Ok, 4 means Vert failure, 7 means.....what?
My experience has been the vert failure can actually show you the Horiz/IHVT
is the problem since it supplies the power to the Vert ciruit.
And 7 means the Horiz Deflection has stopped......
Don't look for shorted Horiz parts, look for something that will stop the
Horiz signal from being created.
Video Jungle, 9 V supply, Horiz osc, bad connects from jungle to the H
driver.....

> Customer said the set would sometimes not start up, so he left it on 24/7
and worked fine. About 2 month ago, when he was in, I told him "with price
of electricity" may be cheaper to have it fixed in the long run. Not sure
about that now.;-)
> Problem with the "flashing" fault indicator, sometimes it will flah in
series of 7, and if I turn it off, and back on, will flash series of 4.
According to Bob Waterman and others, this "flashing" is not always a true
indicatior.
> When I power up, set makes a rattling sound, but I believe this is a
modification on the degausing coil. Not concerned about that.
> I hear a relay click on, then off. After about 5 seconds, I hear another
Relay click, then standby light will flash either 4 or 7 times.

> Sorry...not much to go on, H/O transistor is not shorted, so if anyone has
any tips for caps in Regulator, or other fixes along this line would be
appreciated.

> I have the manual,but apparently not the experience on this one. Plus I'm
working at Floor Level, which doesn't make it any easier. Thing weighs a
ton, and have had no help getting it up on the bench. Some of you older
techs can probably relate to this.....Have you ever noticed all our "circle"
of friends seem to have Heart or Back trouble. They can lift that cup of
coffee, but anything over 20 pounds creates problems.;-)
