Where is horizontal output ic in my t.v?


There is no horizontal oscillator IC. The horizontal oscillation is generated and outputted by the main system control IC LA76810 itself. Refer some circuit diagrams using LA76810 to get more details about the horizontal oscillation output from the IC. Measure the frequency at that output pin. It should be some ever near 15.62KHz.

One horizontal line on TV


Either bad solder connections on the vertical output IC or bad part in that circuit, IC or something else. I presume it is NOT a flat panel set but has a picture tube as no model number is listed.

Thin horizontal line across screen


Hello
You haven't specifed nothing about the model number or brand name of your flat panel teleivison. i assumes that it to be a picture tube based one and posts this solution before you.
A thin horizontal line across the screen with sound output is OK, is the sympton of total failure of vertical sweep. This may be due to failure of vertical output IC or loose solder terminals of that IC. The vertical output IC will heat up while working, and repeated heating and cooling may make its solder terminals to get loose. Just open your TV, pull out the board that contains vertcial output section, turn it upside down, resolder all the solder terminals of that IC by applying a little more solder, without making any solder bridge in between terminals. Check the voltage to the vertical output IC also. If this resoldering method does not help you, replace the vertical IC itself with same type and number will solve your TVs problem. OK.

My 15 year old Toshiba Televisiononly shows a narrow horizontal band in the middle of the screen. Sound OK.


Hiii fairley,

You aren't specsificly dercribe yor tv set.
For common TV horizontal problem ;i.e : White line accross the horizontal screen, horizontal band,etc..it's can solved by replacing the IC Vertical/Transistor, and olso to replace the cap nearest the IC.

For common TV Vertical Problem :i.e : White line at the center of the screen (top to bottom),Vertical band,etc...It's can cure by Replacing the Horizontal IC/Transistor,and offcurse the cap's.

Tha's what all I know....

Hope can help you to solved the problem.

Thank's

Why do you suspect the horizontal or vert curcuits? I would suspect the HV curcuit since no display at all. Gary(Honkity Hank)
