Blurred picture, after some warm-up it back to clear picture

Sharp tv dont know the model, experienced picture outline blurred, but after about 20 minute it goes back to normal, what could be the problem of this, I suspect the screen grid of the CRT but not sure, another suspected piece is the FBT, perhaps it has a shorted coil, so as not to be able to build up voltage for the screen grid, can you help me sort out the problem?

SOURCE: blurred picture, after some warm-up it back to clear picture

If the problem doesn't return after the picture becomes normal, then it could just be due to the electron gun taking longer to fire up. I don't know how old your TV is, but TVs older than ten years typically take longer to warm up than more modern sets.

Hi Paul,
Do you get clear OSD. If yes, it is the main board, if not unfortunately it has to be the lcd panel. Good luck.

When switch on television picture blurred and image not clear. after some time around 20 minutes image starts to clear and tv plays normally, sound is ok


You have to check your capacitor may some of it have leak. May your picture tube have already a problem. Just check first the capacitor filter on the flyback that supply the power for the CRT socket of the picture tube.

I just hooked up my new Samsung 55" LED LCD TV it has 1920 X 1080 resolution and 240Hz speed. Initially the picture quality was fantastic, sharp clear great colors...almost jumped off the screen at you....


Try the Direct TV connected to the TV via component cables and see if the picture is clear and stable at the same time. If it is normal check the Samsung website for support on your model of TV to see if there are ANY known issues and or software updates. Please take a moment to rate my answer. Thanks..

Blurred picture with lot of static


This model has a chronic problem with the crt socket arcing and causing this problem. The only true fix is to replace the crt socket locate on the small bd. that plugs on the back of your picture tube. You can however have some success by locating the focus control on the flyback transformer and slighly adjusting it until the unit stops arcing. If you are not familiar with high voltage safety then please have a qualified service tech perform this repair.
