  • tiffanylee Sep 25, 2008

    I have a 42" Sylvania TV, model# 6824PE and it has no power. It was making a buzzing sound for a while, and then one day went to turn it on and it it made a noise as is there was a short circuit that had blown. Not sure what happened but I turned it off and now there is no power at all. Please help me with my problem, I have no clue. Thank you

    My Sylvania HDTV Model LD370SS8 has the same problem. When I try to turn it on nothing happens.

    I have the Sylvannia 6842PE (42" I think) and it shut off tonight and won't come back. There are no lights, almost as if it is unplugged.

No power and no lights


Follow power cord to fuse inside and check it, total loss of power usually means a fuse or power supply.

Ok, I have recently been the fortunate one in my family to be given a Philips proscreen 4600 b projector. The only problem, so far, is it will not turn on, at all...think that's why it was given to me...


Hello, welcome to Fixya!

Your unit is having a power fault because it is not switching on. The unit might have worked fine in the past, but that's electronics for you. Power surge, irregular power supply, excess power supply, etc can affect the unit thereby not making it to power on.

First, remove the unit's power cord from the wall, wait for about 30mins, then plug it back in. If it doesn't power on, plug it into another outlet, to make sure there electric current entering into the unit.

If plugging into another power outlet doesn't power it on then it confirms that the unit is having a power fault.

When electric current comes from the power outlet into the unit, it goes straight into the power supply board which then circulates the current into the unit. So if the receiver doesn't power on, the first thing is to make sure there is power entering into the unit.

So check the power cord, if it is a 3-pin plug, it must have a fuse in it. check the fuse if it is not blown. if fuse is intact, then power supply board should be checked.

This unit must have a power supply board in it where power enters from the mains. A capacitor, fuse, diode, etc may have been defective on the power board and maybe that's why its not making the unit turn on. There might also be some disconnection or something, inside the unit which is not making it to power on.

To actually find out what's wrong, you need to disassemble the unit with a screw driver and check what's wrong. You will be needing a meter and continuity tester in order to read the components on the power board. Once you detect any bad component, you can make necessary replacement at any electronics accessories store withing our vicinity. This is the only way by which you can detect and solve the problem.

Of course, testing the power board with a meter will require someone that has the ability. So it you can't, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.

I wish you the best of luck.

Regards.

Try first unplugging the TV for a couple of hours, after a power surge the TV often stays in protect mode.

By unplugging for a while, you drain power completely, sometimes this can fix the problem.
