MY SAMSUNG HLN 507 WX/XAA T.V. IS MAKING A WHINING SOUND WHEN I TURN IT ON


Your color wheel is going bad, when it fails the TV colors will be way off and it will shut down. They range from $50 -$125 . Here is one for $98 for your tv. http://www.amazon.com/Projector-Replacement-Samsung-HLN507WX-HLN567/dp/B00HJOLQ7G

When turned off the tv makes a whining sound (not the expected whining noise) and then sounds like a wheel (like on Wheel of Fortune) slowly winding down. Yesterday it didn't come on (sound, no picture) so...


The whining if it sounds like a mosquito type whine! it can be a capacitor, i have same issue, you can usually hear when u are on standby but if your hearing like a "wheel of fortune"! and slowing down would likely indicate it's a fan which is possibly covered in dust and the whining is the fan stopped trying to power forward or it slowly moving and slowing down. If you think it's the fan you should unplug your TV to avoid the fan burning out then have someone who knows what their doing take a look at than fan for you and clean the dust away from it, you may be able to get some access through vents in the side and can try your vacuum cleaner in those vents while TV is unplugged but i'd not go messing inside a TV without wearing some rubber gloves!
Looks like the engineer would need to remove TV casing, check fan to see if it is blocked with dust or not, or if just failing for other reason then either clean or replace. If you don't get it done and the fan fails to cool the TV your risking other vital components overheating and breaking for good so best get it looked at, sounds like the fan to me...

When press power button, power light comes on, but tv does not come on


Does the weird noise sound like a whining noise? Like something is spinning? If so then your color wheel is going out.

Rear projection tv wont come on. PLEASE HELP


If the set uses a lamp it MAY have a color wheel--when they fail you get a high pitched whine and or grinding sound--also often described as a fan like noise.

this is a part of the optical light engine and may not be sold as a part by itself.

If you remove the lamp and look where it faces you should if it is there be able to see it--missing any pieces or shattered and it is bad.

This tv is under five years old?Yes,it is worth fixing.Over five,i would compare the prices for a new LCD tv and the quote priced from the Tv Tech.for the old tv.This tv have high voltage problems around the Deflection circuitries area.Could be any things burn in this area.The high pitched whine sound,i'm sure it is from the FBT-the high voltages flyback transformer,high voltages current have no where to go.Must hire a tv tech. to troubleshoots and replace parts on the Deflection circuitries area.Also the FBT could be dead too,because HV Current bounces back forth and have no where else to go.The prices to troubleshoot unknown problems is about $400 bucks and plus cost of replacement of parts.

PICTURE STOPS & DETERIORATES THEN GOES BLACK. WHEN I TURN SET OFF I GET A WHINING SOUND (FAN?) FOR 20 SEC. & THEN SET TURNS OFF


The sound comes from the color wheel and not a fan,common to samsung dlp tv's which can be the cause of the shut down.

RCA HD61LPW42 - no picture


I haven't worked on an RCA DLP but have on Samsung DLP, based on your description it sounds like the color wheel is bad. Take the back off and turn on TV make sure its not a fan making the noise ,but most likely its the "wheel" it is inside the light engine probably right next to where the lamp is plugged in. If the whine comes from this area definitely the wheel.

HLP, HCN HL-S The Start-up Problem or/and
3 LEDs in the front blinking.

Unplug the set, pull out the lamp module (not all the way - leave it on the track) and push it back in.

Power issues (Tv not turning on) were typically due to faulty ballast. While the TV reports a bad lamp it is the ballast itself causing the issue. Samsung is well aware and will replace both the ballast and the lamp (since the lamp can be prematurely aged but the bad ballast). After replacment most people stop having issues.
