Re: [sandbox_91] Phillips Big Screen Fluid Change Help [In reply to] Can't Post

Amazing what can be found by taking the time to "Search Posts"
Limit it to past few months.
It should give you a good idea what's involved. (Presuming you can be bothered to "browse" through them!)

Here's by your model number (No time limit) :

Re: [jts1957] Phillips Big Screen Fluid Change Help [In reply to] Can't Post

 I appreciate your reply. I asked so I could get the "right" and best directions on how do the change. I did search the forum and I found one where he removed the whole tube and coolant container. Is the job too hard for me to try and tackle? How many bottles of coolant do I need? Since the Tv has no other problems other than bad coolant, I didn't want to cause more problems doing it myself. I have found with a good instruction page step by step, I can do almost anything. But I do rely on experts. If there is a step by step instruction list that is the "right" way, please send me the post.
Thanks Again Sherrie

IS THIS A GOOD LIST OF INSTRUCTIONS TO FOLLOW?
Changing Projection TV Coolant
1. Tip the TV set so the expansion chambers are pointed up. The expansion chamber is a small white/clear plastic bulb-like thing That is attached to one side of each of the CRT's up near the top lens. In some TVs, the expansion chambers are already pointed up - In this case you don't have to tip the TV
2. Cover the circuit boards below the CRT's with several paper towels to prevent accidentally spilling any coolant onto the boards. The coolant is corrosive and will destroy the circuit boards. Don't skimp on the paper towels here - they are cheap!!!
3. Remove the four screws that hold on the focusing lens assembly and remove the focusing lens assembly.
4. Note the position of the expansion chamber then remove the expansion chamber. It will need to be reinstalled in basically the same position so remember the position or take a picture if you need to. There is a small o-ring on the neck of the expansion chamber where it threads onto the CRT housing - Don't loose it!
5. Use the baster and tube to suck the fluid out from the hole where the expansion chamber was removed. This hole is fairly small...maybe 5/16" or so.
6. Once most of the fluid is out, remove the four screws that hold on the lens cover plate.
7. Remove the lens cover plate, the lens & the large o-ring. (be gentle with the o-rings!!!)
8. Clean the CRT chamber & lens with denatured alcohol. Use 100% cotton balls so you don't scratch anything.
9. Clean the CRT chamber and lens with distilled water. Again, use 100% cotton balls so you don't scratch anything. This will rinse out the alcohol residue. You need to use distilled water for this so there is no mineral residue.
10. Gently clean the large o-ring with distilled water (don't use the alcohol because it might eat the o-ring) Dry off the o-ring and lightly coat it with 100% pure silicone (not siliconized acrylic caulking or acrylic latex caulking - ONLY USE 100% SILICONE). Use your fingers to rub a thin layer of silicone all over the surface of the o-ring. Then place the o-ring in the groove in the CRT housing.
11. Place the lens in its position on the o-ring.
12. Place the lens cover plate over the lens and install the four screws.
13. Clean your baster and tubing with denatured alcohol then rinse with distilled water.
14. Use the baster and tube to suck clean fluid from the bottle and install it into the CRT through the expansion chamber hole. Go really slow when it is almost full to minimize overflow. Wipe up any overflow immediately. There will be a small air pocket in the CRT when you are done - you will not be able to fill the chamber 100% - This is O.K. Just be sure to fill it as far as possible so the fluid is just up to the edge of the expansion chamber hole.
15. Install the expansion chamber. Be sure to install it in the same position as it was before you removed it. Also be sure that the small o-ring is on the neck of the chamber before you thread it on. The chamber is just plastic so don't over-tighten it or you might damage it. Screw it on as tight as you can go by hand and then give it about 1/8 of a turn with pliers. (you might have to use needle-nose pliers to get a good grip on it.)
16. Place the focusing lens assembly into position and install the four screws.
17. Turn on the TV and check for leaks over the next 20 minutes. Remember, you have not yet removed all the paper towels from inside the TV. Remove these once you know there are no leaks. Other things that should be done after replacing the fluid include...
1. Clean the mirror
2. Clean the top lenses of the focusing assemblies
3. Focus the CRT's
4. Adjust the convergence
Here is a list of things you will need:
1. Turkey baster
2. Vinyl tube
3. Cooling Fluid
4. 100% cotton balls
5. Paper towels
6. Denatured alcohol
7. Distilled water
8. Pliers
9. Screw driver

Re: [sandbox_91] Phillips Big Screen Fluid Change Help [In reply to] Can't Post

I believe it's not quite three bottles (but since they don't sell partial bottles...).
The only step I'd amend would be to make sure "turkey baster" is cleaned very well before reuse (or use two basters - one to remove fluid, one to replace fluid, if not possible to add either directly from bottle via/into a small funnel).
