We have a for sony kp-51ws510 tv. It turned on and worked ok at first but had bad convergence chips. We replaced the chips on the tv but now the tv will not turn on, it just clicks and shuts off and sometimes a little smoke comes out of the board. what should we do?

The tv have a problems known as a convergence problems,it dead.The tv have any colors lines R,G.B mis alignment,picture have colors shadows or 3D pictures.The tv convergence board the 2 STK convergence ICS and some or it resistors are dead.These parts on the tv convergence board,must be replaced to solved the tv convergence problems.The shop,will cost u $300-350 for parts and labors.

Double picture symptom shows tv got problem with convergence out section and most probably convergence out chips would be replace to fix this issue.
Though its job of qualified tv tech to replace convergence out chips yet I can provide you helpful info if you are handy with electronics stuff repair and can replace parts in circuit board as soldering work is needed with proper tools to repair tv.
Thanks.

this is about a 6 on the skill level of tech you need to be able to solder good and need to have a meter to check various fuses and resistors

Hi,
Remove back cover of tv and on left side thee is D Board that has 2 big black ICs mounted on big aluminum heat sink, these are convergence chips in Sony KP-51WS510 tv.
Below is an exploded view taken from service manual and convergence out chips location is marked with red just to give you an idea.
Hope this info will help you.
Thanks.

Hi,
Convergence chip used in Sony KP-51WS510 part number is as follows..

STK392-560 and Sony part number, 874901908

Available in Part Store.
Thanks.

you have bad convergence chips, 2 of them stk392-570, you must pull the board out and older in the chips, you probably need a tv repairman.

its failure of Convergence Out IC chip and requires replacement.
TV has 2 IC chip in convergence circuit and I would recommend to replace both at same time.
Let me know exact model of Sony 65" TV to provide you more technical info.

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 using the convergence menu. 
Screen is bowed in but stationary.

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 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 includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself. 

Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip 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 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.

Solution #1

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

Solution #2


What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Your tv has a convergence board problem. Two convergence IC's need to be replaced.
