Is it a LCD or a CRT Phillips TV.
If LCD - could be the lamp just getting old (lot of hours on lamp). Could find the model # of the TV and do a Google search of the TV Model # to find a replacement lamp. If its an older CRT Projection TV the tubes may be getting old and unable to illuminate/glow as they used too! Much like a old set of headlamps on a car.
Replace the coolant in the CRts a very common problem with phillips. The colors will get very dim and red will become domintae as red seldom needs replacement where as blue and green get congealed and the set will get dim hard to focus and you will see a glowing around green and blue objects. Heres a link to the coolant kit for a phillips which contains the replacement coolant and step by step instructions on CD with pictures on how to replace the coolant. http://servicemanuals.vstore.ca/product_info.php/pName/phillips-crt-coolant-replacement-kit/cName/repair-kits
The coolant needs to be changed in the CRTs ( picture tubes) this is a very common problem with all phillips and magnavox rear projections. Changing the coolant will restore the color and brightness and stop the halo effect. You can get the phillips CRT coolant kit at the following link and it includes all the coolant and the step by step instruction CD with pictures. Its actually a fairly easy job. Heres the link its listed under the repair Kit category. http://servicemanuals.vstore.ca/
One of the most common faults with the phillips rear projections is the coolant in the tubes. That can and will make the picture very dim and can cause the brightness and focus controls not to have much affect over it. Please respond to this same post with your model number and I will check to see if their are any other items that could cause that symptom.
That model is famous for having bacterial contamination in the CRT coolant causeing halos, and dim pictures with bad overall color issues. You can look into the lens of the CRTs when the set is laying and if the coolant looks cloudy or has any growth there you will notice it right away, and changing the coolant will restore color, clarity and brightness.
Heres the best way to set a phillips screen controls. Go into the picture controls and set picture or contrast to roughly 75%, then set brightness to 50% and then set the color level completely off. Then adjust the screen with the 3 color controls untill you recieve the best black and white picture as possible. If you are unable to achieve a good black and white picture change the coolant in the green and blue tubes. But if you can get a good black and white picture stop there then turn your color level back up and the picture should be correct. Let me know if you need further assistance.
