Imagine the flat screen is a sheet, and someone is flapping it forward and backward. That is what my picture is doing, it is strobing, for lack of a better word. It does it on different inputs, so it is the TV, and not the cable or cable box. It just started that today. I have unplugged it for a couple hours to see if it will reset or something. Any other suggestions? Is this something repairable or is it time to get a new TV? We have had it a couple months shy of 5 years.
The problewm of your unit is in the chroma section. if you find a intermittent trouble my sulotion it could be a loose contact layout circuit. and if your not inclined with this job contact for a service technician.

Check out the inverter board. It supplies the backlighting on screen so you see picture. If it is messed up it could be responsible for the flashing. Assuming you see a normal picture in between flashes!
Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board.

"Paper Jam" issues are common with printers. They most often occur right after there has been a paper jam. Most people (not necessarily YOU), don't take the time to read how to properly clear a paper jam in their printers and often yank the jammed sheets backward thru the paper tray. Most times you should remove the cover in the back and pull the jam FORWARD out the rear, or if the jam made it close to the output tray, then FORWARD thru to the output tray. Pull sheets backward can cause two issues. It makes tearing the paper easier. This can result in tiny pieces being caught in places where the printer detect them as a jam. The other issue is that pulling backward can damage the feed rollers that pull the paper into the machine, as well as the mechanical sensors that detect paper jams. If you cannot find ANY shards of paper in the machine, you may have printer damage that results in the jam indication.
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.
I had the same problem with my 237V, I had to replace the power supply to fix the problem. I believe when it would work the output voltage of the power supply was around 19.2v. When the screen started to strobe the voltage had jumped up to 21.5V. A new power supply fixed it for me but now I think my main board is on the fritz.
I made my own with a blank piece of paper and a sharpie. Make a solid black strip about 1.5 inches wide about 1.5 inces down from the top (short edge). about 1.5 inches below that make another one about 3 inches wide. Mine were at an angle but it still worked. feed it striped side down small line first. so esentially the first strip hits the entire width of the scanner all at once then it will see all white again, then all black again but wider this time. then all white till the end of the page. I based my mesurments on a picture so i have no real measurments but mine did work. if anyone has an actual page please take some mesurments and post them on here plz. well hope it works for you.
