Question about LG Flatron L1710S 17" LCD Monitor

1 Answer

Dead as a dodo.

When I power up the unit, the power switch illuminates (green) but nothing else. I've checked the (two) pcb's for obvious signs of damage but theye are pristine in appearance, all tracks in tact and no obvious signs of heat damage..

Does anyone have a service manual for this item, or perhaps details of voltage checks I can perform?

    Further to my original "Dead as a Dodo", I can't help negatively commenting on LG. I've been to their website and WASTED over an hour trying to actually locate someone to get information - don't bother you'll (like me) end up going around in circles and get absolutely nowhere - it's obvious they don't want to talk to you!

    In addition (I'm sure) that the LG service manuals have been produced to raise the blood pressure of any engineer trying to use same, E.g The Flatron 1710S (CL-42 chassis) I've been looking for, finally managed to download a service manual for same which turned out to be the LB700G-GD & GU and (guess what) power supplies are completely different - no surprise there! So manages to get hold of the 1710B (same CL-42 chassis) which (as it turns out) has the same power supply as installed within mine and guess what, NO SCHEMATIC for the power supply even though drawings exist for all the rest of the electronics - WHAT???

    I give up! How the heck are you supposed to service kit when the required information isn't available? For the amount of hassle I've had in just trying to get this (most basic) info, I've a good mind to throw this flaming monitor in the bin. What a waste of time - not impressed!

    Whew that's better - needed that!

ReCheck the connections.if the original power supply burnt out due to a short or system failure then you will need to check all the module boards for any evidence of burning.check the capacitors for signs of swelling or splits as these are usually the cause of no life.also I assume the power supply was the right volt/ amp as this May have blown an on board fuse on the main pcb.

No power on ricoh 3245c

Check your laser unit and in particular the polygon motor.

There is a small diode on the pcb that blows and it gives you a similar issue to the one your control panel is displaying. LCD dead and only green soft switch light displayed on control panel.

There is a RTB for this.

If the AC power source (outlet) is ok and the line cord and fuse are ok but the unit is completely dead, you may have a problem with the internal switching power supply.

Locate the switching power supply and see if there is a fuse on its circuit board.

Completely dead units are typically caused by a failure in the power supply section.

Please let me know if I can be of further assistance to you.

Good luck!
