Philips 55pp53217 i changed the IC's, change the fluid in the CRTs, picture looks so much better now with the exception of the red. which looks a bit blurry. When trying to converge in the menu, both the red and red multi point, i hardly see red to even converge. Is this a focus problem or something else?

No picture. Sound is OK on Philips DPTV345 model 51PW9303/17F


I would check the solder on the Vertical output IC as ofetn the soolder will crack and the CRts will shut down to prevent damageing the CRts when vertical drops out. If the solder looks good I would try replaceing the vertical IC very inexpensive and you can get the vertical IC from www.tvrepairworld.com

You need a new bulb replacement. The owner manual will even instruct you how to change the bulb.

Double Blue Halo Effect and Blurry Blue Picture


thats a problem with the Blue CRTs coolant needing replacement. If you look directly into the blue and green CRTs while its playing you should notice a bunch of crud inside the lens indicating that the coolant needs replacement. You can get the coolant replacement kit for a phillips at the following link which includes the coolant and instructions

Just bought the Philips 9P6034C 60 in. rear projection, used. The picture is a bit hazy. The buyer told us that we just need to "have the guns put to it". Is there a special tuning device that the tv...


Your TV most likely has one of two possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem
  • 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.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


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.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Color


Most likely you have the typical contaminated cooling fluid in 2 of the 3 CRT's. Algae grows in there and over time will block most of the light path making it look yellowish. If this is the case you will have to have a technician drain, clean the CRTs and replace the cooling fluid.

Blury picture, convergance problem


What you're describing is probably contaminated coolant in the crts. Between the outer part of the crt and the lens is a chamber filled with a coolant (ethyl-glycol) which can become contaminated and cause blurred picture. I'd strongly recommend taking this to a shop the procedure for changing these is a bit beyond the layman level.
Remove Crt assembly. Mark the Crt lens position for accurate reasssembly.
Mark the centering ring's postions to make easier realignment and carefully remove lens assembly by removing the four torx screws. Keep Crt assembly vertical so you won't leak the fluid...
Remove the inner lens by carefully prying up on the edge of it.
Dump out the fluid in the sink and wash the face of the Crt and chamber with water to remove all the fungus and crud. Flush the chamber with isopropyl alcohol to kill all the fungus and dry thoroughly.
Reassemble inner lens and outer lens and tighten all four torx screws.
Remove side filler plug and fill chamber with approved new Crt coolant, reinstall and converge.
Repeat this procedure for the other two Crts. It will need this done whether it looks clear or not !! The green and blue Crts in this unit are prone to this failure.
Hope this helps
Bill

Bad picture


there is an inherent problem with philips CRTs...they are the ONLY CRTS on the market that have fluid (Glycol) inside them that have to be changed over time. When they are manufactured, they are filled with glucol and bacteria can get inside with the fluid...this bacteria eventually grows and populates within the CRT and causes it to get cloudy...it only happens with the blue and green ..never the red..cause the red emits UV or IR which kills the bacteria. This could be your problem...or...it could be your high voltage...you can manually turn up the screens on your tubes to brighten each tube individually. Let me know how it comes out.....

Red picture cannot adust with convergence


You have bad CRT Fluid, the green and Blue tube need the fluid changed. This is a messy and possibly dangerous to the tv proposition, you will want to call someone to change the fluid, you will probably spend $450+ for the repair, but it should look pretty good when done, possibly better than it has looked in years.
