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.

SOURCE: tv repair

A vertical line means the line is up and down in the middle of the screen. That would indicate that the vertical IC and the surrounding components are working perfectly. A vertical line as described is the result of a lack of horizontal deflection (to move the beam from side to side) Since the high voltage is obviously OK, the problem is most likely a bad solder connection in the horizontal yoke circuit. Examine the bottom of the PC board in the area of the flyback transformer, and yoke connector (has four wires Red, Blue, Green, Yellow).and the pincousion coils, capacitors, etc in between. Flexing the board in that area may cause the problem to come and go. Resulting arcing should also be visible. BE CAREFUL, as hazardous voltages are present in the circuit!

SHARP 21 TDA9380PS/N3/3/1664 .TV IN STADBYMODE


Check the main board for fault. Power-On signal is not coming from it to main power regulator board. Check for the reason. If you wish to get some details, http://electronicshelponline.blogspot.com/ Pull up older posts.

Check the horizontal output transistor. Replace the same. Collector to base, or collector to emitter short to this transistor is a common case. If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window.

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...

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.

Re:tv


Hi Redd, You might have better luck posting this under Sharp TVs: http://www.fixya.com/support/sharp/standard_televisions The black lines at the top of the screen are usually an indication of a problem with the vertical output section. It's often bad electrolytic capacitors, the vertical IC, or both. That's apparently not a US model, so it will be hard to find the values but you could contact Sharp Philippines: SHARP (PHILS.) CORPORATION [Philippines] Km.23 West Service Road, South Superhighway, Alabang, Muntinlupa,Metro Manila, Philippines Tel: 63-2-842-1371 Fax: 63-2-842-0530 Service Center Tel: 63-2-807-4991/4992 Fax: 63-2-807-0388 Home Page: http://www.sharp.ph/ Good luck.
