Chirping Sound From Back Of Samsung HL-R4266W DLP TV

I have intermittent short chirps coming from the set on all channels; it's connected to a Comcast HD cable box and other than this no apparent problems. Replaced lamp earlier this year; have 2000+ hours on new bulb. See nothing on the Samsung FAQ related to this. Any ideas? Thanks.

SOURCE: My Samsung 50" DLP HDTV keeps humming when the DLP lamp comes on.

Hi, you have one of two problems, either the color wheel is going or one of the cooling fans are going, the color wheels are a very common problem in samsung dlp`s, sorry I can`t nail it to a specific part but I`d bet it`s the color wheel as they are notorious for failing in samsungs, video-tek

SOURCE: 5 mostly green verticle lines on all digitle channels. HD ok.

I just called customer support and my issue is now fixed, to my extreme surprise.

It sounds silly (and a tad embarrassing), but here's what I did:

1) Unplug the TV
2) Wait 30s
3) Plug the TV in
4) Test

Apparently even if the TV is "off" for a few days it never fully shuts down unless the power is unplugged. Not sure if this will help anyone else, but I had the exact same problem others are describing. Good luck!

SOURCE: installed new lamp/how to reset the lamp hour meter on samsung (HL-S4666W)

Here is the procedure for resetting the lamp timer.

This is a quick reference guide to show you how to reset your Samsung DLP TV’s lamp hour meter or hour counter. Resetting the counter is a very simple procedure.
Begin with the TV powered off.
Point your remote towards your TV.
Press:
Mute + 1 + 8 + 2 + Power.

Your TV set should now say “Loading Factory”.

Browse down to “Option” then press Enter (or the right cursor button).

NOTE: The Mute+1+8+2 buttons needs to be pressed down consecutively and fairly quickly. If your TV does not enter the service menu after using this combination, you can substitute MENU instead of MUTE. This seems to work for some sets. Also, the right cursor arrow also acts as the ENTER button, so try it if you’re having difficulty with the ENTER button.
To exit the service menu, hit press the EXIT button or just turn off your TV (remember not to turn on your TV immediately afterwards!).

I hope this information allows you to resolve this issue.

SOURCE: Samsung DLP model hln617w won't turn on (not bad bulb)

Samsung is notorious for having bad color wheels in their DLPs. Well lets just say they are like toasters, they only last a certain amount of time. If the color wheel isn't spinning or is broken, the set will power down almost immediately after you hit the button, you may not even hear the entire fire up jingle. Check the wheel, if you can see the bulb light up for that split second. Actually, check it whether the bulb lights up or not.

SOURCE: Samsung 50" DLP - Lamp Light Blinking after bulb replacement

Listen closely. The tv should make a high pitch whine as it turns on. If it does wait and see if it tries this a few times. If yes then check the bulb, I have seen cases where the lamp shoves the power connector back into the set. If the tv starts with a grown or heavy vibration noise, then your color wheel may have broken and needs replaced.

Poor sound cqality on a Samsung DLP TV


If you are receving your HD via a cablebox, check the volume and audio settings in the box's menu. Some boxes have internal volume controls. If the level coming out of the box is below a certain level, you may experience low or poor sound quality. You can also check the audio settings to assure that they are set to the original settings.

Phillips Magnavox Proj. TV only makes cyclic chirping sound


Most common reason is shorted convergence chips. Goto the site www.TvRepairKits.com and get their "chirping set" repair kit.

No picture, no sound, just chirping noise coming from back


NO - - signal did nothing to the set... Sounds like a shorted HOT (horizontal output transistor) and the feedback your hearing (chirp) is on the horz. transformer as it tries repeatedly to startup... Don't allow it to do that for too long...

No power just a chirping noise.


Chirping means the power supply is being loaded down by a short in most cases, likely a bad convergance IC

When tv turned screen is blank and chirping sound comes from back


A chirping sound usually means that one of the secondary supplies has shorted, most likely the horizontal output transistor. The power supply "chirps", which is the sound it makes when it protects itself from drawing too much current. The set should be serviced by someone with experience in Philips projection TV'.
