Help with Loewe TV

[Don Goulding]

Hi All,
I need help in fixing a Loewe Arcada 84 cm 100Hz tv. Not too sure what
chassis it is but the sales docket says it is a Media Plus Q2500.
A violent storm went through our suburb and I'm not sure if it has spiked
the set even though it wasn't on - not even in the standby mode.
The set is about 4 years old.
On switching on the set, the red standby led is lit and the green "on" led
keeps flashing. When pressing the " power on" button on the remote you can
hear the start relay in the set operate and then release. The set then
starts hiccupping with both leds flashing.
The diodes and Fets in the secondary side of the P/supply test out OK and
so do the diodes and the main transistor in the horz. output stage. (no dead
shorts)
The 8 volt and 9 volt rail (7808 &7809) on the output I am reading about 124
ohms to ground. Is this normal?
Any help will be greatly appreciated.

Thanks in advance for any help.

Don.

Try posting this on sci.electronics.repair, there are some pretty good
tech's that trawl through there.

From memory there is a power supply kit availiable for that chassis, try
contacting International Dynamics in Melbourne.

Loewe sets normally come with a schematic if thats any help.
I've got one but it's for a 2300 or 2400 earlier model.

Someone in aus.audio-visual.home-cinema or aus.dvd might be able to
send / fax you a copy if you don't already have one.
