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..

Loud noise when starting sometimes will shut off takes 3 or more times for it to keep running just changed the bulb guess this wasnt the problem is it possible that this is a problem with the fan?


If it's not a bulb that needs replacing its most commonly a problem with the ballast, which provides a steady electrical current to setup and operate the lamp.

i have a mitsubishi tv that cuts off after about 30 seconds and lamp light is red but i replaced lamp 1 week ago.


Hi

Well if you have replace the lamp just recently what could be happening here is that your ballast is not working properly and is to week to keep you lamp running,The definition of the ballast:
How It Works
The lamp itself typically uses AC current and about 15,000 volts to ignite the lamp's mercury vapor gas. The gases inside the lamp react when electricity charges up the mercury gas creating very bright light. The voltage drops to keep the flow of electricity to the lamp.
The lamp works with the ballast to project light into a light engine that separates the colors of the light, then recombines them with an image.
The image is then reflected on the back of the TV and then onto the screen.
If the ballast is to weak it will no have enough power to send the 15,000 volts to get the lamp ignited

My samsung projection tv picture is going dark


Hi

the main reason is could be that you lamp is old and needs to be replace, Phillips lamps will give you from 6,000 to 8,000 lamp hours and if you get a generic lamp that will give you from 3500 to 4500 hours let me give you an insite of the lamp technology:
Background UHP Lamps are used widely in DLP and LCD projection displays. The lamps are not extremely complicated
and provide a light source for your television or projector display. Philips lamps have very low failure rate
and are often blamed for another faulty component such as a bad ballast, color wheel, light engine, or
cooling unit. The lamp itself is encased in an enclosure, meant to hold it in place and connect it to the ballast. How It Works The lamp itself typically uses AC current and about 15,000 volts to ignite the lamp's mercury vapor gas. The gases inside the lamp react when electricity charges up the mercury gas creating very bright light. The voltage drops to keep the flow of electricity to the lamp. The lamp works with the ballast to project light into a light engine that separates the colors of the light, then recombines them with an image. The image is then reflected on the back of the TV and then onto the screen. So in other words more likely your lamp needs to be replace ,and you can find this lamps at http://www.purelandsupply.com/Samsung-DLP-TV-Lamp.html or ebay or http://www.discount-merchant.com/SearchResults.asp?Search=samsung%20lamps?click=52978 please keep us posted and good luck Samuel

I HAVE AN HCM 4215W SAMSUNG 42 INCH TV THAT WILL WORK FOR ABOUT 20 MINUTES THEN SHUT OFF...I USE THE REMOTE TO TURN IT ON BUT ONLY THE RED LIGHT COMES ON. IF I UNPLUG IT AFTER ABOUT ONE MINUTE THE LIGHT GOES OFF. I PLUG IT BACK IN AND THE TV AUTOMATICALLY COMES BACK ON...THAT WILL LAST FOR ABOUT 5-10 MINUTES AND IT SHUTS OFF AGAIN


Having in mind that a generic lamp will give you 4500 to 6500 lamp hours and the Phillips will give you 6000 to 8000 lamp hours and that you TV is 4 years old more likely you are looking to replace you lamp;The lamp itself typically uses AC current and about 15,000 volts to ignite the lamp's mercury vapor gas. The gases inside the lamp react when electricity charges up the mercury gas creating very bright light. The voltage drops to keep the flow of electricity to the lamp.
If you can hear your TV fan working is NOT you power supply,but if you hear a constant clicking you BALLAST needs to be replace,
A ballast is an electrical component used with a fluorescent bulb (or mercury vapor lamp or arc lamp) to conduct electricity at each end of the tube. It supplies the initial electricity to the bulb that creates light, and then it regulates the amount of electricity flowing through the bulb so that it emits the right amount of light.
