I have a 52 inch projection hdtv. every time I


Hi,

Well basecally Samsung most comont parts that go out are,
LAMP: The generic lamp will go from 3500 to 4500 hours and a phillips lamp will go for 6000 to 8000 lamp hours,
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. But you need to listen carefully for any strange noise like (CLIKING,HUMMING,BUZZING,WHIRLING SOUNDS) that will help younarrow down whats is wrong with yor tv bacuse the BALLAST wich is the board incharge of sending the correct amount of current to your lamp could be weeek and will not power up you will hear a cliking or electrical huming Also the color wheel is a commont part that goes out on Samsung and that will give you a vibration and a loud whirling sound,you can get more help and real good prices at http://www.discount-merchant.com/?click=52978 good luck and keep us posted

hello
  1. Press "Display" on the remote, followed by the 5 button, then the sound up key, and "Power On." Do this while the TV is in Standby mode.
  2. Step 2 Then press "Jump" 3 times to enter the DE Service menu. The TV screen will display the total lamp time hours.
  3. Step 3 Reset the lamp time by pressing channel 3, then mute, then enter. This will put your lamp counter back to 0.good luck

PCB repair should be done by a qualified tech. Your problem could be HV cap bad,xformer defective or bad connection problems and pico fuse open. Check 2KV cap near xformer.
