Black horizontal lines appear after tv is on for 30 minutes

After the tv is on for about 30 minutes black lines running horizontally appear on the screen.  They can vary from the whole screen to several bunches of 7 to 8 lines in each group.  If the tv is turned off for an hour and turned back on the lines will appear inabout the same time frame.

Re: Black horizontal lines appear after tv is on for 30...


I had the same problem with our VS-55705 Mitsubishi. It seemed to me that this was a problem of heat.

I unplugged the TV and then took the cover off of the back of the it. I then used canned air to blow off the collection of dust from the components. Then I vacuumed as close to everything as I could without touching any of the components. I then used glass cleaner to clean up the surface of the three bulbs.

I plugged in the TV and it has worked perfect ever since. I haven't put the rear cover back on it yet. That could have been all that I needed to do to fix it. I'm too busy enjoying a nice picture to try putting it back on. Cleaning the bulbs really helped the quality of the picture.

Good Luck!

We had a blue cone on the screen. We have adjusted the sharpness, contrast, and cross hairs. The cone has almost completely disappeared, but we still have blue shadows. Could this mean a blown color tube?

Any suggestions would be greatly appreciated.

Many thin black horizontal lines on my Hitachi Ultravision 50" TV

Good Day, LDS also;
You may have a poor seated cable connector. Unplug TV from A/C, remove back look for a large black connector. It connects between the Main Digital Module and the Drive PWB. Re-insert both ends several times to make better contact, use contact cleaner if have but not always needed. Good Luck, big IRISH.

Black horizontal lines

Sounds as if you have a bad capacitor in the horizontal deflection or video circuitry. You can spot a bad capacitor in circuit with a ESR meter.Hope this helps.

Horizontal Lines On Screen

horizontal lines = horizontal sync off . mitsbishi always seemed to have this problem .. on the older sets I would take the back off and inside deep on the board i would adjust a pot and sync it right .... and never had a recall, maybe your newer model has this too .. this little control,

but its a horizontal sync problem.

if no change the horizontal processing ic.

No Blue. Horizontal Lines.

Not to me, but it also depends on if you could do this yourself or not. And the area you are in sometimes is responsible for the cost being high.

Horizontal lines

If this model has a "lint screen" or air filter, I would check to make sure the set is getting proper ventilation. Otherwise, you probably have a bad solder connection or capicators going bad, causing your symptoms. Hopefully you won't have to get a replacement Printed circuit board as they are quite expensive.
