How to solve horizontal lines on a CRT TV monitor and what could be the possible courses for it


Monitor horizontal lines problems usually caused by a defective vertical output/driver ic. A missing supply voltage to the vertical output ic may caused similar faults which is one horizontal line across the display. Dry joints and missing vertical output pulse from vertical oscillator ic also could contribute the same symptom. If you discovered that the protection resistor (usually from 1 to 4.7 ohm) open circuit or burnt, then replacing it won't solve the problem. The resistor burnt or open circuit was due to a short in the vertical output ic. Thus you have to replace the vertical output ic and the burnt resistor together before you switch on the monitor.

Whic is vertical driver ic and which is vertical processor ic in ny tv... Main ic LA76810 and vertical ic 78040... whic is processor and which is driver ic


LA 76810 is the processor-chroma- oscillator jungle & 78040 is the vertical IC. Refer its schematic for more details. 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/

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.

Circuit diagram TC-29P20B


A single horizontal line indicates "No Vertical Sweep". It is most often caused by a loose solder joint on the vertical output device, (transistor, or packaged circuit).

No vertical output, but vertical ic workng fine,vertical supply ok,


Touch the input pin of the vertical IC, by the blade of the screwdriver, and see whether there is a tendency to change with width of the horizontal line on screen. If so, check and replace the horizontal, video if, vertical oscillator jungle IC. Check the frequency to the input of the vertical scan IC, with a frequency meter. If there is frequency, and still no vertical scan output, check the yoke connection, and make sure that it has no open circuit.

RCA 27 in has white horizontal line going through the middle


this symptons is caused by a breakdown in the vertical deflection circuit. hence, the trouble may be in the vertical oscillator, amplifier or output circuit. in most modern tv the vertical ic is usually composed of these said circuit inside. the ic have many pins, standing on a heat sink and smaller in size. try to check also the capacitors surrounding it. sometimes leaky capacitor may cause this problem. good luck!

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!

Quasar 32" TV VERTICAL HOLD


well most of the modern tv today doesnt have vertical hold anymore. this symptom is caused by a trouble in the IC integrated circuit or the vertical oscillator circuit. let the service guy do the job if u dont know anything about this. good luck!

Take a look at the sawtooth waveform produced by the vertical oscillator. There's probably an IC that's producing it. I'd suspect there is a capacitor that is out of tolerance in this circuit on it's way to the vertical deflection yoke. Hope this helps.
