Question about Samsung LNT4066F 40 in. LCD Television

1 Answer

The TV will not power on. I already replaced the power cord and after the TV is unplugged for a little while and I turn it back on it has rainbow lines across it, whether I have the cable boxed connected or not. Even prior to that it will cycle approximately 6-10 times before it will turn on and at times there will be a few pixels that are not clear and I will have to turn it off and back on again to fix that issue.

TV will not turn back on after it's powered off


The capacitors on the power supply need to be replaced. When you take apart the TV, and then remove the power supply (it's the section that the power cord goes to) and open it up. Look for the little can capacitors and see if any of them are bulging on top. That is the sign that they've blown. Replace the big ones (about 5) for about $5 in parts. Reassemble and test by turning it on. Search for YouTube video on how to replace capacitors.

Cleaning the filter on a e series rainbow vacuum
Posted by jonesjpc on Jul 06, 2008
This one does not have the tabs to depress as but has two screws in that area still doesn’t see how to get to the filter. Also I need instructions to replace power cord; On the E series single speed.


Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. On the Rainbow E Series there really is no actual filter – the water is the filter for this particular vacuum. Before you remove the separator under the motor, place a newspaper or towel under the Rainbow without the water pan under the vacuum and then turn it on for a short period of time and spin the water moisture out of the motor and separator; then some of the maintenance is to remove the separator under the motor and clean that and then replace it. As far as replacing the cord there are screws under the Rainbow that need removal and then you can get to the end of the cord for replacement. The easiest way is to mark your wires and the cord will be much easier to replace otherwise check the owner’s manual for cord replacement or check with your local vacuum cleaner dealer in your area or to cal the cust serv @ the Rainbow factory for questions.
