I had the same issue occur on my ln55c650 (screen flickering, not the actual image but the front lights flashed which was too distracting) and they had to replace the power supply pc-board. Seems some issue with power module in the TV rather than the side panels. Luckily for me, TV was still in warranty.

Video turn off and audio works fine


There could be several things going on. I would seriously recommend you get a diagnoses on the set. But the first thing I would do is when the video goes away, dim the lights in the room and shine a bright light on the panel. If you see a faint image on the screen, you have a back light circuit fault. If you see nothing while shining the light on the panel, you have a fault in your video circuit which could be due to overheating on main board or t-con. Again with so many possibilities at hand, I would get a professional diagnoses.

My Casio goes through batteries too fast.


you can do a few things like turn the brightness down on the LCD screen, and only use the flash when you need it! even set it to auto power off after 2 minutes. these will help significantly with battery life!

I turn on tv shuts off after 30-45min. red lite goes dim


It's likely that the TV will require service since your troubleshooting steps didn't resolve the problem. If your TV is smaller than 30", you may carry it in to the retailer of purchase for repairs. Otherwise, service for your TV can be obtained by calling 1-888-237-8289 in the U.S. or 1-866-237-8289 in Canada.

Car sat for six months. Battery went dead and replaced with new one. Got it started after new battery, now it won't start, the alarm led is either flashing bright or very dim flashing fast. I'm sure that...


When alarm goes off,put key in ignition and turn,the alarm should go off and alarm should be reset.Or,remove positive battery cable,wait 10 minutes,reconnect,when you open door,alarm will sound,insert key in ignition and turn key and alarm should go off and alarm should be reset.

Power Brightness dims after using Kinoma Player


Ok i think i can help,

Step 1: Go to preferences
Step 2: Go to power
Step 3: Change the Auto-off after: feature and increase it to 3 minutes, the maximum.

I know this will only help it a lil from the 1 minute you had before, but if you pres the volume button or something within the 3 minutes it will restart the 3 minutes.

Screen goes black


I recently had a similar problem with a MAG LCD monitor. Try the following to see if this resolves your problem: - set brightness to a lower level. On LCD monitors you can go as low as 0 and still see the screen. With my problem when I set the brightness below 70% the problem went away. A few days later I turned it all the way up to 100% and the problem did not return. However I did not continue to keep it at that level. I found no need for it and find 50% to be exceptable for my needs. I would say yes it does have something to do with the lamp controler which controls the lamp brightness. I do not know all the technical reasons why a controler starts to have this sort of problem. If your monitor is still under warranty I would take advantage of the free repair otherwise keep the brightness below the level that causes the problem; for me that was under 70 percent. I hope this solution works for you. Perhaps there are others that can give you all the technical reasons why a controler starts to exhibit this behavior. Sincerely, Dean Kenneth Robinson
