Subject: [TechAssist] Philips 25F8 Chassis, Dead Set
This set exhibits some activity during turn on (pulse of voltage at =
outputs
of scan derived supply) but quickly shuts down. High voltage never comes =
up,
but the 130 volt supply at the Horiz Output Transistor is good.
We've replaced the vertical IC (with an OEM) because with that out of =
the
circuit, voltages all come up further and the degauss relay clicks, but =
that
didn't solve anything. Resistors and diodes in vertical section all =
check
OK.
There is a manual in the download area, but the troubleshooting =
flowchart
pages are clipped off on the left side.
Does anyone have a suggestion for this one, or readable troubleshooting
flowcharts?
Thanks, Art.
