Question about Philips Magnavox 9P6034C 60" Rear Projection Television

1 Answer

Picture tube I have a 28 inch Magnavox tv set about 8 years old.When the set is first turned on there is no picture but I have sound. If I tilt the set just a little or hit it lightly the picture will return but not for long. When the set is on for 20 minutes the picture may stay on for over 2 hours or more. All connections in the back are nice and tight. Have any idea whats going on? Don Roberts

Re: picture tube

It has a bad solder joint. TV's use cheap, one sided circuit boards which don't solder as well and with all the hot and sometimes heavy parts on the board, it is common to have bad solder joints. Especially on the newer ones have have switched to the mandated lead-free type solders. A tech needs to resolder the circuit board using an eagle eye to spy out the bad joint.
Hope Ya Fix it!

I have an approxiamtely 8 yr old Magnavox 50 inch DLP t.v and when you turn it on, you can hear it power on but there is no picture. Trying to figure out whether its something that can be repaired and...

I am familiar with this model, if 8 years old do not invest any money in it as most parts are no longer available from Philips.

Saw a lot of them when only a few years old get junked.

This problems,very common in LCD tv,after the tv was in used about a year or two.The new technalogy LCD tv don't handle heat very well,not like the old CRT Tube Tvs.The power supply board tend to have bad capacitors componnents leakage,that bulges up it top or puff up gases escape,that why it take times or couples pushes to the power botton to turn the tv on.U know basic electronic's,and have soldering tools and solders?Take the tv aparts,check for these bad capacitors,that bulges,puff up in the power supply board and replaced them,than ur power will work normal again.Or tries Websites like, to buy a whole refurbish power supply board for the replacement.

KP53S35 when tv turned on picture was

You TV has a bad CRT, a red CRT by the sounds of it. This TV is rather old, perhaps 11-13 years of age? Your TV has given you many years of service and I do applaud you for the care you have given it and the TV for it’s reliable in your home. The trouble you face with a rear projection CRT set of this age is that you can’t just change 1 CRT tube and expect it to be reliable and produce a good picture. All 3 tubes should be replaced, as they have all aged the same. The lives of these tubes are only about 7 years. A tube is not any easy or inexpensive repair on any RPJ TV. When you are faced with the cost of 3 tubes, which may not even be available in the market place… You should consider retiring this old friend and keep the manufacture in mind as you make a new purchase.

Picture tube fluid

Magnavox are good at fluid breaking down especially blue and sometimes red. Yes you would have to be very carefull not to waste on boards, because of set CRT's are tilt this mean when you open it will start to leak. The best bet if you are willing to try yourself is to prop up set somehow to make crt's level and when you take lense off you can look underneath and open the bottom lense cover up and expose the old crt fluid and then you will need some type of suction pump to suck out the old fluid. Once you have old fluid out then you can clean inside crt and make sure you clean good. Then replace with new fluid and go in reverse and clean all that touches crt. Hope this helps!

Green dot in middile of my screen

The green dot in the center sounds like a burn mark on one or more of the picture tubes inside the set, and the curved lines are telling me that you have a problem in the convergence circuits. The blue haze around everything white tells me you either have a lot of dust build up on the lens over the CRTs, or your picture tube(s) are very weak. If this set is over about 12 years old, I would replace it. I doubt if you will be able to get the green dot out of the picture without changing the tubes which would be VERY expensive.
