Hi,
I have a Magnavox (Funai) TV/DVD model CD13OMW8 in my service
shop (no service manual) that won't power up. Power supply, H.O.T.,
horiz. driver transformer, horiz. driver transistor, etc. have been tested.
There is no H sweep signal (scoped) at the horizontal driver's Base when
the power button is pressed. Note: There is a response to the power button
press such as increase in AC current, regulated B+ increase for "run" mode,
but only briefly due to horizontal sweep not "running".
Since this is a 13" TV (with DVD player), I did not want to spend too much
time on this job.
I suspect that the missing horizontal sweep signal for the driver is
due to a defective "jungle" IC, but I did not circuit trace back to
the source due to additional time involved.
Anyone have the exact same problem with this model?
Thank You in advance, John
