Re: screen seems to flip
All the symptoms in your tv point to a convergence problem,the unit has 3 amplifiers one for each color,this amplifier IC's need to be replaced and then realign the colors,sometimes just by replacing the Ic's you are able to realign the color with the remote but sometimes they need to be realign from the service menu.
You can identify the IC's because they are mounted in heatsinks and by its marking,in the front they have STK--- ---,6 numbers after the letters,their size is about 2.5 " long and 1.5" wide with a row of pins solder to the main board.If you are familiar with tv service this information will help but if you are not too familiar be safe and call for assistance from a servicer.

Check its "Pin-cushion" section circuit for the fault. An IC is used there to control the pin cushion distortion. If this IC has got faulty, this type of fault can occur. This is actually a skilled work. If you are not ahndy, seek any technicians' support.
If you look very closely, is there an extremely dark picture, or a solid black screen?
If it's an extremely dark picture, you just need a new backlight.
If it's a black screen, you either have a bad connection (broken, shorted or unplugged cable), or need a new LCD.
Let me know, and we'll go from there.
This is a pin cushion issue. There should be a setting in the picture menu where you can adjust this. If that does not work than your unit has an issue that you will need a local service center to repair.
You mean the picture on the left side is curved out? Or is it restricted to the very top and very bottom?
If you have the curve problem, look in the menu and see if there is a
pincushion control and a pin cushion balance. Adjust the balance until
both sides curve the same, then adjust the pin cushion control to
remove the curve.
If you are only having the problem in the corners, look in the menu for
a corner correction control and play around with it to see if it
corrects your problem. If the monitor has no OSD (on-screen-display),
then it may be too old to have these controls. You may have to open the
unit and see if there are any physical adjustments (little
potientiometers). You might want to leave this to someone who knows
what they are doing since the high voltage circuit can have 25-35 kV.
Considering the price of CRT monitors, you might be able to find a new
one for under $50.
Try this one: 1. Unplug your power cord from the box (NOT THE WALL!) 2. Wait 3-5 min... No more than 5 MIN (very important) 3. Hold down the power and select button at the same time and don’t let go. 4. Have someone plug the power back in… and keep holding the power and select button. 5.Don’t let go until it gets to 0 (it's about 5 min) 6. Once it gets to 0 then it will stop counting down, that when you let go!! 7. Don’t touch anything, 8. The screen will reset and it will go blank. nad that's it
I had the same problem with my TV, It seems the high voltage trasnformer blew which in turn casued the pin cushion?? to blow. It then shuts the tv off to prevent more damage to it.
$500 with service charges to get it fixed!
