Question about Toshiba 27AF43 27" TV

1 Answer

Horizontal line (with about an inch of picture)

Our tv is about 3 or 4 years old--no problems.  All of a sudden we just have a horizontal line with about an inch of the bottom of the picture with it.  Doesn't work with VCR or DVD either.  Thanks for any ideas/solutions.

Hi.. Mine is a sansui tv and I bought it 3 years back. Now it is showing a horizontal line on the screen. Sound is fine but I can't see the picture, I just see one white horizontal line on tv...

The problem is vertical failure. Vertical output section to your TV ahs the fault. You ahve to check the vertcial output circuit for any component failure or loose solderings.

Vertical line picture

problem is caused by the loss of horizontal deflection signal. It is quite surprising that the entire unit is still working, since usually, a loss of H-Out will disable the entire set. Problem can be as simple as loose solder connection to a more complicated defective horizontal circuit. I would suggest havint it checked by a professional TV tech.

Horizontal Line

This is a problem with the vertical circuit. Look for a small flat IC attached to a heat sink. It should have about 9-11 pins and be marked LA7838 or something similar. Try resoldering the pins first. If that does not resolve the problem, replace the IC. The IC will cost between $10-$20.

If the horizontal lines going through the picture are fine white lines, then I would suspect the picture tube as having a heater to cathode short or some other problem. Since some sets have had a 3 year warranty on the picture tube, you may be lucky unless the labor to replace the tube is more than the set is worth. Sanyo is usually not a good name in consumer electronics anymore, so if you're looking for a replacement I would look elsewhere.

After a household power blips during bad weather, we have horizontal lines ....

Unfortunately there isn't any way to repair your tv as the magnet has distorted the tube that is in the tv and with CRT becoming obsolete the repair is likely to be very costly so probably your chaepest option is to buy a new tv .

Hello Barbara76,
Is this a Horizontal line (inch or two) across the screen, if so
the fault could be either a faulty Vertical IC,Faulty Electrolytic
capacitors or just simple dry joints.

Picture deterioration

Your whole problem my freind is dryed up capacitors. You should go, if you have the technical ability to replace these capacitors, to, download the schematic diagram, and start replacing the waveshaper capacitors in the vertical drive circuit.
