Question about Samsung 32 in. LCD Monitor TV

Open Question

One second loss of sound when fluorescent light switched off

Yesterday I purchased a Samsung 32"series 6 4HDTV. Every time I switch a fluoresent light eg kitchen 20 W fluoro, the TV loses sound for about 1 second. Sometimes the image momentalrily showls blocks of colours about 1 cm square randomly dispayed on the screen but in a string or bunched together. This happens even if I connect the TV by a long extension to to the most distant socket in the house. I have checked voltage and power factor of the supply and both seem norma. l I presume switching the light off casues a voltage spike on the mains but this is an irritating problem and I worry it will damage the computer. Does anyone know anything about this problem and a fix for it?

Most likely the set has lost vertical sweep or the feedback from that circuit. This will shut the set down to prevent a horizontal line from burning the face of the CRT. This will have to be looked at by a technician.

Fixture not working after bulb change


"CFLs" Compact Fluorescent Bulbs (with built in ballast) must be labeled as dimmable to be used on a dimmer circuit.

Traditional fluorescent fixtures must have a dimmable ballast installed inside and can be used with standard fluorescent lamps.

Fluorescent lamps must be sized to match the ballast. CFL's are matched at the factory, but others are not. Older fluorescent lamp fixtures have a ballast inside. A type rating is to operate (2) 48 inch / 40 watt lamps. Newer fluorescent lamps are rated for 32 watts, and these will not work - or will have a greatly reduced life.

If you installed CFL's, the first thing I would do is install regular incandescent lamps and see if it works as expected. If not, something else is wrong - otherwise - make sure you've got the right lamps in the fixture.

Switch doesn't work


Because the switches have electronics in them the ground wire may be very important to give it a full 120 volts to be able to run. Also double check your lighting, these dimmers are likely for incondescent lighting only (light bulbs). A compact fluorescent or some other lighting may blow the switches. If your lights are led they may not have sufficient resistance so that the dimmer knows that you have any lighting at all. Fluorescent lighting has to high a capacitive reactance and or inductive reactance. Halogen or other lights may cause troubles too. Check the directions on your switches to see if they were for incondescent only or for fluorescent only etc. Also modern bulbs don't seem to screw far enough into the sockets because of their fat necks that bottom too soon. You may have to turn off the power then put your finger inside to bend the bottom contact up enough to touch the bulbs.

Why cant i find any thing about fluoresent HOUSE lights on here


It could be because you posted this under electric fans instead of lighting. You need to twist the fluorescent tube 1/4 the way round to release it from the tombstone ends. If the fitting is old this can be hard to do and the tombstone ends can become brittle and break.

I need a fluorescent dimmer switch that turns lights on & off and dims the string of lights also.


Hi,

Lots to choose from, depending where you are located:

http://www.google.co.uk/products?hl=en&source=hp&q=fluorescent+dimmer+switch&um=1&ie=UTF-8&ei=4-ppS7GaNIz40wT5kvhi&sa=X&oi=product_result_group&ct=title&resnum=1&ved=0CBoQrQQwAA

Generally a Google for a good brand (MK are normally OK) should give you plenty of results.

Hope this helps, if so please leave feedback - if not please let me know and I'll try and help some more!

Two switches with two hallway lights-one delays going on.


What it sounds like to me is that the second light may have fluorescent bulbs - either the compact fluorescent type or maybe a circular bulb. The fact that when you turn off the switch and then immediately on and it works fine, also makes sense if that is the case.

Brightness keeps shifting on Samsung 46" 7 Series 750


I just purchased Samsung series 4 LCD TV yesterday. I had the same problem since my salesman was a kind of stupid. He set the 'Power save mode' to automatic. After fiddle with my TV for a while, I found the solution.
Just change the 'Power save mode' to off, low, normal or high. My LCD TV stopped shifting its brightness.
