Re: Planar PL2010M-BK -Black screen

Well with the Proper power supply , I now get a solid green light when hooked up to a PC .. but still noting on the screen .. Is there a way to test the lights in the panel it self ?

Re: Planar PL2010M-BK -Black screen

Ok its a 10 volt 100 uf cap .. I still get no screen .. the green light stays on now .. is there any way to test the back light tubes .. to see if they are burnt out ?

Hi...
"with the Proper power supply" what do you mean with this?
"Is there a way to test the lights in the panel it self ?" another monitor/inverter or other known good lamps.. or the trick of disabling the protection temporarily..
about your supposed bad cap i saw the board on sale's picture, if you mean the black cap put on its side that under it is only normal glue.

The Proper Poser supply I mean .. the original was not given to me .. so I used a 12 volt 2 amp one .. I got the proper one now .. a 12 volt 6.6 amp

Replacing the * 2 bad caps on the board the power does now make the green light light up , and it stays green when hooked to a PC .. but turns orange after a bit when not .. So I know the monitor is getting a signal and knows it . I just do not get any screen to come up .. I have tried the " 2 finger " Reset but does not help .

With the other power supply I would not get a green light , until I replaced the capacitors , but after replacement , I would get a green light that went orange soon , even with the PC on . So the lack of proper amps must have caused that .

* The 2 bad caps were in align with a third that did not blow its top , Do I need to change that one out too ?
Also do I need to check Fuse's after they are removed ? as all appear OK while on the board .

Thank you again for any help ..

Re: Planar PL2010M-BK -Black screen

"the original was not given to me .. " So i guess that is an external one..(??)
"So the lack of proper amps must have caused that" Let me understood.. with the original and with the other psu is the led behavior the same (first green then orange..)?
"Do I need to change that one out too?" there's no picture of psu or board where psu goes .. no schematic, so i can't tell this..
"Also do I need to check Fuse's after they are removed ?" No.

Re: Planar PL2010M-BK -Black screen

.. The monitor acted different with the 2 different power supplies .
The one that came with it was no longer putting out power so the guy tossed it after I bought a new one . The one I tested it with was one I had that was lower on amps then what the original had .



That is the Power board .. The red circle is where I replaced 2 of the three.
470 uf 10 volt .. I only had 470 uf 25 volt available to use.
the under side of the board shows that they were all connected parallel .

Here is the Video board .



When I bent the dark one in the corner up to read it's size . the leads broke .
I can put a 25 volt 100 uf in its place . it was by reading the part number and going to the manufacturer web site it was a 10 volt 100 uf .

If the Panel is dead I am not going to put anymore money into it . ( the guy does not want the monitor now , so If I can't fix it I am out the $'s the new external power supply cost me )

How can I check to see if the panel it self will light up ?

Thanks ,

Re: Planar PL2010M-BK -Black screen

Well fuses are all ok .. a few other caps dont seem to hold steady when I check with ohms on meter.
I wonder if the CF tubes are broken or non functional .. any way to test ?

Re: Planar PL2010M-BK -Black screen

Which fuses are ok - the two on the inverter board?

[K_K3N]

Re: Planar PL2010M-BK -Black screen

the 6 on the board the power plugs into

The monitor power light stays green when I hook up to a system as a second monitor .. Win 7 even recognizes it .. if I disable it , the power light goes amber .. as expected

Re: Planar PL2010M-BK -Black screen

Six fuses? This unit has six lamps so even one or two are broken, at least you should see the working lamps flash on for seconds before the inverter goes into protection mode.
We need the straight shot pictures of the inverter board top side and bottom side, the pictures must be clear enough to see traces on the traces.

Re: Planar PL2010M-BK -Black screen

Can we have good clear pictures of your boards posted using manage attachments
not posted off site.
They need to be like the original posters so we can see what you are talking about.
Mark up the board with the six fuses you have tested.

The problem you are having probably relates to fuses on the inverter board I think I see 1 fuse - its pretty blurred the original poster has 2 so please check They will be labelled F1 and F2 in all probability

Re: Planar PL2010M-BK -Black screen

Here are the Fuses I checked .. FB1 thru FB6

Re: Planar PL2010M-BK -Black screen

FB = Ferrite Bead (it's basically a very small inductor), they are not fuses.

I hope these are clear enough ..And Thank you for help

Re: Planar PL2010M-BK -Black screen

OK, check and report the DC Voltage readings at both ends of these two fuses which feed the B+ to the inverter transformers drive circuits.

[K_K3N]

Re: Planar PL2010M-BK -Black screen

I got voltage on one end of both fuse's and none on the other with unit plugged in

2.0 = .. 2 amp fuses?

Re: Planar PL2010M-BK -Black screen

They should have 12VDC at both ends of the both fuses, so it means that those 4 SMD POWER MOSFETs (8-leg SMD) above those two fuses may be shorted out that caused the fuses to blow. We will need the P/N as printed on top of those 4 devices.

Ok I get the numbers I did have 3 bad Caps I replaced could that have blown the fuses ?
