Question about Samsung HLN467W 46" Rear Projection HDTV

1 Answer

White Flashing I have a Samsung HLN467W after about 45 mins to an hour there is a flashing that starts from intermittent to every other second.  The Flashing is similar to lighting going across any colors.  I have replaced the digital board.  I think due to the time frame that it could be ballast or a cooling issue.  Any ideas???

    Silvera4 did you end up replacing the DMD board? Was this the solution? I have the same model and the same problem and am leaning toward the color wheel even though it is not making any noise.

DMD Control Module is flaking.
Could be getting hot if the fan has been compromised by dust. Take the back off. Clean everything with a brushy on the vac hose. Tape the cover switch shut and power up. Check for proper fan operation. Both should spin equal and quiet. May be too late for DMD Control board, though.

It normally takes any where from 45 min to at least 1 hour to compete the memory loss on the computer thus resetting the computer ok
so please tell me if you did this if so there is more that we can do ok

Hi I have a Samsung HLN467W, a 46" DLP TV. And after 50-60 minutes, it starts to flicker white, like lightning flashes. But the whole screen is not blank white, it's more like the images are...

It seems color wheel problem in your tv that gets problem after some time and you hear high pitch noise along with picture flicker.
Color wheel need to be replaced to solve this issue. Required color wheel is available with (click to view image of part and price info) and it is job of qualified tv repairman because light engine will take apart for that.
Hope these info will help you.

Those links should help you understand what's going on. You need to get a service manual, like those supplied, but for your exact make and model.

Can't set the ttime

Press and hold the hr button for 3 seconds until the 12:00 starts flashing, then press the hr button again to set the hour. Then, press and hold the min button for 3 seconds until flashing starts - press the min button until minutes set.

Samsung HLN467W Flashing "LAMP" LED

remove the lamp and visually check if inside looks broken.if visually do not see any thing wrong,check if you have 300 volts dc supply on the ballast which starts the lamp.if you do then the ballast may be defective.if you do not then the power supply should be checked.
the lamp should always be tried first especially if is older than two years.
note - be aware about the switch at the door lamp.the door should be closed,otherwise tv will not work.if you remove the back cover,make sure to bypass the switch temporarely so you could work on the set.
