Question about Philips 42PF5521D 42 in. HD-Ready Plasma Television

1 Answer

Need settings because of rubbish picture

Hi, I have a 42" plasma tv, model number: 42PF5521D/10
The problem i have is that i cant quite seem to get the settings right for any picture through scart. i keep getting dead 'blue' pixels in the top left hand corner of the screen after 20 minutes of watching anything, it has slowly got worse but it started not long after i got the tv, so i tried as best i could using a 'CARS' dvd with the THX Optimizer to set the picture settings but it hasnt helped, and when i watch football or snooker, the green of the pitch or table seems fuzzy and pixelated, so I was wondering if you had any idea of the best picture settings i.e brightness,colour,contrast,sharpness,colour temp. any help would be great and hugely appreciated.
If you need to know, i am sat 8 feet away from tv, the tv is opposite the window (facing it) but mostly i have them drawn if too bright, my room is usually well lit.
I thank you for your time, Phill

    Hi Interestingly enough i have the very same problem. I brought the same T.V in march 2007. On the left hand side of the set i am getting what i call Blue mist, I assume it is dead pixels after reading this post. I have tried everything i.e XBOX 360 via HDMI, SKY via scart, DVD via scart. and am getting the same problem, which is very fustrating!!

There is no right or wrong setting for the TV, but I find the following give about the best results:

  • Contrast - 65 maximum
  • Sharpness - 2 maximum
If these are set any higher, the picture becomes very grainy, particularly around defined shapes.

  • Contrast + - OFF
  • NR - ON (If applicable)
These settings will need to be changed for each of the following:
HDMI 1& 2
  • EXT 1, 2 & 3
  • Analogue tuner
  • Digital tuner
The problem you describe, is usually with a satellite or cable box.

Unfortunately, there's nothing much you can do about the dead pixels, but the settings may make them less obvious.

    There are a few settings you can change on the Sky box too.

    Go into the picture settings menu - Services ---> System Setup ----> picture settings

    Make sure that Picture format is 16:9 (1st option)

    Also, make sure that Video output is set to RGB, NOT PAL.

    RGB gives a much more stable picture than PAL. You may need to connect the Sky box to scart 1 of the TV to get any benefit.

    If you switch back & forth between PAL & RGB you will notice that the shimmering around the Sky menu screen disappears.

I have a 42 inch philips plasma tv with a broken screen, could i replace it with a screen from a panasonic 42 inch tv

No--this is called a PDP or plasma display panel and no two (even same brand) can be interchanged.

The cost of a Panel exceeds the cost of a new set--broken screen=fatal issue.

My samsung tv model number is sp50L7hx it's 6 years old, when I turn it on it's a not really nice picture just nice sound, after 2 hours the picture is off just sound .... after I was switch off TV...

This is a plasma screen T.V. and doesn't use a lamp. You are probably correct in thinking it's the T-Con board. This board is sometimes a pain to get it. When you get to the board, look up the board number on the side on e-bay or other internet resources for the lowest price if you're comfortable changing it yourself.

42 plasma tv started experiencing the well known power off red light symptoms. Was able to power on & off for a while to get the set on. Right before the capacitors came in the TV would not power on...

Only if it is completely dead. If you have lights or LED coming on then it's not the main fuse, I would say that you changed the caps, but there are some that you missed. Look hard again and also for maybe a resistor in the power supply.

42" plasma tv problem

Hello, If you are referring to the actual shape of the prongs coming out of the tv plug(refer to figure): prs1-6980390t98.jpgif the prongs look like this, you will have to acquire an ac adaptor for your TV, this adaptor you can locate at any radioshack store, and sometimes it's called foreign ac adapters for US use.
or simply look at the radioshack webpage, it should be listed under ac adapters.

Hi. My Philips flat TV will not show any picture

I had the Same issue. on a 50PF9431D/37 set. Many Plasma Set's use a LJ44-00118A PS-505-PH Power supply from Samsung. Known to have this common problem. If you can, or have a friend that can Solder components?. Unplug your set remove the back panel & locate your power supply. It will be the PCB in the center of the set just above the Video/Audio connections. Is a Link to a photo of the PCB. Make a note of the locations of all cable connections then unplug them all. Un-install PCB, Check all Fuse first. I believe their is 5 or 6 of them on the PCB. Then replace the two 3300uf 10v 105C Radial capacitors at C8060 & C8059. Look to see if the Caps are deformed and or split at the top. The location of the caps are in the Lower bottom edge of the PCB. A local shop may Carrie them if not, digi-key has them. Part # Total cost was $7 with S/H.

Issue with LG Plasma tv model # DU-42PX12X

Another "same probelm"

My set has encountered this magical 50/50 split screen and it seems to be quite a problem since I am not the only one researching this issue. LG was of no use because of course it is just out of warranty. Any solutions on fixing this or am I out of money in buying a new plasma?

Philips 42pf5521d - no picture, blinking green light

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, [Exclude the model number] in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.
Counting the number of blinks to Philips TVs is entirely different to that of other brand TVs. It is not a direct count procedure. The site have details about how to count the number of LED blinks [Fault Codes] to Philips brand TVs are given; along with details of the faulty circuit location.
