Question about Panasonic Viera TH-50PZ85U Plasma TV

1 Answer

Picture quality deteriorated

Screens are increasingly grainy-looking and colors seem washed out somewhat. skin tones do not look natural etc. sometimes it seems to be more noticeable than others. but overall the picture quality has declined since it was new 4 months or so ago. is there a reset or way to diagnose to pinpoint what is going on?

Most like one of the scan drive boards is failing. It would need troubleshooting to determine which board is weak.

Call panasonic on this. Their warranty has been extending for just this problem.

This problem is caused by currupt eeprom data on the LCD drive board


If they don't do anything about it, do a search for part number # LSUQ0100.

That is the tool we use to reprogram the eeprom.

SOURCE: when the screen has a light picture you see pink

Howdy,
The problem is with the EEPROM in the TV that needs to be reprogrammed. But you need to have the proper Correction Tool (LSUQ0100).
I don't think it's available to the public. Call a Service Company, but make sure they have the “Correction Tool”.


Thanks for using FIXYA, big IRISH.

You may have to purchase a hair stripper and recolor your hair.....FIRST though, wash your hair with shampoo 5 times consecutively (wash, rinse, wash, rinse, etc). After the fifth wash, condition and leave on for 5 min then rinse and see if that toned it down. If not, purchase a hair color remover (stripper) and recolor your hair with a more tame shade.

I think it is your screen resolution it needs to be increased, go through my published guide entitled How to set your Desktop Screen Resolution?

Increased resolution and colour quality will give you an excellent picture.

Red Tint on Screen


This is normal and is a color calibration issue.

For correct color, NEVER use the "WARM" setting. Why? Too red. You cannot get REALISTIC or ACCURATE color using the "Warm" setting.

Since we are speaking of Samsung, first avoid the "Flesh Tone" adjustment. When things are set correctly there is no need for this adjustment. It is a quick fix and not for the "discerning eye".

1. First, access the "Color Temperature" menu. From here select "Cool2" or the coolest temperature setting.

Note: For Samsung use "Cool2", or if not available, "Cool1". Samsung has inadvertently increased calibration confusion by issueing TVs that have just "Cool1", and TVs that have both "Cool1" and "Cool2" :0[

For other brands, use "Cool", or "High", or "+6500k". Anything lower artificially reddens the picture and compromises detail.

2. Now return to the color settings and reduce "Color" to between 30 and 40 (on a 100 scale). The sweet spot is just near the place where the color rapidly washes out.

3. To round out the color palette, move to the "Tint" adjustment and ADD a couple (3-5) clicks to the GREEN.

Adding the touch of green is what is needed to take out the last bit of "pink" and will make all the tones and all colors display properly.

I hope this helps!

My pictures display poor image quality on the screen or when you print them out.


PhotoPC 800 captures images in 24-bit color (16.7 million colors). Your pictures will not display maximum image quality if your monitor or computer's video controller doesn't support this color depth. You may need to upgrade your system to achieve the best possible image quality. If your pictures look better on the screen than when you print them out, you may need to upgrade your printer. An EPSON Stylus ink jet printer, for example, provides excellent image quality. If you used drag and drop to insert your pictures, they may appear grainy. Try importing them into your documents instead.
