I've scoured the internet and have finally settled on
submitting my issues in hopes of understanding my problem and maybe
finding a solution. I own the below mentioned TV had have for at least 2-3 years, manufacture date on back is August 2004.
6 months ago I started to notice discoloration on the right side of the
screen running vertically (red). Eventually on the Left side as well
(green). I know this is a picture tube issue. Very small fridge magnets
seem to help fix the picture slightly (and temporarily)
when ran across the effected area. The set has never been dropped or
otherwise mishandled. I don't believe any items near it would generate
any kind of interference either.
I have continued to watch DVDs and play games on it with some mild visual discomfort. I just dealt with the issue until now. Occasionally
the visual flickers slightly and seems to be adjusting itself, as if it
was degaussing but then goes back to the discolored visual.
guess I'm curious what could have caused this and if there is really
anything that could be done to try and troubleshoot this issue before
giving up on this set.

Re: Picture Tube Failing
HI... I t sound like the De-gauss circuit has failed. De-gauss demagnetizes the TV tube so you dont get what youre seeing. It could be something as simple as a solder joint on one of the parts in that circuit. I fixed my Panasonic that way

Hello .I understand this situation very much so , I had the same issue.. You must call your Internet provider you are with to walk you step by step through the process on how to connect your tv to the Internet .Sometimes it get's tricky . Ask for tech support. It worked for me . Hope this helps .:)
There are two common scenarios with these Thermador wall ovens fitting what you've described. The harness to the display from the control board is loose (not likely) or the display itself is failing (most likely). The issue with these displays is they lose their intensity over time because of the fluorescent tube technology they use, hence the only remedy is to replace the control/display kit...the display only is not available, but a "kit" is.
You can find these "display kits" at "repairclinic.com" and similar to what I've attached here... **Your other option, and the one I recommend, is to have the existing display and control rebuilt...the down side is this will require the parts to be removed and sent away** You may find other suggestions or "band aid" remedies on-line, but in my experience this is the sure way to go. Here you'll find all the info pertaining to this option by clicking on the link I've provided below
Your power supply board is failing and when you wiggle the cord it is turning it on and off until it finally starts up. There are parts called capacitors that start failing and it will cause intermittent power issues such as slow to show picture, flashing power button, wavy or flashing picture. The board can be repaired and the monitor will be as good as new. Here is a picture of the power supply with the parts circled that need to be replaced.
There is a step by step repair guide for the Samsung 2493HM unit here:
In many many cases this is an indication of a failing picture tube. The gun assembly in the neck of the picture tube is shorting. There is a fix, but this is surely last resort and the final cure may not provide a fix. Picture tube rejuvenation is not always successful. I would certainly opt for a new TV. Thanks for asking, and show a few hands of support!
Your set, with a dark screen or no picture but with sound is failing in the high voltage to the picture tube. It is caused by a failure in the horizontal deflection circuits which generate the high voltage (20,000 volts). The repair is expensive; at least $100 or more, most likely, depending on exactly what components have failed. Regards
I'm not quite understanding what the issue is. Is it this just bugs you or do you want to know if the fuel level sensor might be failing. Unless its causing engine malfunction or fuel pump problems I personally wouldn't worry too much over it. I would bet that fuel level sensor is failing, this sensor is part of the fuel pump assembly. With a car this old fuel pump issues are quite common.

It very well could be the Blue CRT shorting out. However the not shutting off is not a symptom of the tube being shorted that sounds more like a signal board issue rather than a picture tube, as the signal board can cause all the symptoms you have described.
