I have some problems with my Samsung 32in LCD TV, the picture will gone for a while if i turn on or off the switches on my home especially celling fan and lights. I thought it was my TV has some defect or something, but when i switch to tv mode and composite input and there is no problems but if i switch to component source the picture will keep flashing or like on and off it self and the backlight still lit but only the picture is gone for like 1-2 secs, and it back on and if you continue switch on and off the switch and picture will gone again and back on until you stop switching the switch but not all switch will cause my tv like this. please tell me what going on and is the component cable caused this or something, becasue it happen only on component source...

Did you try on HDMI ?
Does it giving the similar problem?

Im having similar Problem...

Mine only occurs if i turn on or off the water heater switch...

I think its caused by the sudden lack of power or vice versa

Dont worry about it...i think its normal

No, my dvd player don't have HDMI

I got a 29 inch jumbo tv also have the same problem, I asked Panasonic they said the tube inside got problem and this cost around RM600 to fix it... Then, I bought a 37 inch Panasonic LCD tv, the old tv i put aside (sometimes i on also same prob)... But LCD tv no tube inside so i dunno what happened...

Change another cable and try the video output did you?

Try to use a power stabilizer/conditioner?

Probably your main electric board screwed bro, better check..

agree, I think is better use power stabilizer cos ur house electric current not stable,
it may cause ur LCD burn if more serious..

If you're experiencing blackout/trip suddenly, most probably something is wrong with your wiring. If not then power stabilizer is the way to go.

maybe, your TV power socket is sharing same circuit with the other devices which are not grounded properly

may be ur house at maximum load. it senstive to electrical spike

TS mention problem only with component input on the TV itself. Composite still ok.. So, the problem could be something else...

I try already other component video, from computer video card @ 1080i and 720p and the picture flashing is gone when i open and close the switch in my house.
Now i put back to my dvd component video and its flashing on and off when i flip the switch on my home!! and it's including my rmvb player! =(, now even more switch infected too like few table fan and my amp but on off from the amp swtich not the main plug. what the hell has happen eh?

Try to plug in to another power plug point. And use the Comp cable try switching on again?
I suspect cable issue but its from CPU GPU output.

Must get some sifu advise leh..will get back to you

I already try it, the wire man come few days ago and he has make another plug and a new set of wire including earth wire directly from fuse box and also using difference fuse on the main box too. its still flashing like the hell when i flip the switches including amp switch, it only happen with the dvd player and rmvb player but if i connect component video through graphics card its ok no more flashing.
