SOURCE: sony bravia kdl 32l4000 - color bars running vertically on screen

In most cases is the screen is covered with vertical lines all the way accross the screen then the T-Con module is at fault. The t-con board is replaceable without having to replace the entire LCD panel which would usually make it cheaper than replacing the TV. The part number I come up with is 1-857-213-11. Please take a moment to rate my answer. Thanks...

SOURCE: I have a 42JC2D TV. Vertical color bar lines

Hi,
It is hardware issue related to LCD Panel (screen).
Regarding fixing it, it depends if you are handy with electronics stuff repair and can replace circuit boards in tv etc then please check T-Con (lcd controller board) on top center position at rear of lcd panel, this board would be covered with metal shield. Need to take off back cover of tv to get access to T-Con board. If T-Con board does not solve lines problem of screen then LCD Panel is bad and will be replaced.
If you fee uncomfortable doing so then repairman option is better choice.
Hope this info will help you.
Thanks.

My tv keeps switching off after about 20 minutes after initial starting. if tv is switched on immediately, then it works for less than 5 minutes before switching off. model: power vision.


I do not knowtis make , but this type of fault is sometimes due to dry joints in the flyback circuit or power supply try resoldering all pins on flyback transformer and chopper transformer, also cheek that the ht voltage is as the makers state. Waring unplug from mains before removing back and discharge ht resiour capacitor before starting repair

Could I possibly have a bad flyback transformer


I would try resoldering the flyback connections on the Circuit board. if the flyback was defective it would operate and you usually get 3 blinks on the LED indicator. Sounds more like a solder issue.

with your new flyback transformer ther should have had a resistor and cap in the kit.if you look at the fly back from the rear ,on the right side very close to the transformer.and on the other side 3 resistors one has changed value about 38k-ohm.

It won't turn on


The smell of something burning is not a good sign. The clicking sound you are hearing could be a relay or breaker kicking in and out as a result of whatever is wrong.

This could be cause by:
1. A problem in the power supply.
2. A problem with the Horizontal Output Stage.
3. The Flyback transformer.

Someone gave me a TV once that had the same problem. I determined that it had a bad flyback transformer. I replaced the transformer and the TV worked about 5 secs before I saw some black smoke come out of the new flyback. I turned it off right away and realized that something else was bad that caused the original flyback to burn up. The same thing was causing the new flyback to go as well. It turned out to be a shorted, 50 cent hi-speed switching diode. Fortunately, because I had turned the set off quickly when the 2nd flyback started to smoke, once I replaced the diode, the TV was fixed.

If you want to get it working again, you'll need to have it serviced.

Good luck,
- Jim

you need to replace chemical type fuse marked FL231 part number 259213, it`s located next to the flyback transformer, theres 3 of them there but 231 is the only one I`ve seen cause your problem, replace it and you`ll be all set.Happy Holidays !

Hello paulaspec,

You have a problem with the three factors, and they are screen voltage, focus voltage, and control (focus 2) voltage. Basically these voltages have to be adjusted since the components in this section have aged some. These controls are usually located in the television on the IHVT (Integrated High Voltage Transformer) or as it is also called the flyback transformer. these controls must be adjusted together, along with the color controls. Here is how the adjustment is done (You will need a schematic diagram, a DC volt meter, and a color bar generator to do these measurments):

 

1) turn color and tint fully counter clockwise until you have a black and white picture.

 

2) connect the color bar generator to the TV (ch 3) and turn it on, you should see bars in various shades of gray

 

3) adjust as best as possible the color and tint controls to obtain the color bars on the screen Red Green Blue.

 

4) measure the voltages on the focus, screen and control grids of the CRT and match them to the schematic digram measurements.

 

5) adjust the focus screen and control grids to match the ones on the schematic diagram

 

6) once this is done then you adjust the color controls once again to obtain the red green and blue bars on the TV screen.

 

This should help if the CRT (picture tube) electron guns are still good and if the flyback transformer voltage supply is working.

 

However if you do not have a background in electronics please take the TV to a shop for repairs.

 

I hope this helps,

Thank you,

You have the famous regulator problem, or the bad regulator problem, or the cold solder connectioin is on or around the flyback transformer.
