Listen for the colorwheel noise
you'll recall hearing it "wind up" as the tv came on
many of these will go bad and then it will never fire the lamp because the colorwheel doesn't get up to speed

if you don't hear it, suspect the wheel, its hard to get since toshiba never had it as a seperate part

if you do hear it, its probably a bad lamp driver, but unlikely

let the tv go and go, it will try like 7 or 8 times and then eventually spit out an error. your user manual has the error codes, it will tell you if its the colorwheel i belive.

let me know if you need further assistance

Toshiba 56hm66, lamp replaced but lights still blink


Check the circuit boards to see if any have failed. They are small cylindrical objects. If the tops of any of these are bulged instead of flat then they are bad and board will have to be replaced. Hope this helps.

Installed new lamp. When powered up blue solid light and yellow blinking light (15x) , tv would torn off and on several times trying to light lamp. Once that failed red blinking light and yellow solid...


Hi Genaro,

Blue led light lit solid and yellow led light flashes is an initial attempt of the set to re-light the lamp.Red led flashes and yellow led light solid means that the lamp won't light up that's why it only has sound without the picture.
Since you've replaced the lamp twice and still the symptoms persist, I suspected that the fault came from the ballast board and not on the lamp itself. If the ballast board gone to malfunction, there's no high voltage will produce to light up the lamp and will sensed by the processor and trigger the error code (Flashes/solid led light with color code).

To verify whether the ballast board is faulty or not, check if the lamp will lit by looking through the lamp door louvers at the rear of the cabinet upon turning on the set.
Please let me know what you will find to assist you further.

Unfortunately lamps go bad without the visible state of being bad. I don't know who or where you bought the lamp from but I order all my lamps through dlplamps.com
The clicking sound you hear is the lamp inverter igniteing the lamp but the lamp is bad.

No picture on my samsung 61" dlp.


The color wheel if bad enough, will cause the lamp not to light. If the lamp is truly bad, you can't usually tell by just looking at it unless of course it is broken.

TV makes humming noise, lamp light is blinking, does not turn on


Your color wheel needs to be changed. Mine just did the same thing. I changed mine, and the buzzing sound went away, however now my picture washes out with light or yellow colors. The darks look green and purple also.

TV doesn't turn on


You really should give make & model number when posting, it helps us immensely, your lamp and possibly the ballast is bad, start with a new lamp first, odds are very good that it will fix your problem, can`t help more without manufacturer and model number, good luck, ps, order the original lamp, generics are junk and a waste of your money.

No picture or sound after replacing lamp


Possible bad color wheel...

Pull the lamp out & look inside where the lamp sends the light-

does the color wheel look defective? If so,replace it.

Or, the lamp ballast may be bad.After that,usually replace

complete engine.

Tv keeps turning off?


cutta, you will most often hear a click on boot then the fans start up and lamp will then fire. The picture will start to show up....at what point does it shut off? and do you hear a click when the tv is turning off? Is it the complete tv shutting down, fans and everything that turns off? Do you see any lights on the the front panel "POWER", "STATUS" or "LAMP", what are they doing? If you see a Power, Status or Lamp light after it shuts off the below are what they mean if there is an issue. POWER - STATUS - LAMP - CONDITION/ISSUE: Off - Yellow - Off - Temp. high/dirty filter/excess room temp Off - Off - Yellow - 4000 hrs. Lamp usage warning Off - Off - Blink Yellow - Lamp Cover open Off - Blink Yellow - Off - Air Filter Cover open Off - Off - Red - Lamp failure (failed to turn On or broken) Off - Blink Red - Off - Fan Has Stopped Off - Red - Off - Circuit failure (short) or DVI cable disconnected If you want to check for the last "Error Code", after you first turn the TV on, by pressing the front panel ?DEVICE? and ?MENU? buttons at the same time and holding them for 5 seconds, it activates the Error Code Mode. The ?Power LED Light? blinks/flashes (1/2 sec delay) and then flashes again denoting a two digit Error Code indicating no problem or an error has occured since the last Initalization. i.e. "Power light" blinks 3 times (1/2 second delay) and then blinks 4 times then 1 sec delay and repeats a few times. This would mean "Error 34 - Lamp abnormality". See below for error codes..... Error Code - Description or issue 12 - No Error detected, check Power Supply 32 - Lamp Cover is open 33 - Air Filter Cover is open 34 - Lamp abnormality 36 - Light Engine (DMD or LAMP Fan stopped) 37 - Exhaust or Lamp Ballast Fan stopped 38 - Lamp temperature high 39 - DMD temperature high 41 - Short is detected 44 - DVI cable between FMT & Engine disconnected. Sorry for the long answer but it was an open ended question.
