Need to know how the front screen comes off - Hitachi 53SBX59B 53" Rear Projection Television

ONLY 1 of 2 things can cause this problem----

First thing to do is remove front speaker grill--it should pull out and issecured with plastic pegs--behind it you will find an inspection plate---

Notice the one or two pairs of wires coming from the front keyboard of theset---remove the inspection plate and follow the wires to the right--you canunplug both plugs(most have two and they are marked with letters and differents so you cannot get them wrong)

The idea here is to remove the front keyboard with its reset button etc fromthe circuit---You will still be able to try to turn the set on with theremote---

These sets have a Receiver that is called a DM board--(large metal box to theleft as you look from the back) and if the power goes out the green light willblink for about 70 seconds and then go out---it is the Receiver booting up. Itis called the DM board.

If disconnecting the keyboard allows the set to turn on--you have a bad resetswitch and two choices---either operate the set only with the remote or toremove the front screen and get at the reset switch (it is tiny) and removeand/or replace it.

If disconnecting the keyboard does not restore the set to operation---thereceiver is bad---there are 4 or more caps and some pico fuses that can fail inthat unit---Mitsubishi no longer sells or repairs these--if it is bad and notthe caps there is a company you can send the unit to and have it repaired--ifyou need to know their name let me know---

You can call them and get a quote for repairing the receiver.


Let me know what more information you need--I am here to help.

bdawk20mvp,

You can get a new screen at http://www.encompass.com. You need to know that the screens come in three parts and you probably need all three. I have a tip at

http://www.fixya.com/support/r6210638-replace_broken_projection_tv_screen

which you will need to get the correct screens and to disassemble and reassemble the unit.

Thanks for using FixYa and for the great rating.

Is the the spanned wrench located on the screen in the lower left? if so touch it the screen will change then open and close the front door the code should go away, if the code comes back need to know what it is,

Yes, front screen can be removed to clean projection mirror and picture tubes lenses.
Remove speaker grille, pull them to remove.
There are 3 screws at bottom of front screen, remove them. There are few wire harness plugs need to be disconnect to remove completely front screen.
Below exploded view of Mitsubishi VS-50607 will help you to remove front screen to clean inside. Be careful while removing screen.

pop the front strip under frnt of screen off. remove screws around back edge off screen and under the frnt of th screen. Usa a micro fiber cloth to clen screen.

it should just come out with a nice firm, but gentle pull. problem is u need to be careful because if its that clogged up, its probably weak and might break. U can always just buy new ones at sears, or home depot.

I think that the solution that you are seeking is on page 63 of the manual.

the dmd chip board (which holds the splash screen) need replacement. also, if you remove the top, use a plastic knife and push the back of the main board from the bach towards the front to reseat the connector.

you need to have the lcd replaced

you have to take off the speaker grill on the front... it just pops off, it's a little unnerving yanking on it but it will come off with a little force. Then there are similar screws on the front of it.
