    HV Block notes:

    1) Remove light box from TV

    2) Flip up PCB on CRT (front) side

    3) Locate HV block

    4) Unplug 4 or 5 ground wires,push aside

    5) Notice how RGB, input and focus wires are labeled and

    where they plug in----make notes...release /unplug wires..

    6) Make a hook from paper clip to retrieve rubber guide sleeve,

    one for each wire,four the same size,one slightly longer for

    focus lead....

    7) dis-mount old block....mount new block ( discard new plastic

    lock sleeves--originals work just fine....

    8) Make sure each wire has rubber guide sleeve...

    9) Re-install all wires as they were before--

    10) Fire it up!!!! Hopefully,you are done--if not-------

    Unplug RGB wires one at atime to see which CRT is bad!

    Please let me know.........T.

    originals work just fine...

Seems that your television core was burned out.
If so, you'll have to change the core entirely, or it might be (in most cases) just the power supply inside the television.
Ask te shop you bought it from, they'll change it for free if you have warranty. If not, you'll be required to buy a new power supply, which costs around $50.
How long have you sed this television for?

Lamps keep going out. 4 since 2006


This is happening because the "Root Cause" is NOT being fixed, the "Lamp: is a SYMPTOM, NOT the "Cause". Replacing the Lamp is just spending good money after bad....Unfortunately there are quite a "Few" causes for it. If it has been done "Professionally" then they HAVEN''T done their job properly.

My Mitsubishi DLP wd-57731 has a green hue in dark scenes where there is little light. I replaced the bulb about 4 to 5 months ago. What could be the cause? Thanks.


It sounds like you might need a new light engine, make sure the lamp is the original replacement, if it is then you are in for major and pricey repair, close to $1000 good luck, Julio at Millenium TV (702) 736-1091 [email protected]

I have a mitsubishi WD-57731 57 In. DLP. When I power it up I get no or video it makes a whirring light clicking electrical sound in the back. The timer indicator flashes green for like 20 secs or so when...


The whirring is the fan. The clicking is the spark gap on the ballast releasing the unspent voltage trying to fire on your lamp.

Check your lamp; it may be unseated (unlikely) or just blown/bad (likely).

Screen going dark


Definitely. The lamp often looses oomph before it goes. Think about how long you have had your set. The average life seems to be around 2 years. Eventually your set will indicate the lamp needs replacing, if it hasn't already. I see your posting is about 6 months ago. Are you willing to verify for everyone else?

Wd57731 won't power up


Have you checked the air filter? Did the set operate normally after replacing the lamp?

Mitsubishi wd 57731 wont power up


There is a lamp cover on the back that only requires a few screws to remove. the lamp is behine there, you will need a standard screwdriver to remove the lamp and inspect it. If indeed the lamp is bad you will see it shattered and/or burned at the tip. The timer light flashing for 30 seconds is normal as the TV is going thorugh a boot up process. One word of advise, don't touch the glass part of the lamp pnly the case.
