Mitsubishi cs-27tx1. Only has a thin horizontal line thru middle of screen


Hello

Total Vertical Sweep failure had occured in your TV. That is there is only horizontal sweep there, and the whole picture sweeps horizontally and you see a horizontal nice line across the screen, at the middle of it. In this case, all other buttons will work, and sound output will be Ok.

This fault is normally due to Vertical Sweep Out Ic trouble. You have to open the back cover of your TV, and have to pull the main board out. Locate the Vertical Output Ic. It is easy to locate it. There will be four wires going to the deflection yoke assembly [the coil fitted alongwith the picture tubes' neck]. Amoung them, two will be thick, and is carrying horizontal sweep signals. The other two wire are comming from vertical sweep section. Follow the wires and find out from where it comes from the main board. Somewhere near it orginates from the main board, you will see an Ic usually screwed into a heat sink [ a metal plate or so]; and it is vertical output Ic.

Check first, whether there is input voltage [working voltage] come to it or not. Sometimes an open resistor problem may occur to show this fault. Normally vertical section will have a voltage rating between 18 to 35VDC. If that voltage is there, surely the Ic said above is damaged. Screw it out and desolder it from the mainboard, and go for an identical type and number, replacing it will solve your problem.

Take all precautions when we works with an elctrical equipment. Keep away children and never allow even stand beside you while you are working, and let an adult beside you as a precaution. Never use metal chair. Do wear a plastic of rubber shoes. If can, keep matted the floor also with carpet. Ok
Wish you success.

I have a Mitsubishi CS-3125R that displays a horizontal line with sound. I suspect the horizontal transistor is out and cannot find one. Any ideas?


You are misleading yourself. When you have a horizontal line across the screen it means that the vertical circuit is not working. You see, the vertical circuit moves the beam up and down which is not happening. The horizontal circuit moves the beam left and right and it is working. Your set probably needs a new vertical output IC and some electrolytic capacitors that work with it. The caps dry up with time and harm the output IC.

Tv problem


The vertical deflection circuit has a fault. 
Try hitting (not to hard). If it comes back, even for a short time, it is a cracked circuit or solder joint.
No results, there is an IC responsible for the picture to become whole again

Horizontal line across my tv


This is a problem with the vertical circuit and is relatively common. If you can solder you can fix this yourself. First try resoldering the pins on the vertical IC. If that fails to resolve the problem, replace the IC. This IC is a small flat IC attached to a heatsink having about 11 pins or so. Is will be marked LA7837 or something similar. Post the marking here and I'll confirm the part.

Keep us posted.

Single Horizontal line


The vertical IC has failed. Open up the back and look for a small flat IC attached to a heatsink. It should have about 11 pins or so and be marled LA3847 or something similar. First try resoldering the pins as it is common for the connections here to go bad. If that fails to resolve the problem, replace the IC.

Keep us posted.

TV problem


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.

Vertical Sweep


If the quality of the picture was good before it failed it is worth repairing,replacing the vertical Ic should take care of your problem and for a service technician is a fairly easy repair and they usually dont charge too much,maybe 100.00 to 150.00,if you take the set to someone is less the charge but I know is heavy and it might not be an option,shop around for the price of an estimate in your house.
