Toshiba 36A50 problem with horizontal lines at the bottom of TV...

I'm having a problem with a horizontal line at the bottom of the screen that moves up and down on the picture. At first it was was not bad but now it's getting worse. Anyone know what might be causing this problem? I'm wondering if it's worth taking to a TV repair shop since its such a heavy TV! Thanks for your help.

Toshiba, 36A50 picture is a thin white line. Can this be repaired?

Yes...this TV may be repaired. The line you describe is in the center and is horizontal across the TV. You will need to resolder the vertical IC pins. This vertical IC is mounted on a large heatsink. Under the board you will see there are 5 or 7 pins that will have rings around them. Resolder these. And you should replace two or three capacitors that are next to this IC. A bad cap will overheat an IC and separate the solder grounds. If you can find my expertise page on this website, you will see the repair in more detail. Thanks for asking and show a few hands of support.

Only thin white line across my toshiba tv

This is an easy repair if you've ever soldered and would not be too costly for a repair shop to do it for you. The problem is a bad Vertical Output IC (usually mounted on an aluminum heat sink with the part on it labeled LA78?? ) and 1 or 2 bad capacitors. Some times you can even fix the problem by re-soldering the contacts of the IC- To find the IC follow the 4 wires that come from the Yoke (which is a contained coil of wires slipped over the neck of the picture tube(s)) back to the board. 2 of the wires go to the horizontal o/p and 2 to the Vertical o/p the thinner gauge wires are for the vertical.

Toshiba TV (about 7 years old)

You had parts in the vertical deflection circuit failing, most common are the vertical output IC and possibly several capacitors also in the same circuit.

Toshiba 36A50 sound, light line horizonally on black screen

It is my guess that you have some intermitent solder connections in the Vertical output circuit.
Hope this helps,

If flexing the board will "fix" the problem, then the most likely issue is poor solder connections on that board. Look for any connections that appear grainy or have rings and resolder them. The IC involved here is the vertical IC which will be a small flat IC attached to a heatsink. It may be marked LA7837 or something similar and have about 9-11 pins.

Try the resoldering and update this with your results.

Toshiba 36A50 Horizontal Line

Ok, The vertical Ic is IC301 Ta8427K And Capacitors around IC chroma 2.2 uf 50 volts. You will see small red capacitor ( with C302....4 or 5 ) reference. Replaced others capacitors on vertical section 220 uf 35 V or 100uf 35V. I hope this can help you. Or if do you have any picture chasis, send to me and I will show you where are the problem., Thank you
