20 Most Recent Philips Magnavox 55P9271 55" Rear Projection Television Questions & Answers


You don't, probably. Sorry, but this is a truth. These large projo's have become nearly extinct, and if you call a service man he might hang up on you. I won't work on them any more because parts are nearly unvailable as are solutions from the factory. It's old enough you'll do yourself a favor is you rid yourself of it and buy a newer flat screen TV.

Hello
As far as picture is OK, there must be sound output from the TV. If not, first check its speaker for open voice coil. You can chek it either with the help of a mutimeter of with a mere torch cell. If the speker is Ok, sound out put IC may got damaged. To confirm this, just take the audio out socket ant the TV and get it connected to an other audio output source, like amplifier or so, and check whether the sound comes fro it or not. If yes, it is clear that the audio output IC inside your TV is damged. It s part number is giver in its schematic manual as [9338 466 60682]. This is the part number given to that IC by Philips. The actual number may be somewhat TDA...... series. It is a replacable part, and can be located at the sound output section inside your TV. You can get it from authorised spare part shops of Philips, bu giving the part number I've given above.
If there is no sound output from the external audio device as we connected before, the sound detection section inside your TV has some fault and it is very difficult o locate, and must have most modern testing equipments, as well as the schematic diagram of your TV. The technician must have very experienced, and familier with handling philips sets, otherwise he may get things worse. If the second mentioned is the condition of your Philips set, it is very best for you to get it repaired by authorised service centers of Philips only.
OK.

If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

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. Repair kits with instructions are also avail from www.TvRepairKits.com

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.

convergence is out of line.

The flyback transformer is most likley arcing. It is high voltage so eventually the set will shut down and not power up again untill the transformer is replaced. However those flybacks for that model are very hard to find.

I would say your small signal module is bad. This is the board with the convergence ICs. Have a tech or yourself pull the board out and replace the ICs and some resistors. Checkout TVREPAIRKITS.com. They will have your model and its symptoms. Hope to guide you in the right direction!

The frame around the screen just pops off. Unscrew the plastic holders from the chassis frame and the screen will come off allowing you to clean everything inside easily. The "2" thin screens are easily cleaned and put back on easily also. Don't do what I did and think the screens go into the front slot of your plastic brace, they slide easily into the wider slot. You'll also be able to clean the dust from the reflector and guns with Windex. Much better picture after wards, trust me. You would be surprised how much dust may have accumulated on the lenses.

try to check the cables. it might be broken or not fitted well

Philips Magnavox... | Answered on Aug 14, 2009


This TV probably needs the convergence amp IC's replaced. When they go bad the TV will not turn on.Call a good TV Tech and tell him you want the IC's upgraded to STK 392-150 instead of the original STK 392-120 and check all resistors in the circuit for proper value. They could be burned or open.
