Panasonic Plasma TH-42PA20 picture reset issue

My Panasonic Plasma TH-42PA20 seems to lose colour and ends up with a basic green tinge. Can you help, please? I've had the set from new and, as a pensioner, can't afford a new one.

SOURCE: Blinking Red Standby Light - No picture

The six blinks indicates that an internal fan is either bad ot blocked by dust or debris, You should be able to look in the back of the unit and see some cooling fans. Chances are one on them is not turning and will need to be replaced

Try to replace the Main Power Supply board first.

this means your tv has a intermitent problem when the clour ic gets heated up it starts to give you green..so therefore you need to take your tv to a tech to have it repair by replacing the colour ic. good luck.

The pictures are mostly green - like instead of black it shows green


It's called Cyan and it's sound like you are having a problem on your D-board. Look for capacitors bulging out and replace first if not then order D-board

The color on my tv has gone crazy. There's either a blue tinge or a yellow tinge when I adjust the colour (so either people look like they are faintly related to a smurf or have scurvy!!). I am also...


I would suggest to unplug the TV from the AC power outlet first, wait a couple of minutes to plug it back in. If that does not work, the main board is defective since is not providing proper video info to the main digital controller board (D board). The Main board part number is: TNPH0721AJS or TNPH0721ADS. If you need to verify the main board part number, you will need to remove the back cover of your plasma to check it out.
Let me know if you require further assistance.

Everytime I use hdmi the colours are mostly green


I have a panasonic th42pa 60a SD plasma and I get the same problem WHEN USING CERTAIN HDMI cables. I had a connexa brand with my samsung stb that i got with the TV and I had no problems., but i had to replace that because one of the ends "frayed" when it was accidently yanked out of the tv socket. A high quality monster cable did the same green screen you describe. The cheapest "Crest" from Big W that did HDMI standard 1b worked fine, but a Rank Arena from Target did not. So buy the cheapest HDMI 1b cable you can, the picture quality and sound is the same as the more expensive stuff. BTW I tried a HDMI 3 way splitter as well and it did the same green screen thing, but it worked on a later model panasonic plasma. I think it is Pana's poor HDMI implementation.
