Philips 32PW6517/6506: Noisy "wind in microphone" extra-sound!
Hi! Bought the 6517 (with the chassis L01 LS from 2003) about 2 months ago and returned it after 3 weeks! Then got the 32PW6506 (with the chassis L01 E1 from 2002) and have had it for about a month. Seems that I have to return this too! In both cases because of the faulty sound. The normal, intended sound is accompanied by a noisy sound like "distant thunder" or "wind in microphone". Also in silent passages of a movie or other content, but generally it is triggered off by and accompanies the intended sound. Obvious with the presets "Music" and worst "Theatre". Less obvious, but very annoying, with "Personal". Only with "Speech" the noise disappears, but so does most of the joy of sound! No change of the settings for bass or treble makes any difference. The same for stereo and mono. In the long run I find the noise unacceptable, also with the preset "Personal". In a danish AV-forum, I was told by a member that Philips in a bulletin about "known faults" had described a "wind in microfone"-noise " with some L01E-chassis, and that is is a software-fault to do with Ultra Bass (a part of Virtual Dolby) or something like that - and that it can be diagnosed with Philips' ComPair (PC-interface). Philips have found the solution for at least L01.1E og L01.2E! He hasn't heard/seen the fault on models with the A10-chassis (6526, 6515, 6516) and haven't seen the L04 yet (with the new PW6518, PW6618 and PW6408). In fact I've been promised a 6518 as a replacement as soon as the store where I bought it gets it. But how good/bad is that TV? And I really like the colours, geometry and fine details of the 6506. Needless to say that Philips don't know the problem when asked about it! I've noted the following facts: 1) The noise disappears with the preset "Speech". I assume that this preset cuts off the lower frequencies, indicating that the problem has to do with decoding the bass-area. 2) Worst preset is "Theatre". That preset accentuates precisely the lower frequencies. 3) Problem is present most of the time, watching movies. Most movies use Dolby Surround with a wide spectrum of sound. 4) Both models have a L01-chassis (L01 LS and L01 1E). Anybody similar experiences? Had the problem solved? Would really be nice if that's the case! Should also like to know if the problem is solved with newer chassis? |

I have a 32" plasma(brought last summer)) (dont know the model number off the top of my head so dont know if it is the same as yours) but i also get a high pitched hissing or a rumble which is lesser in speech mode. I just thought it was normal so maybe i need to take it back.

I hasten to tell you that all the TV's I've mentioned in my post is 50 Hz direct view CRT-TV's! And the noise I (and Philips) is referring to as "wind i microphone" is certainly very low-pitched, like "distant thunder", as I also call it. As an amateur rock musician I of course know about high-piched microphone-noise, but it is caused by interference and many other things. It's understandable that also "your" noise is lesser with "Speech", as this preset accentuates the middle area and cuts off both the lowest and highest frequencies to some degree.
