The ballast is on the other side of the lamp compartment. the lamp plugs into the two short leads that are attached to the ballast. Its a small circuit board.

Tip

How To Know if it is the Lamp, or Ballast, that has failed.


Hi There. This is a very common issue with most rear projection Televisions. For example, you and your loved one are watching a great, and captivating movie, but suddenly, the screen go's blank. There is a "Lamp" signal in the right or left upper corner of the screen, and its flashing. Im sure at this time, you are very upset, and your loved one is, as well. don't worry about a thing. I will explain what is actually going on in this situation. In most situations, this will be a blown lamp, but in others, this will be a failed ballast.

Ok, first we will go over a few symptoms. The first will be the "lamp"

LAMP FAILURE

The lamp has only one symptom of failure. this will be a single pop, or a faint overheated filament smell. Normally you will here a single pop before the screen will go blank. The sound may continue, in some models.

BALLAST FAILURE

The ballast is a little tricky to diagnosis, audibly. There are three main symptoms of failure here.

1. The TV will usually give a "LAMP" failure code, even when the lamp has been replaced.

2. The TV will not make the normal click noise, or surge noise during start up. The absence of the start up surge noise is one of the quickest ways to determine whether the ballast or power board are bad, other than the lamp, itself.

3. The TV will make erratic, or rapid clicking noises during start up(5 clicks for every 3 secs). This is an indication of a weak ballast. It is unable to power up the lamp.

Now. Once you are faced with this issue, I would advise to simply test the ballast. Once exposed, you can visually inspect the component's as well. I will guide you through this with my procedure below.

The Lamp, and ballast are housed in close proximity of each other in most rear projection DLP sets. There is an access panel located on the bottom rear side of the unit. Most standard Phillip head screw drivers will due. Once the screws are removed from the rear access panel, the panel can be removed, and put aside. Once the panel if removed, the internals will be exposed. The Light engine platform is where the engine, and lamp housing will be mounted. The lamp/ballast housing is slightly to the right of the light engine. It will be black, in color. Ok, gently unscrew the light engine platform screws,and separate all harness connection to the engine,before pulling the platform away form the cabinet. Make sure the wires going to the digital board are removed from the light engine Assembly, and lamp/ballast housing as well. It is very important to make sure that all wires are disconnected from the light engine, and lamp housing before the engine platform is pulled away from the unit cabinet. Ok, once the platform is removed from the unit, simply pinch the plastic clips and pull to remove the vent housing. Now, once the vent housing is removed, the ballast will be exposed. Pull the smaller connector (ballast control cables), out carefully. Be sure that you don't damage the connector or the cables. Ok, now you release the lamp housing, and remove it. It is just to the side of the ballast housing. Once the lamp housing is removed, the ballast will have a few screws holding it on the engine platform. Simply remove the ballast mounting screws, and lift up the ballast housing of the platform.

NOTE_Normally, the ballast has Two connections to the digital board and power supply. The third connector goes to the lamp. Connector one powers the ballast, while connector two, gives operation instructions to the ballast.

Ok. Once the ballast housing is removed from the platform, place it on a separate table, and remove the ballast housing screws to expose the ballast circuit board and components. This is where you will need to access a multimeter. testing is needed to confirm ballast failure. Although there are visual indications that will confirm failure, i would suggest to test as well. Observe the ballast before proceeding. If oil is leaking from the ballast, stop here and remove the ballast. Leaking oil indicates that the ballast is damaged beyond any doubt as the internal seal has been ruptured by excessive heat. This is one of the visual indicators that will require you to go ahead and replace the ballast. If there are no oil leaks visible, move on to the testing procedure. Turn the Volt Ohmmeter to "ohms" and touch the ends of the two probes together. The meter should show continuity or a direct short. Touch the probes of the meter to one of the white wires and one of the colored, blue or yellow, or any wires that comes from the ballast. This should show a short or continuous circuit. If it does not, the ballast is bad and should be replaced.

This will conclude the procedure. This will prevent you from purchasing the wrong part, when the "LAMP", code appears.

Here are a few other models that my tips will cover. HLT4675S, HLT5075S, HLT5675S, HLT6756W, HLR5067W, HLR5656W, HLR6767W, HLT5076S, HLT5676S, HLT6176S

Samsung SP50L6HX, I replaced the Lamp but still nothing.


Hi, Samsung haves a known issue with the ballast, once you make a replacement of the lamp, sometimes its harder to ignite a new lamp that has 100% of gas inside than igniting a old lamp that has maybe 60% or 50% of gas inside. Just in order to ignite the lamp, the ballast needs to send some High Pulses of Voltage, as high as 15 kV (that is the constant clicking sound that you are hearing). In order to resolve this you need to change the Ballast Board. I tried to look for your ballast with your TV Model # at samsungparts.com , but nothing showed up. You will need to find out which ballast part # you have in order to find it online. To locate the ballast part # please check the end of this video, you only need to take the lower back cover of TV off. http://www.youtube.com/watch?v=0jr_9A5Xd2Q

Tv was working went off LAMP flashing and would not come on.


Lets go back to the beginning... What were the original symptoms? Was it just the clicking or were the lights on the front of the set flashing too? With the new lamp, is there any thing else other than the clicking? If not, then the problem is likely to be the ballast. The clicking could be the lamp attempting to "fire". With a defective ballast, the lamp won't fire and the set won't come on. If you choose to replace the ballast, DO NOT use the old lamp. It is relatively common for a defective lamp to smoke the ballast under certain conditions. Also, it is possible that the original cause was the ballast that failed and took out the lamp with it.

Please keep us posted.

Thanks,
Dan
