If you are referring to a horizontal line or bar, you will have to resolder the vertical IC. You may also need to replace the electrolytic capacitors that are almost next to the same IC. Now if you have a black vertical bars on the left and to the right side of the screen, you have a horizontal problem. Bad electrolytic capacitors and bad resistors in the horizontal deflection area of the TV board! Thanks for asking and give me a few hands of support!
it looks to me that you are not a technician becouse you are measuring at the wrong places risking a hazard shock if you have a little experience get the service manual and check your power supply and the h v capacitors near the horizontal output if not please take it to your service center
Thus the line connected to a surge protector or some kind of line protector. This can be consider.
Or if this is a crt type tv. This could be a fault on high voltage section. Horizontal output transistor or flyback. But check also for loose connection/solder crack. That clicking sound may be the relay in action.
Hi, your correct it is collapsed vertically, you should have re-soldered it before it failed because now you may have to replace the IC but I would re-solder it first as this possibly will fix it, look for a small aluminum (silver colored) heatsink with a black 7-10 pin IC screwed onto the heatsink, flip the main board over and this IC will probably have 2-3 (or more) pins broken, re-solder with 60-40 tin/lead solder, you didn`t give make & model number so thats all the info I can give you, good luck, BMW Rider
Hi, I have a Philips 29PT9009/12 TV. Recently I have begun to see horizontal green lines on my tv, when either watching a dvd or watch tv. This has gotten worse and now the green lines are more visible and the background is now turned a shaded green. Please help me. Thanks in advance
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.
