SOURCE: Emerson flat screen tv with red stripe

The pixels on your screen are controlled by a matrix composed of switches that turn off and on to produce light.

They are located vertically and horizontally, row-wise and must function together to produce everything from black (everything turned on so no light, or very little, can escape) to layers that represent the three colors that are used alone or in combination to produce the millions of possible shades of each.

One of the switches that controls one of the vertical columns has failed and has turned on the entire column that allows red to display.

The problem switch (a semiconductor combined with many) is permanently turned on, probably part of the screen assembly itself, and was placed with others by robots.
The pin spacing on these 'chips' is very small and often makes the assembly unrepairable.

While LCD panels have fallen hugely in price, you may be looking at a parts cost (labor is probably not too bad) that may make you decide to replace the set.

Unfortunately, the once-proud Emerson name has sadly been degraded and there is a lot of their electronics available from companies that specialize in 'refurbished' products, an indication that they have a large failure rate.

SOURCE: insignia tv will not powerup

Nothing at all? Does the screen seem to go from dark black to a lighter shade of black?

If the screen appears to stay on the darker shade of black then it is broken, and needs to be sent for repair. ( ie the screen isnt powering on when the tv is and there is nothing you can do without opening it.

You might try unplugging all cables and leaving it off with no power for a day This is in effect performing a factory reset.

and this may sound stupid and patronizing but is the TV being taken out of standby mode and actually switched on?

SOURCE: i dont have a full screen picture

Locate the button on the remote that came with the TV labeled "ratio" or "wide" or " format" not sure what yours is labeled different brands call it different things, but press it multiple times until you get the picture the way you want it to look.

SOURCE: my sanyo plasma flat screen tv will not come on....

For what it's worth, you can download the official Sanyo repair manual for this TV (DP42746) at http://www.eserviceinfo.com/downloadsm/43343/sanyo_dp42746.html. I uploaded it here when I had some issues with this TV last year. The solution almost always seems to be to replace the Power Board and the Upper and Lower Y Buffers. The parts and costs (from Sanyo in July 2009) are listed below (NOTE: Sanyo will not ship these parts to anyone but a repair shop):
1. V4 Y-Main (Y-Sustain) Circuit Board (Part # LJ92-01200A, Alt Part # LJ41-02759A) - USD $139.00
2. Upper Y-Buffer Circuit Board (Part # LJ92-01202A, Alt Part # LJ41-02760) - USD $64.00
3. Lower Y-Buffer Circuit Board (Part # LJ92-01203A, Alt Part # LJ41-02761A) - USD $64.00
Sanyo charges USD $10.50 for shipping, which brings the total cost for parts to USD $277.50. From my research, a shop would probably charge between USD $500 and $700 to do this repair. FYI - there is a class action lawsuit pending against Sanyo for this issue. The V4 Y-Main (Y-Sustain) Circuit Boards fail VERY frequently in this TV due to overheating. Hope this helps.

Why is resolution 1024 X 768 instead of 1365 X 768 like other 50 inch plasmas, this is not a typo


1024 X 768 was known as "The Sony Standard" in PC format. 1365 X 768 is slightly wider screen size, that is all.

The screen is wider than the screen on my tv. tv screen to view is expanded like for a wide screen tv


There should be a format button on your remote control. If your using a satellite receiver or a cable box the format button might be on that remote.

Try searching for it. If one engine doesn't satisfy you, try others. I like to use ask.com because it provided as an option of "safe search" through my norton 360.

What is the difference between psp 2000 and psp 3000?


PSP Slim and Lite (2000 series) 
33% lighter than the original
19% thinner than the original
The redesign also features composite TV output, supports charging via USB, double the onboard RAM (32 MB to 64 MB), and has a brighter screen.
catches UMD data for shorter loading times

PSP-3000
Its based on the Slim & Lite (PSP-2000) design
PSP-3000 features an improved LCD screen, a built-in microphone, and expanded video-out. 
The LCD screen features a higher contrast ratio, shorter response time, and wider color gamut, as well as anti-reflective technology for improved visibility in well-lit environments.
Expanded video-out capability allows gameplay video to be output in interlaced format.

Unless your going to be using a mic, in well lit environments, and are really bothered about pic quality go for Slim&Lite as it is cheaper.

It may be a problem with a cheaper HDMI cable. If the cable is too long or if the cable is of a cheaper quality, you may be able to solve the problem with a larger and shorter "pipe"
