Question about Philips 60PP9202 60" Rear Projection HDTV-Ready Television

1 Answer

Replacing Coolent Is it a difficult repair to replace the coolent in the lenses? How much is it to have someone do it verses doing it myself? My pictures convergence lines are blurry or fuzzy. Also I have a yellow hue in the middle of screen. I already replaced the ICs and resistors myself so is the coolent problem harder? Where do I get the coolent? THNX

    I was told that the fuzzy red convergence crosshairs on the adjustment menu meant that the lenses need new coolent. I already replaced the ICs and resistors that cause the convergence issues. I just need to know the symtoms of bad or empty coolent. Another Fixya member says it is a new coolent issue. I found the coolent in a 3 pack for $55 at I also obtained the service manual. It does look extensive. I will try the repair when I can assure the problem is the coolent. I wonder what the cost of the repair is. WB

    Do you mean adjust the focus knob inside the unit? It's not the picture thats fuzzy, it is simpy a "fuzzy red glow" around some red or white edges of pictures. Then in the convergence adjustment mode of the standard user menu the red convergence crosshairs have a 'red fuzzy glow' under them and the multipoint convergence crosshairs are completely red fuzzy glows. I need to pinpoint the problem though for sure. I dont know what new or refilled coupling fluid is suppose to fix.

I have the service manual, and it looks like this is a bit of a job. You also need a special coolant fluid, not water. Still, I can't think why this would need replacement unless it has leaked out or you were replacing the picture tube. Are you sure it's not a focus problem?

    You might want to try and get the set into Convergence Alignment Mode (062597 Status) and check out each gun individually. I can't imagine all 3 CRTs would need new coupling fluid. Again, have you tried adjusting focus? That's pretty easy to do.

  • jsherman Jan 14, 2008

    Yes, there are focus pots mounted in a block accessible from the rear with the panel off. Give that a try first. There are screen adjustment pots on the bottom you should leave alone. It sounds like only your red CRT is affected, so you should only need to adjust the red focus.

    The coupling fluid cools the CRT and also couples the output optically from the CRT faceplate properly to the lens. Since the idea is to cool the CRT, if it's really gone I suspect the CRT would not last long without it and may be damaged.

    If the focus adjustment doesn't work, I'd check the lens and CRT for debris that might be obstructing the image before I'd work on the coupling fluid.

Making a clanging sound started up and smoke came throught the vents, belt came off and liquid was all over

sounds to me someone didn't have the required coolent added to the engine, it has frozen and busted your engine block, waterpump, etc. The smoke is probably steam from the busted heatercore. Expect to replace most everything that is engine coolent related, possibly even the engine if the block has busted.

Most common reason for overheating is 1. low coolent lvl 2. faulty thermostat (stuck closed). 3. Faulty water pump preventing coolent from circulating through engine.

Check coolent lvl in radiator when engine is cool by removing the cap and filling it up till you can see the coolent, replace cap and try. If you have the proper lvl of coolent. Replace your thermostat, which is located under the thermostat housing (right underneith where your top radiator hose connects). Fill with coolent and see if that helps. Next test is to start the car and let it run till it gets to normal operating temp or near (180 to 220 degrees F) Pinch your upper radiator hose and see if you can feel a gush, or flow of water rush through the hose when you release your pinch hold on the hose, (by pinch, I mean to try and totally squeeze the hose together) If you don't feel the rush of coolent through the hose, then your waterpump is faulty. If your car quits overheating, but your heater hoses don't get hot, then they are probably stopped up at the point where they connect to the engine. Its a common area for gunk, rust, and corrosion to build up.

My 1996 Maxima leaks water from what looks like a hose going into the front of the engine block

ok check the hose if its very soft feeling you may need to replace sounds like a coolent hose. also make sure the hose is tight on the block fitting maby the band has worked loose may just need to be tightned, then refill your radiatior with new fluid. you should be fine. remember to do this after the car is completly cool you dont need a coolent burn and it will stay hot awhile so its best to get the hose you need [if you need one] the day before with the coolent, that way you can do it first thing in the morning when its cool. also if green coolent comes out green coolent goes back if orange coolent comes out orange coolent goes back in. never mix those typs of coolents they are not compatible.. you will probily loose all you coolent so drain it at the bottom of radiator before you start. unless you like laying in it to work on the hose. then refill all is well.. i hope this helped you.. also youtube has alot of good videos on radiator type stuff just type in radiator hose replace and you should get alot of videos on how to do it. who knows they may even have one with the same model as your car.. again i hope this helps good luck

Refrigerator not cold enough

check the freezing level, there will be level of the coldness for different levels. check whether you have adjusted it to the highest level or lowest level.
if it is in lowest level then increase the level of it and just have a check, if you still persist the problem then you need to call the technician .

The Coolent which will be present in the backside of the refrigerator has got leaked, the leakage can be due to many reasons like damage in pipes where the coolent is passed to the different parts, due to the opening the refrigerator door for long of time the coolent leakage etc . are some of the reasons for it.
you need to check the amount of coolent present inside the cylinder like container which is present in the backside portion of the refrigerator.
If the amount of coolent present is less the desired amount then the cylinder must be filled with the coolent upto that amount, it will be a bit costly. it is a difficult task you need to call the technician itself ...

Directions on replacing coolent

  1. Must be careful, projection coolent must not get on circuit board. It will short out. You must have a pump to suck coolent out of tv. Use alot of towels to catch dripping fluid.

Convergence Problem?

It's hard to tell for certain, but from what you're describing this sounds like the degaussing mechanism of the TV is either malfunctioning, or that there's some electromagnetic field around that keeps screwing with your TV. This could be caused by speakers, lamps, or any other electrical device. In any case don't hurry to spend 400$ on repair, it's been only three days, and there's a nice chance its not the convergence, or that you'll be able to find someone in your area that won't overcharge you. If there was any device added to the mix around the TV lately, remove it, and try plugging out your TV over night. If turning it off and on a few times won't solve it in the long run(that's the way you make the degauss mechanism work), you should look again into repair options in your area. Good luck
