Either get a newer HDTV antenna or have the Cable or Sat company check the signal. If that does not fix it then replace the Main bd.

One tv channel is out of voice sync all the other channels are fine how can I fix this.... I have tried re tuning


as there are two different band to carry voice and picture, they are synchronized at the receiver
AS it is only on one channel , that suggests that it is the transmitter problem
Sometimes by simply moving to another channel then back will allow it t fix itself

My tv keeps saying no channel I the list and when a retune it it picks channels up says scans complete but keeps asking me to retune


Its main system memory IC is defective. Replacement should be done. Contact any service technician. The IC will look somewhat like these.

It can be located very near to the main system control IC. One example picture is given here. Your TVs might be different. Thie picture is only for comparison. See that IC marked in square.

I need to see a wiring diagram of an MPX 210 speaker box. My brother-in-law bought one from a friend and someone completely jacked the wiring. I just need to see how it should be wired. Pictures would be...


It really depends on what subs you are mounting in the box. If you are mounting single voice coil subs, it's easy. positive of the sub goes to positive on the inside of the box and the negative of the sub goes to the negative of the box. Then you would repeat the process for the other sub. Then wire the box to the amp using the push or screw terminals.

Now if you have dual voice coil subs, that's where it can get tricky. You really have to know what amp your using and what ohm load it can handle, and how many channels you will be using.

I'm going to give you an example that has two dual 4 ohm voice coil subs. Let's assume you will be hooking them to a 2 channel amplifier that is 2 ohm stable.

wire the positive of both voice coils to the positive post of the box. then wire both negatives of the voice coils to the negative of the box. Repeat the process with the other sub. This is called a parallel set up. Two 4 ohm voice coils wired this way will produce a 2 ohm load. since your amp is 2 channel, you will hook the positive and negative to the positive and negative of one side of the box, then repeat with the other channel to the other side. This will allow the most power to come out of a 2 ohm stable amplifier.

If you have something other than the equipment I gave you an example of, repost with your equipment specs and I will walk you through it.

No picture


It sounds like the LCD controller board is bad. There are more than one versions of this board because this brand of TV are made by more than one manufacturers. You need to get the number printed on the circuit board and look here: http://www.shopjimmy.com/catalogsearch/result/?q=Insignia+IS-LCDTV32+

PS3 Audio Output Problems


Inside of most any system there is what I like to call the sound chip, I am not sure what the actuall name ofit is. This sound chip is the final stage of amplification of the circuit board before going out to the any other sound device. I have found in several cases that this single chip goes bad. Depending on what brand it is the cost to replace this single chip can be anywhere from a few dollars up to a little less than $100. As for the being able to hear certain parts of saound what is happening is the chip is divided up into several different channels thus if just a few channels of the chip goes out all you would hear is the background noise or nothing at all depending what you are playing.
