Question about Panasonic PT-51HX41 51" Rear Projection Television

2 Answers

Panasonic PT51HX41E Colors are all messed up

I turned on my TV of 7 years and noticed that i see on the top and bottom of the screen double images of the picture. For example if the top half said the word component I would see it in red and green. I tried using fix the convergent option but nothing I do aligns them up through the remote. Any suggestions - whats the repair going to cost? Is it something I can fix or would need a TV repair guy.

Yeah, you could get service to replace convergence IC's and perhaps related resistors for these amplifier circuits, ($250-450);however, if you want save some money do it yourself. Get really familiar with service man mode(remote), invest (if you don't already have) in good small tip soldering iron, solder braid or wick, small gauge rosin core solder(.05), knowledge of resistor color code and a whole lot of patience. I completed this job for less than $100, I purchase two sets STK392-110's because first set was cheap 'knock off' that didn't get me close enough with course service adjustment buy Sanyo. Have fun

You need to change the convergence ic's IC7001,IC7002 = part# STK392-110. Also check for any burnt or discolored resistors nearby. (about a $350 - $500 repair)

DOUBLE IMAGE ON SCREEN. tOP OF PICTURE LOOK LIKE A


That symptoms are due to failure of convergence out ICs in your TV that will be replaced to get correct converge picture on front screen.

There are 2 big black IC mounted on big aluminum heat sink and number would be written on as STKxxx, these 2 ICs will be replaced.

If you want to repair TV by yourself then confirm model number of TV to provide you more info or call local tech to replace said ICs.
Thanks.

Distortion and double imaging


Projection sets have two very common problems.

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. 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 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...

*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

Sone TV Picture not aligned.


This looks like Pincushion problem. nothing you can do. Only a Trained technecian can do this adjustment to reproduce a perfectly aligned image. It requires a pattern Generator and other tools. call the company tech.
