Retarce line

Diagonal retrace lines at the top are usually the result of bad electrolytic capacitors in the vertical deflection circuit most vert. deflection circuits derive operating B+ from a horizontal flyback transformer winding rectified & filtered usually around 24 volts the electrolytic capacitor on this supply loses capacity or may totally go open causing the retrace lines,sometimes other electro. caps in the vert circuit can cause this too, depending on the age of the tv you may find multiple substandard electrolytic caps it's best to test all for capacity & esr. Without knowing more details about your tv brand,model and/or chassis i can't help further.

Blurred picture on screen, distorted sound with vertical retrace lines?

It sounds that either the screen voltage to the G2 grid of the picture tube, or the smoothing capacitor connected to the video output supply voltage has the fault. Replace the capacitor mentioned above. The value to this capacitor will be in between 10 to 22 MFD 350V or so.

White horizontal lines on top of screen

Replace all the electrolytic capacitors in the vertical output section circuit. There will be 5 or 6 of them. Replace the at one time. The fault you see is technically called " vertical retrace lies".

TOP RETRACE LINES

What did you use to check the caps?


retrace can also be caused by the master screen being set too high.

I WAS WATCHING MY SAMSUNG TV MODEL LN32A450C1DXZA AND WHITE LINES APPEARED ON 3/4 OF THE TOP PORTION OF THE SCREEN, HAD THE TV FOR ONLY FOUR YEARS

This fault is due to leakage of electrolytic capacitors in the vertical stage that is why top retrace lines are visible over the picture,if you are technical person check the capacitors in the vertical stage by replacing the same.

Several lines run across the top of the screen

Several lines acroos the screen at the top along with picture is a typical fault. You are seeing vertical retrace lines. Either the supply smoothing capacitor to the power supply given to vertical output Ic or vertical output capacitor connected to the vertical output pin of that Ic may faulty. Usually the supply smoothing capacitor seen faulty. It may be over 1500Mfd eletrolytic capacitor used there. It may get value reduced by 40 percent or so, this falult will occur. Please replace the two capacitors together and will get the result.

Retrace lines in top of tv...

These lines are cause by defective capacitors in the vertical section of the TV. No adjustment will work unless the capacitors are replace. The values of the capacitors are between 1uF, 10uF or possibly a 47uF.
I do not have the service manual at this moment but you can google it by the model number of your TV.
Let me know if you need further assistance.

Screen went full bright one day.

Hello, please check the 10uf/200V capacitor around flyback transformer. Best regards, Arpi
