Re: 64" phillips rear projection blue on screen

i would say most probaly that there is fungi in the blue cooling fluid..
replaced the fluid in mine yesterday and now she is 100 percent better.
there are a few online how to's around but the best i have found is this one

as for the darkness a simple tweak of the crt's power can fix this. its the little pot usualy near or connected to the same part as the focus..
but be warned it is very easy to go too far and blow it...

as the tubes get older they alsso get burn in on the face of the crt..
this does not mean that it has to be visible (i have seen some with giant keno numbers on them)
it can be just a nice even patch that will reduce the brightness.

hope that helps

Shows alot of blue image/tv 60 in. rear.....

Sounds like the coolant in the CRTs need to be changed, Blue is always the first to congeal followed by green. Its actually a easier repair. I will post a link where you can get the phillips coolant replacement kit which contains the coolant required and an instructional CD with pictures of the process step by step. Heres the link its listed under the repair kit category.

Red , Green And Blue.

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.

No picture, screen is dark, but audio and the system control is operational

This sounds like the vertical output IC has stopped working. If the vertical pulses are missing at the yokes then the picture shuts down to protect the CRT's from being burned by the intense thin white line through the center of the picture. I have seen many of those TDA vertical output IC's fail.

Darkening tv picture

The Picture tubes(not bulbs) do and probably are weak. There replace should only be done by a trained service person. One reason would be the hI Voltage issues related to the crt's, as these tubes store alot of HI voltage even after its unplugged for a while, and another reason would be that these tube can very easy implode then explode and that wouldnt be a pretty sight. Third would be the alighnment involved after all three tubes are replace. There ba cross hatch generator and alot of time involved with the alighnment. Please seek a pro to assit you when your ready to spend at least 900 TO 1000 bucks. Good Luck
