To open the case of DELL 2405FPW (and 2407FPW and many others): first prepare a clean, clear area of bench to work on. A cluttered bench could result in damage to the screen when you lay it flat on its front!
a) unclip the panel from its stand and remove the four screws in the center that usually hide behind the VESA Mount.
b) stand the panel upright on the bench on its bottom edge. Using your fingertips prize the front bezel (plastic frame) forward from the glass, but without putting excessive pressure on the glass. It should come away with a series of 'snaps' as it releases from the back section of the plastic case. Proceed all the way around the screen detaching the bezel from the back. You do not need to completely remove the front bezel as it is connected at the bottom with a ribbon cable to carry the signals for the buttons and LEDs and this cable must not be stressed.
c) The back section of the case, together with the silver portion (which is screwed to it) can now be completely removed and the panel laid face down on the bench, resting in its bezel. Do not lose the little mounting release button which is now free too fall out of the back of the Vesa mounting in the case!
d) Now we see all the metal covers hiding the various subsystems of the monitor. With the bottom of the screen towards you on the bench, the driver for the backlight is readily accessed by removing the four screws holding down the shiny cover on the left. But I wasn't after that.
e) to access the power supply and system board you first have to remove the shiny cover over the memory card reader/USB hub on the right. Remove the single screw on the top left of it. While gently lifting the two little clips at the extreme right-hand edge, slide the shiny cover to the right to release it from the main panel chassis.
f) Now you should be able to access all six screws holding the central metal cover on. Remove the screws and simply lift the cover upwards to expose the PSU and system boards.
g) To remove the power supply board: Note the position of the little black plastic clip retaining the power inlet connector before removing it. Disconnect the two multi-way cable looms from the system board (right) and backlight inverter board (left, top). NOTE: The looms do NOT detach from the power supply board! Remove the three screws from the corners of the power supply board (note these are the ones with very broad heads) and the big shiny screw tying the protective earth lead to the chassis. The PCB is now only held in place with a little white plastic clincher near the middle which needs both sides to be squeezed before the board can be lifted clear.

My particular monitor had a failed POWER SUPPLY board. To see how you can fix it if you had the same problem as me, I have a full account here on Fixya: "Repair of DELL 2405FPW"

Hope this helps!

I opened up an LCD by removing any screws you see on the backside and any that may be hiding under rubber buttons or stickers. Gently pry apart the frame from one side, center. Youll find out that the frame is clipped onto the rear part by integrated clips and youll ba able to see if you need inward pressure on the frame or base to unclip the frame portion. It is a "nervous time" procedure but the plastic is pretty tough and its not doing you any good as it sits, right? The power supply had one fuse and had the inverter intregrated into it. Mine was fine, but an SMT MOSFET component on the driver board was completely blown apart from voltage spike. Salvaged LCD and tossed.

How do I start my tomtom 2405. It has been sitting for 1 year. Charged overnight. The start button is green

Have you tried to RESET it ? .... either, hold down the power ON/OFF button for a long while ... (e.g. 30 seconds or more) ... until the device starts up (then let go)..... or use a pin (paper clip) to push into the RESET hole at the bottom of the device.

My TV won't turn on (42pf9630a/37)

I'm soory to hear that atombomb72.
If you are able to open the back cover and check the fuses inside the power supply for open conditions.
The problem more likely be a defective power supply or a Ysus board assembly.

I see so many here with no sound/nopicture issues:


1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.5_26_2012_3_06_42_pm.jpg5_26_2012_3_07_32_pm.jpg

I have samsung(hitron) tv purchased around 4 years before. When the external power supply(switch) to tv is switched on, tv is not receiving any power. i mean tv is not functioning. what would be the...

Give me the model number for more accurate diagnoses....
It seems as though there is a DC problem on the power supply, it could be a simple fuse. Or it could be that a fault on another board is causing the power supply to shut its self down.....The TV is in self protect mode because of a short an open component somewhere. Like I said it could be just a fuse has blown. If the indicator light is on then its probably not a fuse problem, but rather an electrical fault.

Nad c350 no power at all

Solution if all fuses checked out OK and +/-40V are present on main PCB DC connector from power supply:
Check for +37V and -37V on small sub-power supply PCB - mounted vertically on the main power supply PCB. (next to ribbon cable connector is a layout with voltages.) If the +/-37V are missing check (replace) C501 (0.1uF) on the small power supply PCB for leakage, but also check (replace) R401 (2R2) and R402 (2R2) on the main power supply PCB. Both resistors are fuse-resistors and will have gone open circuit when C501 has gone leaky.
