Distorted upper third of tv what to do to fix may just be convergence board. How hard is it for a non electronics person to install a new convergence board

if your picture looks 3d it is convergence problem.

This is a do it yourself repair if you have some skill.

I will tell you what you need and have start to finish, step by step instructions for this repair along with photos, and source for parts needed(parts cost will be under 30 dollars).

reply here if I can help.

youv'e answered your own question, the convergence
isn't working needs chips to correct

You need the convergence board reworked. You may try www.TvRepairKits.com. This set may be to old for this website. I would suggest looking at Union Electronics for a replacement board. Call 1 800 648 6657. For safety sakes find a TV technician or or an electrician to install this for you! Thanks for asking!

My 9 years old Mitsubishi WS-55857 had the same problem (distorted pictures) for couple of months and I was about to buy a new plasma TV. But, I found TvRepairKits.com and I decided to give a try before buying a new TV. I received a convergence repair kit in two days with web site info for detailed instructions with many picutres to explain the process. When I had questions and Ed was very prompt to answer my questions thru the e-mail. I never done solding before, but I am moderate handy person. I spent less than $100 and three hours and my TV picutre looks stunning. I went thru advanced convergence process after I repalced the convergence chips and replaced RCA video cable with better quality and my TV picture looks as good as brand new. Thansk ED for your help!

Yes, this problem can be fixed if you are handy with electronics stuff repair and can solder parts in circuit board easily with proper tools.
Replace convergence out ICs to get converge picture.
Let me know exact model number and brand of your TV for further info as question shows its Sony KP-51HW40 tv.

There are two common problems with Projection TV sets. Problem #1) Convergence Symptoms:

• Screen Looks 3D
• Colors wont align
• Video may look distorted

Problem #2 CRT Fluid has clouded over. Symtoms

• Dull looking video
• White looking video
• Halos around objects
• Red/Orange looking video

You can see some examples and find a fix here...

SOLUTION http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

It calls convergence problem due to failure of convergence output ICs.
If you want to repair it at your own, let me know if you have basic electronics knowledge and little experience to guide you more.

Hi,

Hitachi Convergence

Check out the Convergence Gallery. If you see the colored outlines or color shading as in the Gallery, you have a convergence problem.

The repair for a Hitachi requires the replacement of the defective IC or ICs and any damaged or smoked resistors. Some models don't have a separate convergence board and the board is not usually available for the ones that do have a separate convergence board. Usually there is little alignment required after the repair. If you play with all the adjustments before the fix, hours may be spent re-aligning.

If you change the original ICs with substitute "new and improved" parts that are talked about in the blogs, you will probably create problems. Use the original ICs and resistors.

Don't monkey with it.

This is a delicate and difficult repair. If not done by someone with some electronic repair experience, the TV will likely end up as junk or cost considerably more for a tech to fix the damage done.

If you live in Calgary, call me. If elsewhere, find a competent tech.

You have a convergence problem. Here are some of the most common symptoms. 

Screen looks 3D
One or more colors can't be adjusted when when using the convergence menu. 
Screen is bowed in but stationary.

Solution: 
You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit inlcludes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself. Its an easy fix. 

The T.V. has a problem on the convergence panel Bd. Check each of the resistors near each regulator transistor. You can send the panel to P.T.S. Electronics in Indiana for repair. Call 1-800-844-7871 and they can repair it for you.
