Hi, More than likely it sounds like something was spilled on the front of the t.v.'s screen and before it was cleaned off leaked into the screen itself. On the bottom edge of some t.v.'s there are the ribbon cables that connect screen to the circuit board, if something gets spilled there it can interrupt the contacts and cause that very symptom ( I know from 1st hand experience- mine was with a 19" Audiovox that developed a rainbow of vertical lines ) The only way to tell is to disassemble the t.v., look at where the ribbon cables connected to t.v.'s screen and check for signs of corrosion ( in my case i could see where the semi-translucent pathways, kinda gold in color, that led from the edges of ribbon cable leading inside the lcd were eaten away) I hope I'm wrong but if not I hope this shed some light on your situation. Thanks for asking FixYa, Good luck-Prodzilla
This is a common problem with this printer. Each toner color has it's own roller. The tin blade on the inside edge of the roler gets plasticy buildup and needs to be cleaned.
Pull out the entire toner roller assembly for the color that is problmatic. Unscrew the tin blade from the roller assembly. Clean the inside edge of this blade (the part that scrapes on the roller) completely. NOTE: After cleaning mine with toilet paper & water I ran my fingernail along the edge to find that the waxy buildup was still there. I gently took my fingernail and scraped at it until it felt smooth -- no burrs.
NOTE: The edge of this blade is very sharp! Be careful. Don't run your finger along the edge.
Reinsall the tin plate maing sure that the foam sweeps (on the right and left of the blade) are not stuck under the tin blade. (If you do, it will dump large amounts of toner on your pages. Very messy).
Sounds like a loose ribbon cable -- the one that connects the screen to the circuitry inside the camera.
Try squeezing the body of the camera near the bottom 'Samsung' logo, to try to snug-up the connection. Brace the front (under the lens) with your index fingers, and press firmly with your thumbs on the back over the logo just under the screen.
You might try squeezing around the other edges of the screen for good measure in case something else came loose.
Does not sound like the chips are bad. What you need to adjust is "SKEW". You need to enter "service Mode" then go into "Coarse Convergence". Skew can be adjusted for all 3 colors. Unless you have the service manual, these corrections should not be attempted.
To clean the INSIDE of the screen, you really have to disassemble the TV. Remove all the screws that hold the "back" ( the piece with the mirror) to the front (screen) assembly. The screen can be cleaned with a solution of diluted isopropyl alcohol, no more than a 50% solution. Drugstores will carry it, but it might be 70%-90%. Just dilute with distilled water (not tap water as it contains minerals). Personally I have used 70% with no ill side effects but 50% is recommended.
