Question about Sharp LC Televison & Video

1 Answer

No picture, has sound. Black screen with green lines.

Turned my TV on and there was no picture but multiple green (possibly yellow and red also) horizontal lines running through the screen. Turned off the TV and turned back on, and the picture came back up. This happened a few more times until the final time, no picture came on after multiple power offs and ons. Left the TV off for about three weeks thinking it needs to be replaced. I turned it on again randomly just last night and now the picture is fine again. The TV is about 7 years old. Should I just replace it or do you think it's a cable issue?

SOURCE: Red Light Flashing 6 times

When the lamp fails in this unit, often the thermal fuse opens. The error code is 6 blinks. To replace this part requires a great deal of deal of disassembly.

Some of these have a 4 pin test on the control board that you can jump with solder to get test pattern. If you get it to do that then these boards maybe good and would replace the control board. if nothing happens, then
the upper & lower drive also the Ysus and Zsus boards all at the same time.
last could be a defective panel.
hope this helps. p/n are on all the boards.

SOURCE: power button is green - no blinks / no picture / no sound

Unplug it from the wall, wait 2 minutes and plug it back in. if problem still exists, its probably the main pcb.

Why does my tv have one blue, one red and one green line at the top of the screen but no picture?


The CRT inside the TV has gone bad. You can either find the make and model of the CRT and replace it, or get rid of the tv and buy another one.

Hello, i am trying to hook up my xbox 360 to my


Make sure the tv is set to A/V 1 if it has multiple A/V hookups make sure the tv is on and set to the A/V channel you are trying to use. And make sure your cable is set to tv if you have a composite cable. If that does not work try buying a composite cable (thats the yellow red red blue green white cable). If that does not work. There might be something wrong with the xbox or tv.

No picture or sound mitsubishi 62525


Capacitor failure is the most likely scenario the FMT ans Signal PWB would cause the picture interference and the power pwb would cause the lamp light to turn red and give a 34 code when the device/ input and menu buttons are pressed in together and held for five seconds. That chassis has issues with every board in the chassis having failed capacitors you can get repair kits for the V26 chassis at the follwing link that come with instructions. Your model is the V26 chassis. Heres the link.

Toshiba TP50G50 Theaterview picture is double with red color only


Your alignment is off. Go to the set up menu then convergence. hit right and you will be in the convergence menu. select the color that is not in alignment. The green line does not move. if blue and green are lined up the line will be cyan. if red and green are lined up the line will be yellow. when all three are lined up the color will be light. Best of luck!
