    Magnetic interference from unshield equipment OR Hi-fi speakers placed too near the TV set. Turn the TV set off for about 30 minutes and turn it on again. But you have to move away the speakers from the tvset, and in any window airconditioner is close by then you need to change the direction of the tvset.

    ***open the menu of the tv and reset the setting back to factory settings. this will definately work***

My Samsung HLN4365 tv made a loud popping noise then the picture went to black and white with a lot of interference in the screen. Also now makes a loud humming noise sometimes


You are likely to have developed a bad color wheel. Do a search on Ebay with your model number or Google the model number. This will give you a heads up if you get a TV tech to fix the set

Sony KF50WE610 Vertical Blue Lines Across Screen


the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.
good luck!

New (12/2007) 1080p Samsung 46" LCD TV. Flickering white horizontal lines on entire left screen. Double picture. What's up?


At this point there is not much you can do.
If this LCD is less then a year old, I would suggest to contact the manufacturers to get it fix under their warranty.
Good Luck.

Projection Tv Problem


The problem you are seeing is a convergence problem. This is a common problem and is fixed either by resoldering bad connections on the convergence ICs or replacing the ICs. These are large black ICs attached to a heatsink and are marked STKxxx. Try resoldering the pins on these ICs first.

Horizontal lines in picture


That's almost always due to RF interference from an electric motor. It doesn't even have to be close to your TV, just operating on the same circuit or near a poorly insulated wire, which acts as an antenna, injecting 60Hz (and harmonic) noise into the power supply.

If it's right next to the TV it will be even more pronouced because the RF interference resonates into the TV circuitry itself, not just the power supply to the TV.

Typically a high current AC motor like a vacuum cleaner, refrigerator, dehumidifier, air conditioner, furnace, etc.
