Yes , I would go with that , and replace any electrolytic caps on it also , as they can be hard to tell if they are going bad , but some smaller electrolytic caps can be checked on the highest resistor setting( after the cap is discharged ) to check for comparison of same type cap , diodes,resistors and discap capacitors can also cause the IC to go or not function properly

Tv has horizontal line in middle of screen,sanyo ds25390


hi if only a horizontal line across with no video anymore, you have bad either vertical ic or no dc supply b+( vertical ic ) or no output dc coming from the ic. if it is not totally a horizontal white line and you can see a video you must check leak or bulged capacitors at the vertical section near the vertical ic. hope this can help good luck.

Yes, you should still have sound, providing that you have an antenna connected and are tuned to a channel. If you have a vcr or dvd player to hook up to it try that and see if you have sound.
No sound while viewing a tuned in channel or via a vcr/dvd player is not a good sign. It may have cracked the PCB inside the tv. A cracked PCB, depending on the severity, can also be repaired.
You really won't know the severity of any internal damage until it is opened up and checked over.
Is the line on the screen Horizontal (left to right) or Vertical (up and down) and is it centered on the screen? A vertical line would indicate that it may be a cracked PCB (Printed Circuit Board).

White horizontal, zig-zagging lines


It sounds to me like you're describing the re-trace of the unit. It is repairable, and more so the sooner you get it to the repair facility.

White Noise Sound


Your problem is somewhere between the tuner and video detector circuit. The signal entering your TV carries: video,red color,and blue color as well as sychronizing pulses for color and horizontal and vertical deflection ( actually vertical sync. is derived from horizontal sync.) along with burst pulses to synchronize the color. After all these, the sound is an fm signal entwined with a pilot signal for stereo audio. WHAT a mess! After the audio passes through all this, it is detected and sent to the audio processor. If any frequency has drifted away from it's value then you loose the sound. SO... your problem could be in any of the tuned circuits or in the audio processor IC (chip). Any component changing value could creat this problem. Most likely the audio processor IC. You'd need to have the set checked out by a tech to find your problem. Stargazer
