Where are tha capacitors fo misubishi wd62725 located

1. If you haven't done so already... Unlplug the TV!
2. Remove the rear lower outside panel using a phillips screw driver. Set the panel aside somewhere where it won't get tripped over and broken.
3. Remove the screws from the lower metal panel that hides the electronics and connections. When removing this panel from the back of the TV, there will be an exhaust fan attached. You will need to disconnect the fan's connector in order to set it aside to get it out of the way. Take note that all the connectors inside the TV except for one on mine had the ends labeled with a code so that they could be matched up when it comes time to plug things back in. Just make sure that when you're disconnecting the connectors that you number them or code them if they aren't already marked as there are probably 10+ connectors that will need to be undone in order to get the electrical chassis out.
4. Remove the big metal plate on the left side of the electronics chassis. This will help you get the electronics chassis out of the TV.
5. Slide the TVs power cable up and out of the slot that holds it in place. This will also give you slack to move the electronics chassis out of the TV so you can work on it.
6. Unplug the USB and Firewire connectors from the top of the electronics chassis.
7. Carefully slide the electronics chassis away from the TV. Take note that you will have to start to disconnecting connections now in order to get the chassis out of the TV, I didn't fully remove mine from the TV. There were just too many connections that needed to be undone. So what I did was undo enough of them so that I could set it on a chair, but still connected to the TV.
8. Now the electronics chassis is out so we can work on it. Remove the protective metal housing from the electronics chassis and expose the circuit boards.
9. Now you should be able to see your circuit boards. There are typically two boards that have bad capacitors on them. One is called the DM board and the other the Power board. The DM is the hard one to get to as its the middle board of three. When accessing this board, be extremely careful of the ribbon cables at the bottom and sides of the boards. They can easily be broken, torn, etc... Again, take note of the connections you have to remove and make sure they're labeled. Take a picture of things if you need too.
10. Now that you can see the capacitors on the DM Board, look for a grouping of capacitors:
11. Now look at the Power board. Its the board on the back of the electronics chassis. There are two capacitors to look for here: Photo of Power Board Capacitors Are these bulging or leaking? If so, they'll need to be replaced. Look for others while you're here. I ordered mine from mouser using this part#: Mouser Power Board Capacitors Link
12. Once you have the capacitors replaced. Button everything back up and hope for the best.

How do I disassemble a crt lense assy in proj tv? I have spider webs and bugs in all 3 assyd of my rear proj tv...

You will need to pull the complete crt assembly one at a time, Drain the coolant then remove the screws that secure the lens to the crt. But then you will need to replace the coolant. Do not try to loosen the lens while still in the TV or the CRT coolant will leak onto the chassis which can destroy the Chassis. You can get a CRT coolant kit at which will contain the coolant and the Instructions.

Flashing green timer light

The Chassis Assembly will need to be sent to Mitsubishi for them to refurb. I would estimate the cost to be 850.00 to 900.00. A Authorizes Service Facility would have to confirm this.
Hope this helps.

Screen is getting darker

The most likely cause is the blue and green tubes need to have the cooling fluid changed. After many years the blue and green get clouded with algae. The red tube won't have the problem due to the red spectrum kills the algae before it has time to grow. 

The way to replace the fluid for is to completely remove each CRT from the set, remove the drain plug, drain the fluid out the tube, disassemble the lens, give it a good cleaning; then reassemble; add fluid; and reinstall in set. If you check with the site they are working on a kit that includes the fluid and photo instruction guide.

Wd52725 cap replacement

The power pwb is on the opposite end of the chassis opposite the Input locations. I believe on tha model the plu assembly gets removed from the case and stays with the chassis block. I believe CN1 and CN2 are the ballast connections you need to remove a metal shield on the ballast Circuit to see the connections.

DM removal

You will need to remove the entire chassis block as outlined in the manual. DM stands for digital board. It will be listed in the manual as PWB DM its sandwhiched in between other boards inside the chassis . Which is actually a metal box that will need to be disassembled then each board removed to get the DM . The DM is usually the bottom board. I dont have access to the WD65833 sertvice manual, but I am famillar with it. The DLPs are all simallar the entire Chassis block needs to be removed. Hope this helps if you need more info, let me know.
