If the pip is fine then the digital board is bad. Have it replaced by an authorized Samsung service center as the hex settings have to be copied from the dmd to the new digital board

remove the back cover u will see the fans one for the ballast and the other for the lamp

Sounds like a door switch is not making proper contact--or has been damaged. Check the lamp door switch and see if it is properly seated and the pin on the door is hitting the leaf of the switch.

You need a color wheel--common on these sets. Get a real phillips bulb and you should be set for awhile. The cheap generic bulbs are fine to get you through a few MONTHS....but NOT much longer. . An E22H-120/132 watt lamp is correct--and if you can replace just the bulb-(NOT hard at all to do) it will save you a LOT of money.

just from personal exp the easiest thing to do may fix or at least make it better. if u see puffed and leaky caps on power supply replace capacitors. if really dusty clean. both previously mentioned and both helped me. my tv was completely dead and replacing caps got it to power back up and work. it takes two trys to come on but works great so far. then i cleaned every nook and cranny with a small vacuum hose and different size/angle brushes that could be attached to hose. i only took out the psb board with caps and didnt touch anything in there that i could mess up. just cleaning helped enhance the colors. right now this is the best picture ive had on a tv and it was completly dead when i got it.

Check all your input cables & be sure they are snug on both ends, also check all your wiring connections inside the TV. you may have not gotten something back correctly or properly.

EURO STAR LCD TV 32" BLANK PROBLEM

(Please check your model number - it appears to be incorrect, I believe it's HL-S5687W) 1) How old is the lamp? (how many hours on it)2) Is the lamp an original equipment lamp, or aftermarket?It's either the Lamp itself (it's not common for a sudden reduction in brightness), -or- the Lamp Ballast has gone bad. This is the power source for the Lamp, and although they usually die completely when they do go, sometimes they will act just as you have described... they fail into a "low power" mode.If the lamp IS an original mfr lamp, and if it's nowhere close to being near "end of life", then I'd say it's likely the Ballast.Prices for the original Samsung lamp run around $100 onamazon and others.The Ballast p/n BP47-00037A has a cost of around $50 to $100 online. Google those p/n in "Shopping"The Ballast can be replaced without great knowledge, but will require some dis-assembly, and CARE.WARNING - Dangerous, and even lethal voltages are present inside your TV set. Do not attempt this unless you are trained in these kinds of repairs. Leave the TV unplugged for several hours (or preferably a full day) before attempting such repairs.

as far as I know that set does not have a lamp timer to reset.

THe only alternative is buying a transformer by 60HZ vs 120hz,OR you can go some repair motor shop and reconvert the transformer by the frequency that you need.sincerely.ERNESTO CUADRA

Hello. You can check HDMI cable in this case. If you're using an HDMI port that's not working well or has been damaged, it could result in a darker-than-usual screen. If you switch the cable or change devices and the TV is at a regular brightness, this is the case.
