SOURCE: 52HM84 Toshiba DLP with apparent failed lamp (replaced ballast)

I found R3 on the original board to be open, along with reading an open on CR1, D5 and D6. All the other transistors and the transformer check out. The only thing I have to do now is find out the specs of the diodes. The replacement board also had CR1, D5 and D6 open (R3 was OK). There had been some threads on various locations where remanufactured boards had bad components (the transistors were changed but not some of the other components).

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.

A lot of these had problems with the lamp door; you need to remove the door and take a careful look at it edgewise---heat from the lamp can warp the door.

Notice the small plastic peg on the back of the door--when installed it engages a lever which is a safety switch so set cannot be operated with door removed.

If door appears slightly warped what I do is engage the lever (usually tiny and blue in color) and turn the set on.

WARNING: IF SET COMES ON DO NOT LOOK AT LIGHT FROM LAMP DIRECTLY. If set works with lever engaged you need to replace the door (EBAY has sellers with most of them) and DO NOT OPERATE SET WITH DOOR REMOVED OR REPLACE OUTER SHIELD AS HEAT FROM LAMP CAN DAMAGE THAT WITH DOOR REMOVED.

Before you rate this solution let me know if you have questions or what you find; engaging the lever will either rule the door out or confirm it is your problem.

Replaced lamp in toshiba 46hm84. still get


Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php The ballast is the most common failure besides the lamp.The ballast is the one that displays the lamp indicator if it's not able to power bulb or if bulb is not responding.Have a blessed one!

My PT-61LCX65 all of a sudden turned itself off and the Lamp indicator LED is blinking once every 5 sec. It will not power up. Can it be the lamp?


That is most probably the lamp. In some case the lamp is fine and the problem is the lamp high voltage board (ballast board).

The most coomon is always the lamp. The lamp cannot be tested . The ballast board must be tested by a technician.

The normal operation in this case is replaceing the lamp that cannot be tested. then, if you are within that 2% of the cases with ballast problem you replace the lamp power board or call a technician.

You can find parts here.
