My Ultravision TV is now having horizontal lines. Do not know if it has a horizontal hold button hidden somewhere or is the TV going out? Can I fix it myself. Large screen


Can you try and see if it is your source that has the lines or the actuall TV that has the horizontal lines.
What is your source? Direct TV, Cable TV or even off air Digital TV.
If you remove your source do you still get the horizontal lines? If you do then what colors are they? Seems if when you remove your source input and you still have these H-lines then you have issues with your individual LCD palets. Especially if they are just Green, Red or Blue?

The horizontal hold


If model number correct (the one posted here) set does not have a horizontal (rolls left to right) or a vertical (rolls top to bottom) control.

Verify model and brand so I may offer some suggestions

I have a WS 65908........it has the same problum--listed on this site.......power on for 3 seconds...and it said this.... Do the self test this model has: When set shuts off and on front of set power...


Error code 23 on this set means that the Horizontal Deflection circuit of the set has failed. Usually this points to a damaged Horizontal Deflection IC and sometimes the HOT(Horiziontal Output Transistor) as well, not to mention the resistors that are blown when the IC failed. Replacing these parts should resolve the problem.
PS:Note that the Deflection circuit involves certain high-voltage components and prior to repair it is advisable to discharge the high voltage before attempting the repair. You will also need to know how to use a multimeter(to test the HOT and look for blown resistors) and a soldering gun. If you think you can do it yourself, let me know and I will provide you detailed step by step instructions.

Horn and power seats quit working. maxi-fuse extremely hot. pulled it out and re-inserted after it cooled down. fixed the problem temporarily (a day or so). swapped that maxi-fuse with the one above it...


which maxi fuse gets hot ? # fuse , plus amps The power seats uses a 30 amp circuit breaker ,not a fuse . The horn gets power from the same circuit breaker . . Sounds like something is drawing to much current. Do you know how to use a amp meter to test current flow . Disconnect componets till draw goes away ? How to use a wiring diagram to pin point areas in a circuit to test ?
Is there corrosion on the pins where the seat circuit breaker plugs into ? Reach under your seats an see if one of the seat motors is hot .

The left and the right power seat system consist of the following components:
• The seat switches
• The seat relay modules
• The 4 reversible motors:
- The front vertical motor
- The rear vertical motor
- The horizontal motor
- The recline motor
These 4 motors operate independently of each other.
When the entire seat switch is pushed to the FORWARD position, the forward input of the of the seat relay is grounded.
The seat relay module supplies battery positive voltage (B+) with a ground to the horizontal motor, in response to this input. In order to drive the seat forward, the motor runs until the switch is released.
The BACK position works similar to the FORWARD position with the exception that the voltage polarity supplied by the seat relay module is reversed causing the motor to run in the opposite direction. This action drives the seat backward.
These recline switches operate similar but independently:

The seat relay module could be bad , If you don't know how to do automotive electrical circuit testing it mite be a good idea for you to take your vehicle to a qualified repair shop.
Could have diagnostic trouble codes stored as well .

Ps 27123 have sound, tuning etc only small horizontal color band


Hello bdedrick708,

If what you are trying to say is that you have a 1/4 inch horizontal line across your screen, this means that something in your vertical deflection circuit has failed. This could be the vertical oscillator, the vertical output processor, the vertical coupling capacitor, or the vertical section of the yoke transformer.

If what you are talking about is a vertical line from top to bottom then you are possibly talking about a failed horizontal section of the yoke transformer.

Why so little about the horizontal section of the yoke? That is because if the horizontal section fails completely then you would lose high voltage and no line would be present because you would not have raster (screen light).

In any even check the yoke transformer first. Then work back from there.

I hope this helps,

Thank you,

Shuttle83

Horizontal white lines across top of TV screen


Vertical hold circuit is failing.

Check capicitor in vertical hold circuit. You should have solid knowledge of electronics repair before attemping repair. TV's can emmit harmful radiation, and produce voltages up to or in excess of 30kV.

Horizontal hold?


possible bad solder connections at the horizontal drive transformer connections, could also be a bad capacitor in the horizontal circuit look for Capacitors that are bulged or show signs of leakage.

Horizontal output transistor keeps failing


The horizontal output transitor is always connected to the primary winding of the flyback transformer (via collector) and also to the horizontal deflection coil via an electrolytic capacitor. The most likely suspect for damaging the transistor is the fylback transformer. In some countries there are electronic stores that test flyback transformer by winding a few turns on the ferrite core and applying a test voltage. This test will only test the secondary. The primary winding is difficult to test for turn to turn short because the resistance is quite low and you do not know the 'good' resistance.
