Question about Televison & Video
Sometimes you can get picture w/sound, then, a few seconds later the screen goes black. Still have sound. Any suggestions what is happening?
Sounds like the tubes are blanking due ti vertical output. Try resoldering the vertical output IC and see if that corrects the problem. If not chances are the HV splitter or Flyback is bad. And in answer to your question. PTS corp may possibly have the board or at the very least they can rebuild yours. here is a link to PTS. Try soldering the Vertical first. if you need to know how to check the HV splitter let me know. If all else fails call pts's toll free number to see about a rebuilt Circuit board. Hope this helps.

With the indulgence of sweet_rascal, salt56 and robotek...
The coolant leak and/or the horizontal/HV problem are on track. However, if for some reason problem persist, may I offer alternative area to focus on?
It is also possible for the vertical IC to go bad. Either that or a diode across 2 of the pins of the same IC. Indications would be excessive heating of the IC.
Hope this be of additional/alternate help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.

Hi Imoden, does this problem occur all the time, or just once in a while?
