Channel info pixilated, distorted, HD works intermittently

I've had my Mits for about four years and recently the channel information is distorted to the point that it can not be read. Any suggestions on the cause? Also, recently when I attempt to switch to HD, the set acts like it doesn't have an input. I've verified that the signal is entering the set but the set doesn't find HD or digital signals. Thanks for any assistance

My 787 receiver is 10 years old. It worked excellent all these years . It developed distorted sound in the front left channel. I swapped speakers and confirmed that the problem is with the receiver front...

The problem will be in the power amp for the the left channel. One you have identified this on the circuit board you can compare the channel with the right. As they are both the same. Start with a visual check. If anything looks odd compared with the the right replace it. Distortions are often caused by a burned resistor. Though the main power transistors or IC can cause it too. If you can't find anything visual I would replace the main output device(s) for the left channel.

Check in the manual or with the manufacturer, but the TV should auto configure the picture based on the signal.
I have a Toshiba that does the same thing.

There is no mistake when HD is in effect, as the picture is superb.

Pixilization on non hd channels with hdmi cable connected to HDPVR receive. HD channels come in crystal clear, non hd channels are all bitmapped and horrible

Your TV is not at fault, it is showing you the difference between HD and non HD channels. HD TV's work great with HD scorces but don't usually look that great with standard definition, Also the non-HD channels are more likely to be heavily compressed which makes them look bad too.

Samsung LE26R7 4BD, approx 4 years old, colour distortions

Check all of your cables on the back of the tv and your sources such as Cable,Sat box and DVD palyer to make sure they are fully inserted into the input and output connectors. Some times Component cables will work loose and you end up with a missing color. Temprature changes can affect intermittant connections. If that does work then you have a bad Main bd.

Speaker distortion when amp is on for a couple of hours

Check out the Bias resistors in the that channel then compare with the right. You might need an Ohm meter to do it, but the resistor(s) could look burned.

Surround sound distortion

Receivers like this will incorrectly decode rear channel audio and pass it on to the rear channels as distorted audio. Make sure the source being used really has rear channel information encoded into it. It could have other issues but check this first.

Hey guys, I have a Mitsubishi WS-65807 65" Rear Projection Television, and when I press the power button, the green light comes on briefly and the TV shuts down. I get error code 2-3, what can I do to It has been in storage for about a year, but I have used it for a few days without problems. All of the sudden, it shut off while I was watching Netflix. I powered it on and it stayed on for about 60 seconds before shutting down again. I did this a few times thinking maybe it was a chance problem. Now it barely powers on for a second. After doing a diagnostic test using the Menu and Input buttons, I have found that the error code is 23, or a horizontal deflection failure. I am not sure what exactly this means or how to fix it. If you need anymore details, let me know. I will be happy to provide them. I'll even throw in my email address per request to make it easier.
