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.
If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
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.

How can I find the part number to order a Vertical Output IC for a Sansui Model tvs2746a


The vertical output IC will have a number printed on it. You mus send this number to get a new one. Normally, all vertical ICs are available from local electronic spare part selling shops. It is not a difficult to get component. Won't cost more too.

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.

TV won't turn on, flashing red light


This indicates "vertical stop," meaning that the TV's vertical output circuit is not working. A number of thing can cause this: failure of the vertical output IC or related components; bad solder connections to the vertical output IC (a common problem); power supply trouble keeping the vertical circuit from operating (also a frequent cause). Without having the set available, it's impossible to offer any suggestions for you to attempt repairs beyond looking for bad soldering. Other troubleshooting would require the circuit diagram (often available from the internet), tools and experience working on a live chassis. If you really want to keep the set and don't feel up to self-repair, it might be worth getting an estimate from a shop. These Sonys are nice sets.

Avm 3259 picture problem


Vcc is on Pin 6 of the vert. output IC so you can trace that back to it's feed resistor (not sure the location number but you can find it easily by following the circuit trace). Depending on what your problem is you may need to replace some electrolytic capacitors as well. Follow pin 7(pump up) back to it's electrolytic cap. and look for swelling or bulging. Look for other bulged capacitors in the vertical section. You may also identify a bad resistor by a discolored look but not always, if in doubt meter it.
Let me know if you need some more info.

Tv cuts off 10 seconds after switch on and destroying vertical output ic


If the main IC is not putting out a vertical drive signal then the vertical output will not do anything and therefore will not be damaged. What exactly do you mean by the set "literally eats deflection IC's"? What is the number on the vertical output IC? I will bet that your pump-up cap or pump-up diode is defective.
