Did you check if 24v supply is coming to the chip ( through a fusable 10 ohm resistor ) ?.Look for dry solder on the sync chip ( 24 pin or 40 pin IC ).

SOURCE: center white vertical line on my t v screen "

Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

Check the 4 pin connector goes to it deflection yoke; from the main board for any loose solder terminals at the main board side.

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.

Type in the IC number, in the search box [at the top right] of the display window, and press enter to get all related posts. It will make surf easy.

I m ramchandra patil, i m used china kit which is used ic hay 22 8873csng6pr6. Eht ok, no picture, no sound. 5 volt,8 volt is ok. Pls give me solution tips. Thanking u


Disconnect the horizontal output transistor, and switch ON the set without it. See whether it switches ON. If yes, suspect both LOT and horizontal output transistor. This is a common fault to this kit. More to say, if the tuner get shorted inside, this might happen too.

Whent he tv is on, we see a thin horizonal line. the sound is good...you can hear what's going on, just a black screen with thin horizontal line. TV is only 2 years old. Toshiba TheatreView SD


HELLO

I wish I had a £1 for every time I answered this! This is field collapse where the probable cause is the Field Output IC itself, or dry solder joints on the board where the IC is soldered in.

If you are not familiar with electronics then I urge you contact a service centre in your area.

ALL THE BEST (:-)
