    I have the same convergence problems, concave screen top and bottom, colors out of alignment on sides, and convergence doesn't work.  I replaced the STK IC's and still have the same problem.  Any other suggestions?

You didnt replace the STK's? You must replace the convergance IC's or you will continue to have this problem.

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, pico fuses, etc. Everything you need to fix it yourself. Its an easy fix.

Convergence repair kit used but problem is worse


did you check and replace the two pico fuses on the G board and also the six pico fuses on the D board? If so double check the solder often a pins mounting ring will lift up during the removal and prevent solder connection when doing the install.

What are the specific pico fuses for my RPTV


The amperage is marked on the board right next to them--likely if they go to the convergence circuit they will be marked 5a or 5 amp.

Usually but not always there are more at the convergence chips.

I presume you did not look closely at the board where the two you found are---Sony marks everything.

Hi,I have sony projection tv KP-57WS510 every subject apears threeple with colorful reflection.What to do? Thanks,Kris


You will have to install a convergence repair kit which will consist of both convergence ICs and the 8 associated pico fuses and the 4.7 ohm resistors will also need to be checked. Your model uses the Sony type 1 convergence kit. If you want to know where you get one they are available from www.tvrepairworld.com they do include the parts and the CD with repair instructions.

Tv won't turn on. A clicking noise. stand by light flashes and then nothing.


Hi qss7.

I had a similar problem with my 42 in Philips LCD HDTV. I may have the solution to your problem.


Here was MY problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.


Here are some options for you to consider.


1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)

Remember, TVs CONTAIN HIGH VOLTAGE AND CAN KILL YOU! Do this at your own risk.

2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. They can be found online. I would definitely shop around though.


3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.


This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It will, at the very least, give you a general idea of the process. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem.


Hope this helps.

If you have any questions for me, please comment on this page. I will be happy to assist you to the best of my ability. Thanks for using Fixya.

Sony kp-57ws510 no power, standby on


Remove the rear cover and look at the board on the left hand side. It's the G board. It has the power cord going to it. Remove this board and on the it you should, with some effort, find D6116 and D6301 diodes. These just need to be heated up to re-melt the solder and then re-assembled. This worked for me anyways.

Tripe image, blue, red and green color on image, not focus


you will need to replace the two STK392-560 ICs and also check the 4.7 ohm 1/2 watt resistors and the six 3.5 amp pico fuses.

Flashing light


Video output IC on either the CR, CG or CB pcb boards is most likely the problem or the A board is defective. I would try the video output on the CR, CG and CB boards first.

Pico fuse


They are usually 3.5 amp picos depending on what circuit they are in. If you go to this link and leave a email with your model number and pico number such as PS321 they will tell you which rating you need and they have all picos for sonys instock.

Sony kp-57ws510


test your power supply output voltages, make sure the step down transformers are not leaking high voltage into the dc circuits. always start at the basics then work your way up or out. the most common problem for these late model tv's is power supply they just dont use quality parts anymore. in older tv's you could hear the high voltage arcs, snap today its rare for that to happen. I have a 32 inch LCD here now that actually blew a 1500 pico farad capacitor with no noise. that amazes me thats a pretty good sized capacitor, and they usually make some noise when they blow the top right off of them.
