Hi there - I've got a Phillips mdl # 60PP9753/17 and recently the picture has dulled and has a red tint . I'd consider doing minor repairs (less than $200.00 usd) if replacement parts can be aquired for...


All projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

  • 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.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common 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.

Just replaced burnt out bulb in Infocus 4805 projector. Great picture with new bulb but only black and white. Is this a bulb issue or something else in the projector?


This is most likely the color wheel. When the bulb blows, it can damage the color wheel. The color wheel is a wheel composed of thin layers of colored glass that spins in front of the projected image. It is possible to repair it with super glue, but the best way is to try to find a new one to buy.

I just need to adjust the resolution on this TV. NO ONE at RCA could seem to help me. Thank you.


hi,
did u mean to adjust the picture setting then go for the following
1 press menu on the remote
2. using down arrow select picture quality and press ok. available options in picture quality and its use is listed below. you can use it according to your preference.

of the picture.

When exiting this menu, the Save Personal Picture Preset choice list will

Covergence problems or alingment , its has three colors without alingment please help me!!!


manual convergence should fix the problem if it does not the set most likely either has a bulb burnt out or a bulbs power / focus needs to be adjusted by taking off the panel and finding a 6 screw control panel

...
...

should look like that 3 screws in a row on top of another three screws each of thees control the power and focus of each color this is a somewhat delicate process and is a huge pain on larger tvs that you cannot completely see the picture or color while you are directly under in front of it so I had my gf come in the room and sit across to let me know which color was doing what if you dont have someone you will need to check after each adjustment

now the diagnostic
as i said each screw controls a colors power and focus the focus is used if you see an outline of a color around pictures if everyone looks like a dead jedi with a blue aura around them the blue focus needs to be adjusted and so on for each color if you skies or blue screens seem feint your blue power probably needs to be turned up and so on for each color

if through the course of this you can see the bulbs and notice one is out your probably looking at dealing with the color issue until the time you can purchase a new tv as the cost of the bulb and the technician needed to install it as they are wired to a circuit board and requires technical knowledge and tools


hope this helped

Tv out of foucs


These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

My Sony KDF-60Xs955 rear projection has a blueish green tint on the screen. it is really noticable during darker scenes and is distoring the colors in other pictures. A tech came out and tried to adjust...


this is normally either a color calibration (easy) or a light adjustment(if burnt out very bad)

for the color calibration you want to go into your menu setting and look for the color calibration menu it should give you two cross hairs to align causing a different color yellow red is orange green is blue yellow and so on after ensuring all theese setting are correct your best bet is going to be taking it to or having a television repair man come to you to check the bulbs hopefully if just an adjustment needs to be made cost should be minimal unfortunately if a light is burnt out its usually cheaper to buy a new tv

hope this helps
please leave feedback
thanks

Samsung model number PCL5415R The blue bulb is weak. where can i get one and can I replace it it is a 52inch projection HDTV ready


You may also have a problem with the convergence. There are three color cans that project the image on the screen. A red one, green one and a blue one. The blue one is the one that you should try and adjust. Have you tried to realign the convergence yet? You should be able to go into the menu setting and locate this option is is typically done using the remote. What you will see is some cross marks starting in the center and move to the four coners. When you adjust it you will want to align all three (red, green and blue) crosses where neither color is more prevalent. If you are unable to get the blue can to align with the others, there is a problem with the convergence board. These boards or ICs can be replaced, if you have a repairman fix it your looking at around $250 - $400. If you would like to fix it yourself you can get the parts from...

52 in rca projection 2006 cutting of the top of heads of people


There are manual settings on most projection tv's to adjust the size and to bring the picture down so it is centered on the screen better. Try adjusting the three colors mentioned below first. All projection tv's are pretty similar. If you need to adjust the picture manually, which you should not have to, there are manual knobs behind the front of the tv or at the rear. They should be marked for thier function.

Here is how to adjust the convergence one color at a time.You should be able to get to the convergence screen with your remote. You need to go into the setup screen and read what is on the menu there. It should say how to adjust when you get there.

Convergence- The Auto convergence feature automatically adjusts the TV’s tubes
(this may take several minutes, after which you can make fine adjustments to the
convergence settings); Red convergence displays the Red convergence screen,
allowing you to use the arrow buttons to align the red and green images; Blue
convergence displays the Blue convergence screen, allowing you to use the arrow
buttons to align the blue and green images.

Also this is in the manual for a generic projection tv.

Call 1-877-RCA-HDTV and have your unit’s date of purchase and model/serial number ready.
• A representative will troubleshoot your problem over the phone.
• If the representative determines that you should receive service, they will provide you with the name(s) of the
Authorized Service Center in your area.
• Contact the Service Center and arrange for home or pick up, repair, and return service, provided that your unit is
located within the geographic territory covered by an Authorized Service Center. If not, you must take your unit to the
Service Center location at your own expense, or pay for the cost the Service Center may charge to transport your unit to
and from your home.
• Proof of purchase in the form of a bill of sale or receipted invoice which is evidence that the product is within the
warranty period must be presented to obtain warranty service. For rental fi rms, proof of fi rst rental is also required

Here is a link to rca tv manuals if you don't have one.
You can download them in pdf.

If this is not a help, please give the specific model number.

Picture cut off


No adjustment needed on these LCD projection. Your problem is in your setup menu. Your default is now is set ZOOM. That is why the bottom of the picture is cutting off. Go to Menu, setup and screen size or something close to that.
