Pic will not come on, was going out, then would come back on. Now just volume works and last year I had the Blue and Green tubes replaced. What can I do now, also the standby light flashes all the time?

It means you have Bad Coolant Fuild in the Blue Tube,most of the time it will be the green and blue tubes and it needs to be changed and New Coolant Fuild put in it. Philips is the worlds worst having bad coolant fuild in tubes.

Turns on for 30 sec then goes bright blue and goes back into standby. turn back on it does it agian


This is blue CRT problem in tv as it is rear projection tv that has three CRTs red-green-blue inside to project color picture on front screen.
Blue CRT (tube) will be replaced to fix the issue and it is job of Pro because lots of adjustments are required after replacement of tube.
Local tv repair shop will help you for that.
Thanks

Sony kp51hw40 has green shadows and on edges in pictures and blue flickers on and off, tried all adjustments including screen, focus, and menu??? no luck


The CRTs in this model of TV had a problem with internal leakage. The blue was usually the first to show the symptom (flicker). Because all 3 CRTs are connected to the same high voltage source, when 1 acts up, the other 2 suffer as well. You need to replace the Blue CRT. However, this TV has some age on it... 1 tube will lead to 2 tubes, and 2 tubes to 3... They only last about 7 years. If you love the TV, replace all 3 (about $200 each). I recommend replacing the Red and Blue first, adjusting the geometry and convergence to the original Green. Then replace the Green, adjusting the geometry and convergence to the new Blue and Red.

Pic suddenly went dark, very dark. Images seen are oversaturated. hitachi ultrascan hd is about 8 years old. Help!


I have the same problem. I took the back cover off of the TV and blew all of the dust out and the TV started working again. But this only lasted 2 days. Now the TV is dark again.

Only red tube shows picture, but green & blue are on, just no pic


More likely the problem is the blue and green fluid in the tubes is so cloudy that its distorting the image. Get a fluid kit from www.tvrepairkits.com

A lot of red in pic no matter what we do and tint dose not change anything


As is typical with all Philips projection sets the cooling fluid has become contaminated in the blue and green picture tube assemblies. The red is almost never affected with this as whatever bacterial growth is discoloring the fluid in the blue and green tubes can't seem to survive in red light. The blue and green light is shining up through muddly cooling fluid and that is why the red is predominating. A reputable tv repair shop can pull the tube assemblies and dismantle them and clean and reassemble and refill and do all the necessary adjustments for around $300 to $400.

Picture turned green


It sound like a bad tube there are three tubes red green and blue.
i suspect the blue tube is bad. tubes cost 160.00 plus labor 450.total . sometimes the tubes
can be fixed or the tv tech can adjust the screen voltage on the tube.


good luck thanks jay leadingedgeelectronics.com

Blue Screen


You have a bad blue picture tube. If you replace it the red and green will be weak and probably go sooner than you think. Everytime I had to replace a tube in a sony projo tv i had to replace all 3 picture tubes at the same time. It's very expensive if you don't have any type of warranty coverage.

No Blue


Nope you did it! Its the blue tube. Go to http://www.samsungparts.com and enter your model number and look up the tube. I did one last month for someone at techlore.com Are you the same person? Oh well look it up but do you have the proper equipment to replace this tube, as its very dangerous to handle!! They have a tendency to implode and then explode if not handled right.
