    the popping came from the middle crt i guess you call it

    i have the back off trying to pinpoint the sound and it made

    the noise to the left and above the splitter

    it came from above the circut board if you got the picture

    it was just left of the yellow plastic with the red dot on it

    kind of a purple blue hue

    Hello there. Just found this post and decided to ask for some assistance. I have a very similar problem with my Zenith Z56Z95D8. Recently, the picture went black...still had sound just no picture. Was told to replace the HV module board(part# 9-1674-03). As soon as I did this, the tv worked fine for a couple days. Now, to start tv I need to hold in the power button for it to turn on. When it come on there is a distinctive electric "clicking-popping" sound being made and the picture has a "electrical interference" at the same time as the sound. I can definitely trace the sound to the part where the HV module wire plugs into the bottom of what I would call a splitter block. There are (3) additional wires that go from this "splitter block" to each of the CRT's. The id sticker for this part is # A-17813-01. Is this the culprit part? What is this part called? Where to get a replacement cheap?
    Hopefully this helps Hank also with his problem...sounds almost identical.
    Thanks Alot for any assistance, don't have $$$$ for a new tv.

It sounds like the flyback or the HV splitter those are the two items that will hiss. It should be coming from the area where the flyback is. thats a large transformer with a large red wire coming out of it going into a Splitter that will have 3 additional large red wires each going to the three CRts. Let me know if you need the part numbers and where to get the parts with free tech support so you can easially install them yourself.

    The HV lead going into the CRT may need to be resealed. But without touching that red wire try to determine if its coming from up high on the crt or down near the circuit board of the CRT. Just dont touch the red wire alot of voltages are present in that large red wire.

Our tv is Samsung DLP HL-P4663W 46 in. Rear Projection HDTV-Ready Television After having our TV on for about 45 minutes it starts to make this hissing sound which starts low and gets louder and louder,...

This looks like a colorwheel symptom, does the sound is like a mechanical sound? high pitch sound? winding, whirling or screeching noise ? well if this is the color wheel, what i think it is, it seems that it is not working properly when this happens the DMD board recognizes that it is not spinning at the correct RPM and turns off the Tv for sercurity reasons, so if you want to replace this yourself what i recommend you to do is to open the back of the Tv and search for the colorwheel it can have missing parts or it could be shattered or it could not spin correcty, hope this info. can help you.
