Hi Nkokana,

There are few possibilities such as bad quality of vertical ic used, shorted vertical winding and bad components in the vertical ic corresponding circuit.

Hey Mr Justin. I am repairing a Chinese crt TV 54cm that keeps blowing a vertical ic. B+ voltage is 115v and voltage to the ic is 32 which is 78141.no triac to reduce voltage

Hi Amanda,

I'm afraid the internal shadow mask already collapsed causing the color spot and thus it can't be repaired. Before that you can try to demagnetize it using a demagnetizer and iif it can't cure the problem then is the CRT tube problem.

Mr. Yong, I dropped my crt tv.
On the right of the screen is red, and green circles. The rest of the picture is good. The colors are bright and trigger my migrains. Can I fix it?

Hi Brian,

Make sure the B+ voltage is good. If it is good then check for bad modulation diode and the pincushion transistor.

Good day sir

My LG flatron tv's picture is curved on the side instead of being straight and it's getting smaller. Can you please assist me on how I fix it?

Thanks

Hi Vijay,

Check for dry joints in your crt tv board.
