Question about Televison & Video

1 Answer

Hello, I have Samsung 46 tv less than 2yrs old, when you turn it on there is shadowing and three horizontal lines on the tv. However, after about 15-20 mins the shadowing and lines disappear. I thought it was the cord, but it does it when playing a dvd and when i put it on cable. I checked all the leads to see if any were loose, I looked at the capacitors to see if any tops were bulging, and cleaned the t-con ribbon -nothing worked. Please advise if there is something I am missing or does it sound like a control board issue.

I'm afraid, it is lcd panel (screen) issue that can not be repaired and only solution is to replace lcd panel (screen) that would cost you approx 80% of new tv cost.
Thanks.

This can be an issue with the Timing Control circuit board, but that is just an educated guess.

Our three year ol Samsung TV has dark horizontal lines across the top of bottom of the screen. It is getting worse


Welcome to fixYa!

When you see lines like these across your LCD, it indicates a problem with your monitor's electrolytic capacitors.A faulty filter capacitor in the power supply board (SMPS board) can cause horizontal lines across your monitor screen.Horizontal screen lines are one of the most visible problems I see in LCD monitors & TV's that are 3-7 years old. It can happen as much from heat, humidity & less-than-ideal operating conditions, as it can from fluctuating current supply or manufacturing defects.

The way to repair horizontal screen lines is by removing the capacitors from the printed circuit board (PCB) and testing them with a LCR meter.

If it shows zero, there's your confirmation that the specific capacitor needs to be replaced.

now if you can replace them your welcome but i wont suggest that , cause you may break it more....!

any ways do comment if it helped you in any manner!
