplug your TV from the main AC line if you intend to do it yourself.
You will know how much you can do or it might safer to contact a tech.
Let me know if you need further assistance
Sounds like the colorwheel (used in DLP projection sets with a single DLP panel) is going bad, either the wheel itself or the bearings on the motor driving the wheel are starting to fail. I would recommend getting a professional to service the TV set.
