Panasonic HDTV tint too green, color level too high

[samijubal]

I just got a Panasonic 27" HDTV, I use a progressive scan DVD player in HD mode. Everything is green and the color level is way too high. I can set the color and tint to 12, factory setting is 31, there is still too much color and everything still has a green tint. It's also more green on the right side of the screen than the left side. I opened the TV to look for adjustments, there are none. I got the TV really cheap and would like to keep it, but it's unwatchable the way it is. There are no magnetic sources anywhere near the TV. Is there anything that can be done without messing with the picture tube itself? If not I guess I'll just have to sell it.

There is nothing inside a TV that a consumer can adjust. There are a lot of things which can kill you, the tube being one of them.

You don't say if the picture is normal when watching regular TV or watching DVD in standard definition mode? You also don't say what kind of connection you have between the DVD player and the TV; composite, S-Video or component?

Just the green tint could be a cable problem, but it should be the same all across the screen. Try different cables and make sure the component is connected to the right sockets on both ends.

Does the set have any other input you can try?

If no luck, then I suspect the set has a problem. The price of repair is pretty expensive these days. Unless you can easily solve the problem, it may not be worth it. There are internal adjustments for each color in a TV or monitor, but the color change across the screen is not good.

I would try another input and if still no go, consider getting rid of it.

Component connections, it's even worse in SD where the brightness/contrast is lower. I don't know much about TVs, but I work on electronics and have adjusted TVs before, but there is nothing to adjust in this one.

What model is it? I have a Panasonic TC-17LA1 LCD TV. There are no color controls on the unit. They are only accessible from the remote. I think the remote button is "menu" then a screen comes up with "Picture Adjust" and "Audio Adjust". Picture Adjust has the usual brightness, color, tint, sharpness, etc.

It's a CT27HL14. There are picture adjustments, but the color and tint are so far off it's almost impossible to get it to look right with them. My 12 year old Panasonic Superflat blows the new one away, even when using the progressive scan in HD mode. Maybe they have just gone that far downhill in that many years. It has a Samsung picture tube, a company I cant stand, had I known that I wouldn't have touched it to begin with. I only paid $255 total for it, too much for what the picture looks like. Thing is I look at reviews about the TV and everyone raves about how great it is.

$255! That is a great price. Circuit City has it for about $550. Hope you did not buy a refurb or demo and inherit someone else's problem. You can probably sell it on eBay and make a profit at the price you paid.

I've got an ad coming out later this week. I bought it from a clearance type store that I can't return it to. I should have learned my lesson with buying stuff like that when I bought the JVC DVD recorder and ended up dumping it and losing $150. I guess I'm a slow learner, at least I won't lose that much this time.

I have seen this on a couple of HDTV sets. In one case, it was a bad HDMI cable from a cable company HD DVR to the TV HDMI connector. Had to wiggle the cable and hold it in just the right position to get a good picture.

In another case, it was one of the component video cables wasn't making good contact with one of the component video jacks on the AV receiver. Just needed to push it in a little bit more to get it to work fine all of the time.

Before you spend a lot of time and effort on replacing other hardware, make sure it isn't your cables.

I tried 2 sets of cables. It's the same in SD with the s-video too. I think it's just the TV. I might go to CC tomorrow and see what one there looks like, see if they are all like that or if it's just this one.

Sometimes its the dvd player.

I have a Panasonic Tau, I use an image of an adjustment screen on it to adjust each input. Yep, each input has to be adjusted.

[samijubal]

I checked it out again. It actually looks better in SD with component cables than it does with progressive in HD using the same player and the same connections. I also went and looked at one in CC, it was slightly green, but not like the one I have. They had an actual HD 1080i signal though, the best I can do is 480p.

[handyguy]

There are green with panasonic topics on the board but most have to do with the dvd player. At any rate, the panasonic dvd player/recorders/tvs have image adjustments you can do.

See if you can get your hands on one of the three mainstream calibration DVDs. (Sound & Vision, or Avia Guide to Home theater, or the Joe Kane one). OR, if you cannot, see of you have a DVD which has the THX logo on it, and use the menus to navigate to the THX calibration routine. Then, calibrate the set, including the contrast, brightness, color, tint, and sharpness. Any of these will tell you INSTANTLY if you have a problem with the actual set, or cabling, or source material (like one of the circuits is not firing a color, causing the overemphasis on another color that you are witnessing).

You may have to obtain a simple color filter from a paint store to do the colors properly (usually can be had for free, or for next to nothing).

Someone in another forum mentioned service menus, so I did a search and found out how to get into them. From there it was a piece of cake, just went to tint and adjusted it. All is well it looks fine now.
