Can't advise on entering setup but the lines may be due to the maladjustment of the brightness control on the flyback. There will normally be two adjusters, one for focus the other for brightness.

My 27" ( aprx 6 yrs old)Tv first had only a horizontal line across the screen about 1/2" wide, good sound but no picture, now it only clicks like its turning on and off when you plug the tv in, no pictue...


It has gone into a self protect mode where it will shut down because you have a fault in the frame stage of the TV (horizontal line). This will most likely be a failure of the frame output IC. Replace this & you should restore the normal picture.

Since Intermitant always inspect the vert ckt for bad solder connections. If not replace the output IC they're cheap and most likely the problem If you still have lines on the top or bottom I would replace all of the electrolytic capacitors in the vert ckt also. Without much test equipment rebuilding the whole little ckt is the best way to go.

The vertical output IC or the vertical circuit is whats at fault. its all solid state and im sorry to tell ya that its not a user replaceable part. This set is probably not worth the repair it would take to get this set working again but please if you like ask a ;ocal repair shop what they thought about this problem.. Good Luck and please dont forget to rate this thread

One thing you should not do with electronic devices which have a start up proceedure is to turn the power off, and then on again without a wait of about five minutes. Some equipment manuals warn you about this, and specify a longer period. The start-up has to have time to reset. It will be more likely to reset if you do not leave it on standby, and even unplug it. In your TVs case you need to describe the distorted picture as it may give a clue to a fault, or incorrect start-up. The horizontal line indicates the frame timebase had stopped working. No picture could be a fuse blown inside the set, or a timed cutout which may reset after a time. Try after several hours to see if it comes on. If it is just the frame timebase (vertical) it is worth repairing.

If you know how to trouble shoot solid state electronics, you should not have a problem trouble shooting this set. it sounds like a bad solder connection But these sets are not made for a consumer to repair as they are all soldered into placxe and inside a TV set is not tyhe place for a peep to br if he doesent uinderstand thongs

Fixing horizontal line problem


If hitting the set gets the vert to come back then you have bad solder connections on the vert. outputs.. If it dosent then your gonna need to measure the voltage first on the vert output IC see if its about 24 or so volts If it is replace the IC. If its not the replace the vert B+ drive capacitor off the flyback xformer. If you cant find these things then your gonna need to get a schemtic from sams photo facts and post the vertical section and I will tell you or assist youin this repair. If you have had experience in soldering and curcuit work your already ahead in the repair. post the schematic.

Thin horizontal line


Defective components in vertical deflection and output circuit inclusive of vertical output device, coupling capacitors, and yoke connectors. Passive devices such as electrolytic capacitors, coils, and resistors to/from power supply circuits. If your tele is more than 10 years old dump it and get a newer product. $100 USD is a fair price to diagnose and attempt service, depending on age and configuration. Older products may not have replacment parts available at any repair cost. There may be a pot for adjusting the vertical size. If so, it may be dirty. If you can find it, try adjusting it which could clean it. BE CAREFUL -voltages are very high.
