My 52 inch RCA Home Theater Primiere will not turn on. When I plug it into the power outlet, it makes a chirping sound and will not stop. There is no sign of power getting to the components inside. Please help!

Hi
A common problem for these is bad capacitors in the power supply, Remove the back from your TV and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps

Can i put an extra sub woofer on my lg da3525 via the woofer out socket and what plug do i require to do this


Hi,

How to Connect 2 Subwoofers to One Receiver

Subwoofers produce the deep bass sounds that give home theater the realism of being at the movies. A good subwoofer can rattle the walls during action sequences, while adding depth to recorded music and a heightened sense of feeling in the midst of a televised sporting event. Because most home theater receivers are equipped with a single subwoofer jack, connecting a second subwoofer requires a simple audio adapter available at electronics stores. Self-powered subwoofers have their own built-in amplifiers to drive the bass speakers, so they cannot drain power on the main receiver in a system and thus pose no danger to the equipment, even when an extra subwoofer is connected.

Things You'll Need:

Home theater receiver
Y-adapter with RCA jacks on two ends and an RCA plug on the other, available at electronics stores.
2 RCA subwoofer cables
2 subwoofers


Instructions


Plug the Y-adapter into the home theater receiver's "Subwoofer OUT" jack.


Connect an RCA subwoofer cable to each jack on the Y adapter and route the cables to the subwoofers in the room. Because subwoofers deliver an omnidirectional sound, the boxes can be placed anywhere they won't get in the way, but within reach of an electrical outlet..


Plug an RCA cable into the "Sub IN" jack on the back of each subwoofer.


Connect the subwoofers to wall outlets and turn on each unit by pressing the power button, typically located on the back panel.


Adjust the volume and crossover settings on each subwoofer as desired. The crossover adjustment knob tells the subwppfer which low-end frequencies to reproduce from the audio signal, such as a movie on DVD. All frequencies higher than the crossover setting will be transferred to the other speakers connected to the receiver.



Tips & Warnings

Use subwoofers that are closely matched in power, as rated in watts, when using two subwoofers in a home theater setup.

Disconnect the subwoofers from the power supply while making the audio connections.


Have a nice day...

RCA 52 INCH D52W20B WON'T COME ON


A 1995 60 inch rca good picture and sound. Then it started a cracking noise and a hissing sound, then the picture went blurry. then it was nice picture and sound, then it died. took the back off and turned out the lights. Plugged the tv in and out from the wall socket and there was a sparking noise and a small arc when i plugged it in and out a few times ,at the part that the power plug plugs into.The white part that is beside the white power plug part has thick red wire coming out of it and goes into another plug that has more red wires in it. but the big white part beside the power plug part looks burnt and has black powder on it. that part is probably the problem but maybe not, what it the name of that part and how much would it cost and is it plugged in or soldered.

LG 47" LCD TV - 47LC7DF Clicking Noise


I was told that these clicking noises (which happen on my Magnavox LCD too) were due to the "power required" at the internal switch. Seems that the power required to immediately turn on the TV is too much for a standalone household outlet, so it "surges" power in a series to get enough there. Hence, the clicking sounds are actually mini power surges to send more power to the internal circuits to turn the TV on.

If your set is like mine, these noises generally stop after a minute or two, correct?
