The first thing to look for with symptoms like this one is loose conections,in your case you might want to tap on the set while is working to see if you make it go off, if the picture distorts in any way ,if you are familiar with tv service you can remove the back cover and try it,tap lightly in different areas to see if it reacts differently,the set needs to be on while you try this and someone else need to look at the picture while you are doing it.You can use a wooden or rubber handle escrewdriver,it should not take much to make it act up.If you are not too familiar with tv service be safe and call for assistance from a servicer,you will need to resolder the loose conection if you find them,be attentive were you tap it so when it reacts you can flip the board and check the area you were taping on.Let us know how it goes or if you need more information.

My Emerson flat screen wont turn on. The standby light is on and when you turn it on the green light blinks about 6 times goes solid for a second then straight to standby again. Every 20 times or so you...

The 6 blinks are actually a error code. Go to the Emerson web site you should be able to look the code up there. Its more than likely a bad power supply. I have a friend who works on tvs and he said nine times out of ten there are popped or raised capacitors in the power supply. Hope this helps.

LG 42 Plasma try's to turn on but just goes back into "stanby" ?

Check to see if you get Va and Vs voltages from the power supply. There should be some wires running to the y-sus. A couple of those wires will be labeled va and vs. Are they present? There will be a sticker stuck to the panel somewhere telling you what they should be.

When i switch tv on, it shows picture for 5 seconds then goes into standby. the tv is a vistron ltm-3271e lcd

The problem is associated with the power supply that cannot run under load. The showing of picture for a brief period of time indicates that the main board, ballast, inverter and panel drive are all OK. The unit turns on but the power supply cannot sustain the power requirement of the unit and shuts down.
The usual culprit on the power supply are blown or bad capacitors. Check the power supply for such capacitors. If no apparent damage or defect is found, replace the power supply.

SCH-I760 wont go into standby mode

Check your Power Management settings.....
Start> Settings> System (Bottom Tabs) >Power (Icon)> Advanced (Bottom Tabs). Make sure "On Battery Power" is checked and select a time 1-5 minutes.

If your on the phone for long periods you may want to check the "Power Save" tab also. It's to the right of the advanced tab.

Problem with system

I have two of these units and have identical problems. Noticed that the cooling fans do not come on so suspect the amplifer is overheating and there may be a thermal sensor that shuts the unit down.
