The liguid is the coolant for the CRTs. It definately need s coolant or the CRTs will crack. Anywhere the coolant splashed to will cause Board and solder corrosion even if a drop. Its also glycol which is poisonous so be careful if you get any on your hands wash your hands right away. Whats the model of your set?

    Thats a DPTV 335 chassis or similar. Try unplugging one of the CRT Drive circuit boards one at a time then trying power. Replace the previously removed CRT circuit board before removing the next to try repowering. Just be sure to unplug it each time before you remove and replace the CRT boards. There will be a dab of silicone on the neck of the CRT and board but if you wiggle it and pull easially it will come off.

Why is my tv so dark


I would try to clean the lenses with a cleaning product used only for projection lenses.


If this doesn't help your tubes are aging and they will get darker over time.


Hope this gives you something to start with :)

Mitsubishi wd 62527 has very dark picture changed


Clean the small front projection mirror. That mirror can get dust on it and will cause the projected image to appear dull and dim and cleaning that mirror will usually restore the brightness and crisp details in the image.

The colors are separating


If you haven't used the autoconvegence option in the menu screen try that. If not clean the projection lenses inside the TV with qtips and alchohol with the tv on so you can see if the lenses are clean.

I have a shadow on the screen in the bottom right hand corner what could the problem possibly be.


It sounds like something has fallen or crawled into your tv. Unplug unit and remove the panel on the rear bottom. Now remove the upper part of the rear cabinet if you cannot see the problem. You will probably find something on the lense blocking the light. This would be a good time to clean the lenses. Using a soft cloth and windex, spray the cloth then gently clean each lense using a circular motion. Do not wipe until dry as you may scratch the lense. Do not spray the lense as you will cover critical components with corrosive cleaner. Do not push hard or disturb any lense adjustments. Reassemble unit and your tv should look as good as new. Let me know how this works out. hardrocko@hotmail.com .

Got a Hitachi rear projection model # 50ux58b. Kids been playing the Wii and all of a sudden no power. Course nobody knows nothing. You know the story. Anyway Fuse and cap probably need replaced. Any idea...


the three guns that the lenses drive operate at 28kv.
there are very high and dangerous voltages in a tv set.
you can look for the fuse main pc board by the power cord..if it is black,there is a major short.if it is just barely blown,change it.
the fuses are 3ag glass type and just pop in. use a set of rubber gloves and insulated pliers.. tvs are DANGEROUS

Philips Rear projectoion tv picture not clear


no its not true, you can lay them flat to move, it sounds like the convergence is out of whack, download the owners manual and redo the convergence manually for the red and blue, then go back and do the same for the multi point convergence for the red and blue, also if the color looks muted or flat, the projector lenses might need to be cleaned as well as the mirror in side of the unit.... very easy to do, just use caution and DO NOT SPRAY ANY LIQUIDS INSIDE THE UNIT.... spray the cleaning rag outside the unit the wipe off the mirror and lenses....i got this same TV free from craigs list here in pa, put a new mirror in because the original was shattered and re did the convergence and this TV pic is AWSOME.... very crisp and clear...hope this helps you

Cleaning cobwebs from philips rear projection tv model 51PW9363/1


I had the exact same problem and the fix is easy to do. Unplug the TV first of all and wheel it out so you can easily get to all of the rear screws.

  1. Remove the screws from the ventilated back panel (the piece of wood with a bunch of holes in it surrounding the AV connection panel.
  2. Remove the wood panel you just unscrewed.
  3. Remove all screws from the upper plastic case on the back.
  4. Remove the back plastic case carefully. This is a little tricky due to two metal pins that it hangs on. Lift it upwards and you should be able to free it from these pins
  5. At this point you should be able to see the entire workings of the TV, and consequently the massive amount of dust that has accumulated.
  6. Carefully take a vacuum and remove all the cobwebs, taking care not to bump the mirror or the lenses.
  7. First, I used some compressed air to clean off the lenses and then used a clean microfiber towel to remove all the dust from the lenses, the mirror, and the screen on the inside. Make sure the part you are wiping the mirror and lenses off with is free from any dust or dirt or you will risk scratching them.
  8. Reverse the dissasembly process to put the case back together.
  9. I went through the convergance settings at this point and found that they were all out of calibration and as such recalibrated them. Use the mulitpoint calibration for best results.
  10. Enjoy a much cleaner brighter TV!
