Re: picture problem

You will need the assistance of a servicer,I dont know the age of the set but there is a possibility the picture tube might be going bad based in the description of the symptoms,there is one other possibilty ,that is all the voltages are low because of a bad regulation in the power supply but a servicer will know as soon as he sees the set,ask for an estimate and then make a decision,Is the best We can do without seing the picture.Let Us know if you need more information.

did u mean to adjust the picture setting then go for the following
1 press menu on the remote
2. using down arrow select picture quality and press ok. available options in picture quality and its use is listed below. you can use it according to your preference.

Screen is too dark

with a flashlight at the back of the set often times there is an adjustment you can make WITHOUT having to open the set!!!

look for a little hole in the back of the plastic cabinet labeled SCREEN then with a flat screwdriver holding only the plastic handle, insert it into the hole and SLOWLY rotate until the screen brightens up until it is watchable.

This is compensating for age in the picture tube. you may get a few day or a few more years! of a much better picture.

If you start seeing some thin lines on the screen then back off you have gone too far. Do this adjustment with the brightness and contrast controls on the menu turned up all the way.

it is also safe to play with the focus adjustment right next to the screen if thing seem a little blurry. you will need two people one to watch from a distance for best picture.

The Contrast and Brightness on tv appears to be dark.

If this is a CRT-based TV and it's been played most of the time, you may have a bad picture tube, especially if strong red colors bleed to the right. CRT's dim with use, unlike LCD or plasma. But it could also be trouble in the video circuits - none of this falls into the DIY category, unfortunately. High voltage involved, unless you're comfortable around it and want to try turning up the screen controls inside the TV. If you do, let me know - but "no response at all" from the external adjustments points to a more serious problem.

Green tint I can't seem to fix

Hopefully someone on here has a manual and can tell you exactly where the tint controls are. Also need to try adjusting the color level, turn it clear down so you have a black and white picture.
Is the picture still green over the screen with the color control
set clear down to black and white? If it does, you might
have an issue with the green gun going out or problem in the
circuitry to it.

By the way, the best way to adjust the picture settings on a
tv are to first turn the color control clear down, then adjust
brightness and contrast for best black and white picture, then
bring up the color level to where it should be and adjust the
tint for best red/green ratio.

Adjustable Color Temp. The Adjustable Color Temperature feature lets you adjust the color balance on your TV, depending on the type of light in the room, such as direct sunlight or artificial lighting. On your remote control there should be a button that lets you change the picture mode, IE. Rich, Personnal, Cinema, Sport etc...

Color Adjustments....

well it all depends on where the tv is located to, if it is in a room with little or no light( windows, lamps) you will want you brightness to be a lil lighter hince not makin the picture as dark, and vise versa for light rooms, u'll wanna turn the brightness down a lil bit to accomidate this room, as for the others i'd say a lil over 50% on them, thats how my office tv is set up, hope this helps, jason

Blueand dark when picture should be yellow and gold bright

Well there are many causes for this. In the back of your tv there are three different color projectors. One red, one green, one blue. One or more of them seems to be out of alignment. They can be adjusted but it is recommended to be done by a professional as there are transformers in the back near that area that create the high voltage current needed to run the color guns.

Brightness and volume

The dark picture is a bad capacitor for the screen or drive voltage for the picture tube driver transistors. The other problem of streaking is one of the same. Thats the indication that a capacitors defective . It could in a rare cas ebe a defective or gassy crt as well but 99% of the time when a crt is said to be gassy its nothing more then poor drive to the crt. Good luck
