SOURCE: Vertical Deflection

If you can still read your serial number you can contact the manufacturer to get the details on this product? EVERY manufacture requires to keep this information on file for years past to current. I know since I've worked for a projector manufacturer. Otherwise, I also found this PDF diagram which might help you out with the number you need: http://www.e-daewoo.com/products/owners_manual/CN115N-010_7.pdf Good luck with your problems & let me know if that helps you out or not.

Hi.

Here IC specsheet:LA78041

Also replace the 100uf/35 volt cap on pin three of the IC and the two zener diodes connected to the IC. That is part of standard repair. If you don't replace the whole lot the IC may blow again.

Here the IC for sale. Cost is less than $5.

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.

Im not sure if vertical output transistors is the prob, but my tv has picture only in the middle vetically, i change the capacitor and ic, but still it didnt work out, pls help.


Hello
Your assumtion is currect. But the vertical output section of this TV has no transistors at all. It is composed of an IC. Check the soldering terminal connection of this IC legs for any loose soldering first. Just resolder all the solder terminals of this IC by applying a little more solder. In most cases this will solve the fault. If not, check all the surrounding electrolytic capacitors to this IC circuit. If found suspected, replace them. Still fault perists, replace the vertical output IC with same type and number.OK.

Loss of vertical sweep


Hello
Your TVs vertical output Ic may be damaged. You just open your TV and locate the vertical section inside, usually panasonic uses Ic numbered [LA7837] which will be marked as part number IC451 on the circuit board. It is a 13 pin Ic, sometimes the number may be different in your TV, as Panasonic uses four types of LA series Ics in their sets. I think that you have some knowledge in the service field, so the complaint states only "loss of vertical sweep", and so I'm not going too deep into description. OK.

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.
