This is a very common failure on Projection sets. Its called a convergence problem.
You may have one or more of the following symptoms.
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.
No Audio / No Video - Makes Chirping Sounds

RCA rear projection tv picture bowed to middle. Red Green Blue colors have been seperated on screen.


If I had to guess I would say it's either the DLP chip or the prism. Simply put the lamp lights the DLP chip which directs the light into a prism and then onto the TV screen. The prism or prisms are responsible for aligning the colors correctly. The DLP chip is essentially a million little moving mirrors which direct light

If you're at all comfortable with electronics you might want to open the TV up to take a look. You might get lucky and find something obviously wrong with the TV. Sometimes adhesives melt and parts slip out of place. If your DLP chip is blown there isn't much you can do. You're probably right that this would cost a lot to fix and not be worth it.

Picture is bowed at top and bottom picture perfect in middle of screen; colors seperating in corners convergrence is perfect


Projection sets have two very common problems outlined below.

The first common problem is convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. The TV can also shut down when the convergence starts to fail.

Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith, RCA and others.


You can more info and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Conversion problems


What model number. Likely your conversion amplifiers and a resistor or two have gone out. Most Toshiba's use STK392-110 which can be replaced with STK392-120. You always replace both even if only one was bad.

Colors seperating and Screen bowing


The convergence circuit is not working. There are bad solder connections on the sweep board and a small fuse is open. this is not easily done yourself unless you have a technical background but an RCA tech can fix this easily.

Bow tie looking picture with 3d color mis-alignment


you have lost convergence. First thing to check is to see if you are missing the convergence option in the customer setup menu. if you do not have this option then i suggest reading the article in the tips and tricks section entiltled "the fl231 fuse problem" this is a common and sometime easy repair if you do have it then you might need a convergence power board

Pt-47wx49e convergence problem


I just replaced the 2 convergance chips, but it did not seem to fix the problem. I then tested all the resistors that feed the convergence chips anf there was a 2.2 ohm fusable blown. IT was R7050 on mine. That seemed to fix it so that I could adjust all the colors through the convergence 2 screen. There seems to be a slight bow near the bottom when you look at the c2 screen, but not noticable when you are watching a picture. Since I got this broken, I am not sure how perfect it should be.

If anyone can send me the service manual, I would appretiate it. Thanks.

Philips Magnavox 51MP392H Rear Projection Television


are you getting sound, was it moved laterly, did you just get it from somone, did it get wet, does it make clicking noises, was the picture color/ convergence blurring before this, were the colors slowly seperating such as red/blue/green?, did the picture bow on top and bottom or sides prior to tihs, was there anything note worthy prior to the blank screen.

generally its IC convergence problem with the larger philips projection TV's however I need more info on your TV, also size make model # anything you can provide gets us a more narrowed solution.

hope this helps....
