No vertical deflection on a Hantarex 19'' monitor with a eygo 1820-h19 chassis

This is a V20 chassis, circa 2002
Available error codes for this unit are as follows:

12.....No error has occurred

21.....X-Ray protect circuit

22.....Short protect circuit

23.....Horizontal deflection failure

24.....Vertical deflection failure

there are several reasons why picture of crt monitors did not display good picture. if your monitor had horizontal line at the center of the screen?...the faulty is in the vertical deflection, check the vertical oscillator also the fusible resistors & capacitors around that section. if there had vertical line at the center of the screen?..check the horizontal deflection, horizontal output transistor also check the YOKE.

The horizontal deflection coil is shorted. There is no way to fix that, the entire tube would have to be replaced and that would cost as much as a new monitor.
Just buy a second-hand LCD monitor from here

Asta l-am luat eu si are o imagine excelenta.

hi,
Your monitor have problem with vertical deflection section. Can caused by the faulty vertical driver IC and faulty electrolytic capacitor it the vertical section or dry soldering in the pins of the vertical driver IC. When vertical section fails horizontal lines come on the screen. For testing the same you have to open the monitor and remove the main board. you can easily find out the vertical ic. just follow the four wire running from the deflection yoke ( coil on the crt neck) of which two will go to the horizontal section (normally red and blue wire) and two will go to the vertical section ( Normally yellow and green wire). Follow the yellow and green wire which will be connected to one of the socket in the main board. Follow the circuit track in the main board which will lead you to the vertical deflection section. There you can see one ic is fitted on a aluminium heat sink.Take a close watch in soldering of its leads. Dry soldiering can happen in its leads because its a component which will got to a temperature about 75 degree above at its normal working condition. if found any dry-soldering or not just resolder all the pins of that ic. then check the monitor. If problem remains then you have to relapse the ic.While replacing the ic try to relapse all the capacitors in that section. It will prevent from any further damage to the new vertical ic. if you need any more assistance feel free to contact me through fixya

Hello eatkinson,

This denotes a problem with the vertical deflection circuit. This is more then likely the result of the vertical coupling capacitor failing. You will need the schematic diagram of the TV to find the capacitor in question. it is located between the vertical output stage and the vertical deflection winding of the yoke transformer. In addition check the continuity of the vertical winding of the yoke transformer this can cause the same problem. In any event the problem is that the vertical deflection signal is not getting to the yoke transformer or the yoke transformer is malfunctioning.

I hope this helps,

Thank you,

Hello Falken94,

Your TV is losing what is called vertical deflection. This might be caused by the vertical coupling capacitor going bad, or by the vertical deflection coil on the yoke transformer going bad. In any case there is not enough vertical deflection signal getting for the vertical output section of your TV to the vertical coils on the yoke transformer. I would suggest that you get this looked at by a qualified TV technician, due to the nature of this problem.

I hope this helps,
Thank you,

thats a sign of vertical deflection failure. Try resoldering the vertical output ic. The fall may have cracked the vertical output solder joints or cracked the chassis in the vertical section circuitry.

BLACK STRIGHT LINE CAME VERTICALLY WHAT I WANT TO DO your question is not clear. but it suonds me that 1 it is due to deflection connector is loose 2 problem in h/ output section related to hor. deflection coil assembly. good luck.

Your monitor uses one transistor for High Voltage and one for Horizontal deflection. (Many use just one transistor for HV and Deflection). The transistor you removed is the deflection transistor.

Yes. There is no vertical deflection. The circuit that controls vertical deflection is bad. This is an easy fix for a TV tech. Take it to the TV repair shop.
