Orange /yellow picture

Hi,
Ihave a 5yr old phillips 109cm rear projection which the picture has gone a yellowish /orange color. Ive been told that there is an oil inside that needs to be replaced. It is quite expensive to have it done proffessionaly as it is a slow tedious job. Have you got any info on how to do this myself to try and salvage this tele.
Thanks

Hi and welcome to FixYa,

Initially, it would appear that you have two interrelated concerns: discoloration and coolant leak. The discoloration could have been caused by the coolant leaking into one of the small PCboards at the rear end of each tube. Often it would be on the blue tube but there are instances that it also happen on the green. For some reason, the red has very rare incidence of coolant leak. That being said, to address the coolant problem, some ideas you may want to consider/explore:

Procedures Changing Projection TV Coolant that you can try:
  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 **** 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 CRThousing.
  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 **** clean fluid from the bottle and install it into the CRT through the expansion chamber hole. Goreally slow when it is almost full to minimize overflow. Wipe up any overflow immediately. There will be a small air pocket inthe 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.
You may also want to:
  • Clean the mirror
  • Clean the top lenses of the focusing assemblies
  • Focus the CRT's
  • Adjust the convergence
Good luck and Thank you for using FixYa.

Hi this job is very hard to go and being that the tv is old the parts will cost alot i think it would be better to get a new tv because a new lcd tv will last you 100,000 hours so in the long run you wil save your self alot of money down the line cause there is a chance that something else will happen and it might cost more the next time around

I have a Phillips tv. How in the heck do I hook up my coleco vision flashback to it. This is back


Maybe go to RadioShack and bring the cables you need to hook up. Probably an adapter that will hook it to the A/V jacks, the red/yellow/white jacks similar used on video cameras and VHS players.

My tv has gone some orange colour


Try unplugging your tv and anything connected to it - you might want to take a picture first so you have a reference. I would also unplug everything connected to the tv: cable, stereo, etc. Wait a few minutes, then plug in and re-connect everything.

You can also go into your TV's setup menu and adjust the picture settings - try restoring the default settings first.
