The only problem remain with the latest firmware is the shapeness issue with digital tv (sd/hd). The quality of image is good but in the image configuration i set 0 shapeness and advanced shapeness off but seems like it's at level 6/7. This high level of shapeness transform the quality in an artificial image with some artifacts in writings on tv (es. in news channels).
This issue is not present in analog tv so it's a firmware issue. I tried to put pc mode in the digital television but it's not possibile (when watch digital tv the pc mode option disappear from option menù). It's impossible that the shapeness issue is from the panel because this tv mount a S-Ips panel and all of us know that s-ips don't have issue with shapeness (it's a very good panel for people like me that use tv with pc).
I hope that soon philips release 2.19 firmware that resolve this issue.
Please forgive all my english errors but i'm italian and i'm not the best with foreign languages.
Thanks for attention.
Dezz, thanks for the detailed input on this product.
I was just going to purchase a similar TV, but the 3606 model. So I'm wondering if this line is also affected by the strange sharpening issue?
If so, then it's a shame and I probably won't buy a TV that has a decent hardware but is made worse on purpose by firmware to make people buy more expensive models.
In my opinion, these kind of issues are never solved because of all the bureaucracy involved.
The client is not the first priority these days.
how to set pfl4606
I bought a tv PHILIPS 42" PFL2606 some day ago.
I would know how tot set image configuration... because my colours sucks!
I use it only for sd, not hd.
Please, help me
for Sd image try to use this setting .... Image Smart Photo

please write in English (forum rules)!
Hi i bought 4606 few days ago,and i have a same problem,in my country we have only digital signal and sharpnees is not good on this tv,my bigger problem is that when i conect my computer with hdmi picture is catastroficly bad....can someone tell me is it possible to fix this and how can i do that..best regards bare984....
p.s Philips,is there any replys on this posts here,what is happening?
I contacted Philips today via support chat and asked, if there will be a fix available. My question was transferred to engineer group. And, unfortunately, they said that in their opinion sharpness isn't a problem. "Sharpness is a subjective point of view". So, no problem, no fix
Philips support also recommended to compare models in a shop. If there is some better one available.

Is it possible to post a picture of a sharpness pattern, with all resolution enhancements off, just to see how bad things are?
Tracking the 4606H bugs.
Hi Phillips (and your customers)
I've just picked up an 4606H (Swedish/EU version). Basically a good enough bedroom TV, besides a couple of issues.
1. The sharpness "bug" as explained, causing HD material and Text overlays to be distorted. Shame, since the panel is good.
2. MPEG artifacts causing visible "blocking". Take for example a fading red (light red in middle fading to dark red, as in the demo material played at Mediamarkt), while other TVs in the same price range reproduce the fading OK, rings are clearly visible on the 4606H. Shame, since the panel is good (do not see this in PC mode).
3. MPEG artifacts when the input is (deliberately) grainy (e.g., Tinker Soldier Spy), the MPEG decoder goes bezerk (erroneous blocks in the picture, even if MPEG artifact reduction is turned on). Shame, grainy material is not enjoyable at all (under VLC on the PC no artifices were visible but I cannot claim that this goes for ALL grainy material).
My guess is that these artifacts are all related to the MPEG decoding. As previously discussed the sharpness "bug" is NOT present in PC mode (NO MPEG), NOR in the analog tv decoding (NO MPEG), while present whenever MPEG decoding is done.
MPEG decoding consist of a set of mathematical operations (filters) operating on the incoming data and the current frame(s). The operations involve constants (scalars, vectors, matrixes, etc.) that not only reproduces the image, but also manipulates contrast, color, and sharpness. Presumingly parts (if not all) of the processing is done by dedicated hardware with some settable parameters (this allows us to change the picture). However there might not be a 1-1 mapping of settable hardware parameters to those shown in the TV menu, the relation is probably quite complex).
I'm no expert at MPEG decoding, so I can't tell exactly where things go wrong here, but to me it looks like the problem is caused due to saturating some register (intermediate calculation result) or having erroneous value(s) in some scalar/vector/matrix in the MPEG hardware. (The latter would somewhat resemble the infamous Intel floating point bug http://en.wikipedia.org/wiki/Pentium_FDIV_bug).
So bottom line, if it is a matter of mapping the menu parameters to parameters of MPEG hardware this should be fixable. Blocking artifacts caused by saturating calculations, could be fixed by recalculating constants (located in the MPEG hardware).
Question is wether you at Phillips think it is worth the engineering effort (as a low-end segment TV it does it job pretty well anyways, other brands have (other) bugs in their products etc...).
Or maybe ... my guesses are totally out of the blue... then please put me straight.

It'd be so great if you could enable zoom changing function in mediaplayer during usb playback. It's the thing that this TV lacks and it doesn't seem to be so hard to implement it in new software. If you care add it please.
Just for the record: "Sharpness bug" is still present in 2.19.
Hi there. There is a bug in firmware with my 42PFL4606H. My TV is connected to my PC(Win7) via HDMI and it is used as a second display. When I watch my TV(DVB-C) and PC is turned off - all is great, when my PC is powered on, but I'm not logged in windows - all is great. But when I'm logging in - windows initialized second display(my 42PFL4606H) and then image and sound of DVB-C channel become distorted. MPEG artifacts are present on picture, different noise in sound. When I'm log off my windows - all is great. I have a newest firmware (2.21), last updated today in the morning.
Sorry for my bad English

I read most of the posts in this thread but i have a bug to report of myself as well.
I bought the 37PFL4606H/58 like 2 months ago and so far i love it, but there is a bug in the picture that bothers me a lot every day. So, i will try to explain how the bug looks like.
When i play movies via USB, on some of them not on all, there is like interference or distortion in the picture not sure how to explain it exactly but its a bug in the picture.... small squares appear in the picture it looks like bad graphics and it lasts like few seconds only... (for example when i watch Game of Thrones i always get that bug during the beginning song part of the episode). Has anyone had this problem ? Does anyone know whats causing it and how to fix it ?
Please help if anyone knows anything about this problem because it bothers me too much i cannot watch a good movie in peace im always looking for those squares to appear...
