Question about Televison & Video

Open Question

Avol television So ive had this TV for a while and now everytime i turn it on, it displays a dark blue screen or sometimes a black screen with random colored lines and the screen slowly gets white, or sometimes the picture would show but then it would freeze with a sorta white glow and then slowly turn the center dark brown and then black leaving the edges white, i dont know whats wrong with it. it fixes itself after like 30 mins it flashes back to the light blue screen like nothing happened. sometimes when its not displaying the picture i slightly hit the back of the TV and the picture would display but it would be flashing then slowly the flashing would disappear and then the TV would act normally again, im sick and tired of having to wait 30 minutes or greater just so i can watch tv shows or play xbox. what can i do?

SOURCE: Blue/black vertical line in the middle of screen

Sounds like a bad connection on a ribbon cable or plug comming or going to the LCD display. This is something you should not try to fix as these circuits are very very fradgile and you can easily break or tear a ribbon cable . Call the manufacturer to get a tech to assit you. Good Luck

SOURCE: rolling picture

If your Television is not warrantied, there should be rca, vga, and dvi connections you can use with your pc and video card. Since I am in usa I have know idea what freeview, skybox, or scart are.

SOURCE: DIBOSS tv shows no picture

Me too! Apparently Diboss are no longer trading, so no help there. I am aware that these panels have a common power supply issue, the faulty chip is only available from China and the last one I fitted only lastest a couple of days. However the fault described above is not the same. I've checked the psu outputs; all are fine and nothing changes when the picture disappears, therefore I can assume that I'm not looking at a PSU fault. As Iain says above, it appears to be a signal link, however I have no picture on ANY input and without circuit diagrams I cannot find any component that's common to all the various inputs. This leads me to think that either the backlight, or the screen itself is faulty. I'll keep trying and if I get it sorted I will report back.

SOURCE: samsung tv turning off by itself

I had a similar problem where my 61" Samsung DLP was turning itself off very frequently I had resolved to try replacing the bulb. I called a local TV repair place to see if they had my buld in stock. The guy I spoke to actually told me how to fix my problem! There is a little blue switch behind the bulb access door. The inside of the door has a little piece that presses the switch down. The switch is supposed to work correctly weather the switch is in the up or down position but samsung forgot to take expansion from heat into account. If the switch is held in the upper position by the door and the plastic expands to a certain point, it triggers the set to shut off. This does not occur of the switch is held in the lower position. What you need to do is take the access door off and put it back on by sliding it into position from above. That will hold the switch in the down position, eliminating the problem. My set has not **** itself off ever since.

SOURCE: Vertical lines down center of Plasma TV

If it was just a vertical black line, i could definitely solve your problem.  However, i would still perform the following fix if i was you.  It worked for me on my gateway plasma.  Go to the following link and read carefully and follow closely!

Black Screen


Ok, this is probably what has happened, you say that you have played games on your tv, well the thing is with HD and Plasma Screen tv's is that when you play Hi-Res games on them the games backdrop will burn itself into the screen, causing the screen to turn dark and not reveal the correct picture it should. People need to learn about this!!!!! Playing games on HD and Plasma tv's will screw up your resolution!!!
