Sony Trinitron KV-32XBR15

The picture has collapsed on the left and right Horizontal plane.
This problem produces an "Horu-Glass" picture/raster display.

I have checked for cold solder joints in the Horizontal and Flyback
transformer areas. I resoldered every suspected solder joint in these
areas but, the problem still exists. This is about all I can do since I donot have a schematic.

If the flyback transformer is bad, I would suspect a blank screen with no
raster. (?)

Any sugestions what could cause this problem?

Thanks,
Krist

You should check Pin-Amp stage for subject problem. Pin Amp is located at Horizontal area. Pin Out Transistor is suspected.

From your description it sounds like a yoke problem, you describe an hour glass picture which is a classic symptom of the horizontal sector of the yoke is at fault. The easiest way to test for this is a ringer tester, chances are it will show a short in the horizontal winding which causes the high voltage to load down and draw more current in the process.

Power on, sound no picture for three seconds, power off, led blinks 6 times pause repeat

  • Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.

That means no horizontal output which could be caused by a faulty driver stage or even a faulty power supply.
Hope that helps.

My sony trinitron 32" tv just went black and the

Hello

Six blinks of standby light in Sony TVs denotes the absence of horizontal oscillation.

No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.
In most cases the Ic is foud defective. anyway check its soldering points for any loose contact, or bad solerings. Check the line drive transformer, a very little transformer soldered directly to the main printed circuit board, very close to the horizontal output transistor. Check its primary winidngs for open. If it gets open no horizontal drive signal will be present at the base of the horizontal output transitor, that also may the cause of horizontal stop.

    Yes, you should check other parts. The horizontal output transistor is more than likely shorted. Also the flyback could have gone bad. Some SONYs have problems with the horizontal driver transformer which is connected to the base circuit of the horizontal output transistor. If this little transformer has a loose solder connection, it will take out the horizontal output transistor. This may give you some insight as to where to look for your problem. Stargazer
