Lights not working, and can't find the ballast location


The ballast is located down by the compressor if you take off the cover the ventilation slats. Then in the very center where there is a plug from the compressor plugged into the side of the center support as a cover on the front of that open the cover and inside you'll find The ballast.

How to Replace the Ballast in a Samsung DLP


Fist what is a TV ballast?

A television's ballast is a device connected to the lamp that provides an electric current, keeping the lamp operational. If you have a new lamp that isn't working properly, then you will more than likely need to replace the ballast. Replacing your television's ballast is less challenging than working with other parts of a Samsung Television, and is something that you should be able to do yourself.


  1. Remove the back panel of your Samsung DLP television, and then remove the lamp.
  2. Carefully unscrew the cover sensor switch, which should be located near the bottom-right side.
  3. Remove the two screws holding the lamp connector in place and slide it out.
  4. Remove the screws holding the inside unit of the TV in place, and very carefully ease the right side out, allowing access to the ballast.
  5. Unscrew the circuit board, remove the two cables going to the existing ballast and replace it with the new ballast in the same fashion.
  6. Put the inside unit of the television back in place and screw it in.
  7. Reattach the cover sensor switch.
  8. Reinstall the lamp and screw the back panel of the television back into position.
hope it works..

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

How to access ballast on pt-50lc13


The ballast is hard to completely remove--one plug all the way to the left as seen from rear and to the front, this does not really need to remove that.

The box is to the center and rear, unplug some plugs, screws and the box will come out far enough to replace the parts without removing the who thing from the set.

The large metal box with shields etc is the ballast.

WHERE CAN I FIND THE BALLAST IN THE MITUSUBISHI WD 52532 MODEL


hint: the two pins the lamp plugs onto go directly to the ballast which is really a power supply for the lamp.

not clear from all you have said if ballast is the problem===these sets had a lot of issues; anything, even too much dust on the fans inside will shut it down...........

Actually the lamp with the housing is seperated fro the ballast, if you change the housing it will not chnage the ballast, you will see the cables unplugging when you pull out the housing, that cable leads to the ballast.

I need to replace the ballast on my GDM 12 freezer and I need to know where the balast is located


The ballast is located on the bottom inside wall where the compressor is located. Its usaually mounted, and can be easily removed and replaced. The ballast is rectangular in shape and has a few wires protruding from each end. To replace simply dismount the bad ballast and clip the wires. Match the ballast to a new one, reattach the wires using wire nuts, and remount ballast.

Ballast location?


the ballast is right in the middle. you should see an electrical cord. open the 2 screws from the ballast cover. then unscrew the top and bottom screw from the ballast. the ballast should come off. cut the wires closer to the ballast, so that you can identify the wire with the new ballast, which will have the same color scheme.
