Samsung DLP TV time, temp and lamp lights blinking... won't turn

change memory ic

I am having the same problem

Hi,


May I know if the unit won't power up, has a three blinking led light at the front panel? Also, please check if the grinding noise is near the lamp assembly.

Had similar problem. Thought it was the lamp. Examined old lamp but it appeared to be good. Ordered a new one anyway. Changed the lamp but the TV screen would not come on. It would make the usual noise as it was going to come on normally but it would cycle 3 times & then turn off. The LED lights in the front panel would indicate a defective lamp. Then read about the ballast. Changed the ballast & still same problem. Tried starting the TV without the lamp installed & noticed that the color wheel did not spin. Removed old color wheel & discovered it was broken. This appears to be the cause of all of my problems. I wish I new earlier of the test-turn on the TV without the lamp being installed & check to see if the color wheel is spinning. Would have save money on the lamp & ballast.

The "lamp" in this set, I think, is called the "DLP" in the parts listings. That part is number: 4719-001960 and can be purchased from tritronicsinc.com for $249.75 plus shipping. Use the guest account to access this info.

Hope this helps,

When it shuts down, do the LEDS on the front blink? There are 3 of them. Standby, temp and lamp. Do any combination of the 3 blink when shuting down. I could tell you where to start just by those lights blinking.

Check your color wheel. There is a DIY guide for replacing the color wheel. Mine did the same thing yours is and my color wheel was all busted up. Unfortunately after replacing the color wheel my set continues to do the same thing, but this could mean I need to replace the ballast as well.

lamp shuts off first..with sound still on and black screen.then turns off and has three blinking lights on front panel.

replace the lamp.

When the set shuts down you need to see what lights are blinking. For example: Timer/ Temp/ lamp on the front panel. You should also count the number of times they blink and the sequence. Most DLP`s give an error code alerting the technician to check the balast, lamp, or fan etc. for malfunctions. Unfortunately I can not tell you exactly what is wrong given the current information. Howrver, the last Samsung I repaired for shutting down had a bad light engine.
