Look for a small flat Ic attached to a heatsink with about 11 pins. That should be the vertical IC. Resolder the pins first. If that fails to resolve the problem, replace the IC and update this note with your results. The IC should be marked LA7837 or something similar.

On screen horazantal white line


May not be an easy fix:

A single horizontal line means that you have lost vertical deflection. High voltage is most likely fine since there is something on the screen.

This could be due to:


Dirty service switch contacts. There is often a small switch located inside on the main board or perhaps accessible from the back. This is used during setup to set the color background levels. (On some sets, this is located on the CRT neck board and may be a jumper plug or other means of selecting service mode - not an actual switch.)
When moved to the 'service' position, it kills vertical deflection and video to the CRT. If the switch somehow changed position or got dirty or corroded contacts, you will have this symptom. Flip the switch back and forth a couple of times. If there is some change, then replace, clean, resolder, or even bypass it as appropriate.


Bad connection to deflection yoke or other parts in vertical output circuit. Bad connections are common in TVs and monitors. Check around the pins of large components like transformers, power transistors and resistors, or connectors for hairline cracks in the solder. Reseat internal connectors. Check particularly around the connector to the deflection yoke on the CRT.

Bad vertical deflection IC or transistor. You will probably need the service manual for this and the following. However, if the vertical deflection is done with an IC, the ECG Semiconductor Master Substitution guide may have its pinout which may be enough to test it with a scope.

Other bad parts in vertical deflection circuit though there are not that many parts that would kill the deflection entirely.

Loss of power to vertical deflection circuits. Check for blown fusable resistors/fuses and bad connections.

Loss of vertical oscillator or vertical drive signals.
The most likely possibilities are in the deflection output stage or bad connections to the yoke

Samsung txm3297hf will not start


R 818 is off value or the IHVT needs soldered or replaced.

That's what I have seen...

Call your Samsung Authorized Service Center, they have the SUPPORT of Samsung to fix these faster

Samsung TXM3297HF shuts off after 2 or 3 seconds


Usually means your TV's lamp needs to be replaced. I'd need to know the sequence of blinking to really determine this.

Vertical deflection went out and now HV is going into shutdown


Hi,
Get service manual / schematics from HERE and find why vertical uotput IC is blown in your TV.
Service Manual will also give you info how to perform vertical adjustments.
Hope this info will help you to resolve problem.

Samsung ck-5339zb TV


only horizontal line it is a vertical section failure. caution keep brightnenn as low as possible till it is rectified & you put on tv before it this just to avoid screen burn. solution 1 check for loose contact or crack print or loose deflection coil connector. 2 check supply to vertical section. 3 check vertical ic. 4 vertical (50)Hz signalto vertical section. good luck

Hi, maybe just maybe something screwed in the yoke. Other than the vertical deflection coil, you may want to try to check the associated components. Sometimes they have diodes connected as a limiter/shunt. Again maybe... Pls post back, curious too. Good luck.
