Color loss (but onscreen displays in color) - DIY repair?
My Philips 32PT5441/37 32"TV abruptly shows only B&W (whether showing cable TV, DVD movies, with same problem even using front A/V inputs); sound, performance and picture quality otherwise fine.
Onscreen displays still show color;
MY MAIN QUESTION IS:
Should I open up the cabinet (properly grounded, electrician's tools/safety techniques, etc) and remove a video card somewhere and pop in a replacement?
If so, what do I need to order?
Thanks in advance
Re: Color loss (but onscreen displays in color) - DIY...
Your description was great, thank you
there is only 1 hope for you on this one, intermittent color is a touf one, tap on the board with wooden or plastic handel see if you can make the color come and go that way, if so you have a intermittent break in the board, my guess is by one of the big ic chips on the board. if not able to make the problem act up with the taping then you have to look at the croma section and color oscillator section , this is not easy needs skiz and a scope and a little know how. depending on what they need for time a shop would charge 100-210 to fix this kind of problem. sorry this is not what you wanted to hear but is one of the tufer problem to fix on a tv.

try a dvd into input one on the tv.if this shows
good with no color problems.then call the
cable co.if you have another tv check the signal with that tv.if the cable is good then
suspect the tuner in the tv.
Probable causes 1) Magnetic field disturbance from near by equipments. eg. Audio Speakers. 2) It might also caused by shifting TV position 3) the degaussing might be faulty. Demagnetizing the set will resolve the problem.
Ok I know I just made a comment but guess what... heres the solution!!!!!!! I was sooo mad that I went and started playing with the cables and got it working. You have to plug in white to white, yellow to green and red to blue on the back of the DVD player and match up the colors on the back of the tv. And it plays in color!! Hope this works for you too!
There some thing that you had done to get black and white on your tv with the dvd ,check your connections.if the connections are properly connected then the tv could be having a problem in the video input, have a tech look at it.
