DIYbanter - Tale of a monitor

Hi Paul

End of saga: the fault was High Voltage leakage from the top
Backlight to chassis.
It finally dawned on me, that the reason why, with the
Inverter PCB only running and remote from chassis,the
Backlights stayed on. But as soon as you reassembled
everything, you were back where you started. I lost count
how many times I did this. (blame getting old).
Proved the point by running inverter remotely and when lamps
were running OK, shorting the Inverter chassis to LCD
chassis, tripped Backlights off.
That's when I started my real troubles.
To get at lamps, you have to dismantle Panel: not an
impossible job, but remembering how everything is fitted IS.
Get it right and it is passable. But I got them Muddled a
few times.
Re Broken Backlight I got a quote of £38.00 for a similar
light and the dealer had to order from America. I declined
quote as description pointed to the possibility it was not
an exact replacement.
Have wired in a Laptop lamp protem to carry on testing, but
I think its throwing the error circuits out of balance.

All above is in material now. ON the last assemble, I must
have damaged the LCD screen as I now have about 3" of
vertical coloured lines on Right Hand side.
So I think Monitor is a write off without I can get a
reasonably priced LCD module.

There was one offered in Italy, but with carriage charges it
was nearly price of new Monitor.

Regards to both of you, and hope you are getting settled in OK.
