The easiest way to resolve this is to purchase the convergence board (part number JT21944R) for $261.16. Upon return of the bad board to the place of purchase, a refund of $50 will be processed. This part is available from tritronicsinc.com

Hope this helps,
Dan

My friend has a Phillips RPTV model number 50P8341 and the convergence is messed up and the picture is bowed. Any ideas?


install the convergence repair kit. Its takes 2 STK392-110 Convergence ICs and you will need a few of the 6.8 ohm resistors. You can get the DPTV305 -DPTV345 convergence repair kit which also applies to your model from www.tvrepairworld.com which has the parts and the CD with instructions and the Kit has the STK392-120 ICs which would be a better set of ICs for your model.

I have double image I am looking at array but not


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. 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,Akai2_bing.gif,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

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

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*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

My 50DX20b will not power on...


The convergence amp IC's are bad (STK 392-110) Replace with the Sanyo Type STK 392-120. Also check for burned resistors in that same circuit. Check them with an ohm meter to be sure because sometimes they look OK by appearance .

Convergence is off on jvc av-56wp30


You will need to install a convergence repair kit which contains two Convergence ICs STK392-110 and then the associated resistors as usually a JVC will Need at least 1 or 2 of the resistors when the ICs fail. You can get the kit for your model at the following link which has the IC and all the resistors plus step by step detailed instructions on how to do the repair. This kit fits your model JVC

Colors seperating when unit first powered on


I would suggest to check the following link for a schematic diagram that may be close to your model. I do not think they have changed their design much only the model numbers just to add more features or charge more.
http://www.eserviceinfo.com/equipment_mfg/Hitachi_2.html

You will need to change the convergency STKs to restore the distorted colors. Check the low value resistors, fuse esistors that are connected to the ICs leads.
Those parts are mounted on a heatsink, they have normally 18 to 20 leads depending on their numbers.
Hope this helps.
Good Luck.
