SOURCE: 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.

did you ever check the jungle ic supply? that is 5volt if the 7805 ic is over voltage replace it!

SOURCE: how to locate vertical output ic on mainboard

This should be a small flat IC attached to a heatsink and will be marked TA8427. I think this one has about 11 pins in it.

SOURCE: vertical line in center have replaced vertical output ic

If the line is vertical then the problem is no horizontal deflection. The vertical chip is probably fine.

Check connections around yoke (thats the connector with at least four wires that goes up to the coils around the neck of the tube)

Maybe that TV has two horizontal output transistors. One for deflection and one for high voltage? Check both of them. Look for bad solder joints!!!

SOURCE: unit has sound, no vertical deflection. caps and

If there's an audio,,it might be the defective Vertical IC...but check first if there's 24v-26vdc supply coming from FBT going to Vcc of Vertical IC.

If there's no Audio,and only white horizontal line in the screen,check the Vertical out of Jungle IC.

Good luck!

I have a sharp tv. the problem is when i turn on the unit it shows a single horizontal line then immediately relays clicks then turns to stand by mode. i already change the vertical ic.


Vertical scan output failure. That is the reason for this horizontal line, right across the center of the screen. Check and replace damaged component/s at it vertical scan output section circuit. Check the solder terminals of the vertical scan output IC; for any loose solder points. Contact any service technician, if you're not handy in electronics.
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/
Line, faults & possible causes to TV screen are given with illustrations. You can get an idea about the fault to an extent.

Denotes the absence of vertical sweep. Check all the solder terminals at the vertical output IC for any loose soldering. If this IC do not get its supply voltage, or, if it is faulty, or, any connection tracks to vertical deflection yoke is open, this kind of fault can occur. In this case, as there is horizontal line on the screen, TDA1930 is working. So, troubleshooting should be concentrated to its vertical scan output stage circuits. Check for any bad capacitors too. There will be 5 to 9 electrolytic capacitors will be there, related to vertical scan circuit. Replace all of them once, not by individual. If you wish to get more details, check the site linked here. Pull up older posts.

Vertacal ic overheating and it cutting off after working for 5 min


Check the related capacitors connected to vertical output section. Check whether IC has screwed tightly to the metal heatsink. If these do not help you, replace the IC.

Only a horizontal line can I see in my TV


In most cases the vertical output IC and possibly a fusible resistor off of the high voltage transformer are bad. The vertical output IC is located on a heat sink and usually right next to the vertical yoke winding connectors that are green and yellow in most sets. Please take a moment to rate my answer..Thanks...

Horizontal retrace lines at top of screen


Change 100uf 50-63volts capacitor next to the vertical output ic,if not solved check the vertical b+ filter on the 24volt line.If nothing else work try damping the vertical yoke with 2 300ohms resistors if in series or just one 220-330 ohm resistor if its parallel vertical yoke windings.

Older Sharp TV 19'' that's screen keeps dropping to just a line across then pops open when tapped on it's top.


it s a cold solder at the VERTICAL OUTPUT IC , require a soldering tool , go to the VERTICAL section ,look under the IC to check all solder , hope it helps , AJ

Turns on but quickly turns off


hi

you have defective power oscillations! in this model you have to replace the vertical output ic. because the power oscillation for Jungle IC is passing by from Vertical output.

Thanks!

Sharp 25" tv unknown model (no av in)


It is a simple trouble, tv has got dry solder joints in the vertical deflection circuit. Resolder vertical output ic pins and related components, this will be okay.
