Question about Pioneer PRO-119 60" Rear Projection Television

2 Answers

Convergence problem, lower left corner fixed green gun convergence bows upward

My Pro 119 has just developed a convergence problem with the center fixed convergence green gun. The problem is in the Lower Left corner of the screen. In the convergence mode, the cross hair in that corner is pulled approxemately 2 inches toward the center (all other 8 cross hairs for the green gun are in there proper place) The convergence mode with the remote works in all 9 spots (Center and sides) with the red and blue guns. If I place a piece of paper over the center green gun, cutting off the light, the picture is then OK and the green curls upward in the lower left corner is gone (picture is then off in color, due to the green missing) The rest of the picture is OK with the green convergence, only out in the lower left corner and radiats toward the center of the picture. This is the first trouble I have had on this great Projection TV. It has been powered since I purchased it through a $400 PanaMax/Max 1500 Surge suppressor/line conditioner. Would appreciate any help on this and where would I be able to get parts. I am a retired electrical engineer and have been into the chassis of many TV's in the past and repaired. Built a Heath kit 2001 with all extras in 1980.

    I am the person that posted this problem originally, after 2 years of having the set down I finally got busy and have fixed the problem. I replaced both convergence IC's IC2317 & IC2319 (PN STK-329-110) I did them one at a time. First the IC2317, no change. Then I replaced the IC2319, bingo, then I went to the remote convergence of the Red & Blue guns and reconverged the center cross and 9 outlining cross, and everything is now fine. I checked the powersupply board at the same time, everything looked good, but did touch up a couple joints around the HV transformer. If I have to replace the IC's again, I would go with a -120 or -150 for the higher voltage. Say this recommendation on a form after I had purchased the two IC to do the repair. Everything back together now and watching the big screen again. However was debating about a new HD TV but have decided to hold off, money tight when retired. Hopes this helps someone out there.

You have a componet out of tolerance in the green drive circuits, resistor or capacitor. If you have the service manual you should be able to take some raedings off the test points for the circuit and be able to track it down. I am enclosing a link where you can purchase the service manual for that set for 10.99. They will mail it to you unless you go back to the site and request that they email it to you by clicking on the contact us link. They also offer unlimited free support if you purchase your manual. I am one of their support techs. Hope this helps. Heres the link

Panasonic PT-47WXC43G green ONLY is bowed on bottom and top


Hi,
It still convergence chip problem, check big resistors nearby these chips that would be open or devalued and causing problem, specially in green convergence area, your green tube/ gun is just fine and just not getting convergence output signal to show correct image.
I would suggest to download service manual copy of this tv for small fee from any website and fix the issue with schematics help.
Thanks.

Blue convergence is bowed


The Convergence circuit probably has failed and unless you are familiar with the circuitry I
would suggest getting a professional repair facility. If you are, replace the convergence IC's and also look for any open resistors for the Blue Sub-Yoke

SAME TV(mitsubishi HD1080 series)-- corners of screen are bent


Your TV most likely has a convergence 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 are some photos of convergence problems.

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 will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Bowed flickering green screen, black on bottom


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 projeciton 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.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

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

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

Sudden discoloration, ghosting, bowed horizontal lines in top and bottom of picture


The convergence ICs probably have a cracked solder joint on the foil side of the circuit board. Re-flowing the the solder would help. I will always replace the convergence ICs when doing this job. The labor remains the same and you will have to pay a few extra bucks for the parts. To fix this yourself, you will need to be able to identify the two convergence ICs, have a basic knowledge of electronics and be able to use a soldering iron. You will also have to do an alignment through the service menu.
