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???

Re: White Flashing

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.

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.

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.

you have the same problem I have. The problem is fixed by changing the new light bulb. The problem appears again after 1500 hours of use. You can keep buying new light bulbs or avoid it by not buying another Samsung TV.
