Samsung dlp hln617w does not tun on

All 3 lights on front blinking? Lamp bad. Open lamp door and check lamp.

It sounds like the main power supply has a bad capacitor. its a typical issue with a lot of electronic. look on the main power board that the outlet cord comes in to the TV and check all the cylindrical components for swelling, leakage, or singe makes.

2 different brands and models listed here--for the Samsung inspect to see if color wheel is intact and not shattered---have to remove the lamp to see it.

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 is finished. Order a new lamp using the code on the side of the TV. Remove the lamp door on the back of the TV (4 screws) and then remove the lamp (1 screw). Have a look at the lamp... is it damaged? See my tips & tricks if you want to learn more about the lamp.

In this case it seems you may have an issue with your ballast. Either it's going out or barely starting. I recommend you replace it

what i would do is crack into the tv and watch the individual parts being careful not to unplug anything while you take the back panel off.....turn it on and see what happens. let me know what happens

I went to sleep my tv was play i woke up and don't work so i turn it on popping crack sound and it shut down what do nowno tv

all 3 lights blinking means lamp has a fault the service manual says replace the lamp. If you need the service training manual for that model let me know and I will post the link as the training manual has excellent trouble shooting breakdowns for that model DLP
