Question about Philips Magnavox 9P6034C 60" Rear Projection Television

Open Question

Power light comes on, but no picture or sound

I recently changes the fluid for my CRTs. After changing the fluid, set powered on but needed converging. I attempted to use my remote to access the menu function but couldn't access the menu. After a day or so, the set stopped coming on completely, the power light comes on but nothing else. I reopened the set to see if I had put a wire back incorrectly, but didnt see where that was the case. The only wires I have that are of any question are the ones that connect to 1896 and 1895 located on the Blue CRT board, does anyone know where they connect, I have the scematics but it doesnt tell what they connect to. I've read on other forums where it could be a bad resistor and that I could check them with a digital oltimeter, but I've never used one before and need some laymans explanation on how to use it. I have already tried to contact a repair man to help with diagnosing the problem but have been told that my problem culdnt be dianosed with the $40 diagnostic fee, (which sounds asinine to me), any help would be greatly appreciated.

SOURCE: need help with projection tv

usually the low voltages are attributed to a capacitor that is not performing right under load. however the only way to diagnose the capacitors is in circuit with an ESR meter, those are very exspensive unless you purchase a kit and put it together yourself. I know the following link has the ESR meter kit that needs to be assembled for a reasonable price. You may want to consider getting one, the other alternative is buying a capacitance meter and removing each capacitor from circuit and checking them. here is the link that may be your best bet they do offer free tech support as well.

time for some old fashioned trouble shooting. first divide the issues... the remote not working could possibly be a connection issue.
second you can do a soft reset ... unplug the tv for about four hours.

third is to check for cold solder joints. that requires first smacking the tv (yep pretty old fashioned test). if anything changes you need to localize where the problem is.

You need to be EXTREMELY CAREFUL for this next part. power on the tv and tap components on the circuit board gently with a non conducting item. even a hollow pen would do... or something plastic.

Be aware that you are dealing with electricity so be very careful with that.

any changes on the screen as you tap components indicate most likely bad solder joints... after you have unplugged the set resolder those components.

also inspect by feel the capacitors on the circuit board .... feel for rounded tops. any you find need replacement... not the values of the component as well as the orientation of them.

I will stress again... when you are testing for bad solder joints be aware that it is electricity you are dealing with and it has the potential to kill you.

Soldering or bad IC chips...

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....


  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

Power clicks on and red power light flashes but no picture


The problem might come from the fuse inside was blow out. if you have a multimeter then open the rear cover. The fuse lays near the power cord. Take it out and use Ohm meter to check it connectivity. If it is no connectivity meaning the fuse was blow out. Replace a new one with the same value (Ampere and Voltage). If it does have connectivity, the problem needs technician to find out as it relates to many parts on the circuit board.

Toshiba 65H14 is all green... Tint doesn't change it..


As TVs age, the rate at which the CRTs begin to decline in terms of light output increases. If you go into the customer menu and adjust the color setting to zero. ( no color) observe the image. Is it good gray scale? Or, is the image still green tinted? If so, its definitely a problem with the CRTs( picture tubes) You may need to just re-adjust the screen settings for the CRTs or it may be more serious, a CRT may be bad. Replacing the CRT is a job for an expert and will cost $500-700.

Mitsubishi WS 55807 TV


2 common things that cuase this problem. The first is a fluid leak and I think of this first because you had a audio problem and now you have a dead set. To look for a fluid leak take the front off the set and look on the boards in the bottom of the set with a flashlight for fluid or corrosion. The second problem would be the convergence circuit shorted out. To check for this you will need to be able to use a meter. There are 2 pico fuses (F9A04, and F9A05) If one of these are open you will need to change the stk's and the blown fuse. If you donot have a fluid leak and cannot find the fluids, you can post a picture of the boards inside and i will circile them for you. Let me know if you need more help!

Ballast / Power board


Hello Kreed13,
As I mentioned this TV doesn't use ballast(s), it user CRTs and the time when you need to change one is if the picture looks out of focus of one of the colors.
You might not even need to change it, if it powers up and you can see it lighting up. These CRTs use a liquid coolant inside to keep them cool, that liquids becomes contaminated over the years and will affect the quality of the picture.
This website has a very good info on how to do it.
Why do you think you need to change the CRTs?

Picture mode changes to zoom by itself


It sounds like an eeprom issue. But you can try to reset the set. Turn the set off by the main power on the set. wait a minute or two then together push both the main power button and the standby power button. This should resett the tv. If that doesnt work you will need service as the zoom and the various modes are all controled by the eeprom. Only hold the two buttons for a second. sometimes you will hear the crts discharge while resetting.Hope this helps

Powers on, audio works, no video at all


First, need to narrow down the problem. Did you perhaps change the input source? To this point, change the input source, there should be text on screen that indicates what source is selected.....do you see this? Change the volume....do you see the volume level bar on the screen?
