Ws 55511 convergence lines bowed down at bottom of screen

There are at least two pico fuses in the DM unit along with the caps; DM is large metal box on left as you look from behind.

Blinking green light that does not stop means problem is in DM unit that is not booting up.

If you have questions let me know.

2,2 is the error code for short protection.


The most common reason for this is one of the 2 pico fuses that protect the convergence circuit is blown. Changing the fuses will not help! They are green in color and soldered into the middle circuit board and are F9a04 and F9a05----look like resistors but are 5 amp fuses.

99% chance if one or both are blown---you have to have someone change the STK-393-110 convergence IC that this set uses----the IC can be purchased on Ebay for under 14 dollars and the same seller sells the pico fuses 5 @ 2.95.

The best thing to do here if you or someone you know is able is to unplug the set and look for the fuses---middle board towards the back---there are 5 of them and the two closest to the back of the row are for the convergence IC----If someone checks them (like testing any other fuse) you will know--if either or both is blown--the convergence IC got them.

I have start to finish, step by step instructions and photos of the fuses etc----If you or someone you know can solder and is handy--you may be able to do the repair yourself.

If not, shops usually charge 300-400 for this kind of repair in this set.

LET ME KNOW IF YOU NEED ANY ADVICE or help.

See my reply to your last posting---The set needs The Stk-393-110 and whichever of the two pico fuses is blown replaced--I have instructions AND photos of what the fuses look like.

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device” and “menu” buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

Your TV most likely a convergence 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 are some photos of convergence problems.




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.

SOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Check these two green pico fuses F9A04 and F9A05 to see if they have continuity, if they dont have continuity the Convergence iC and those two picos will need replacement.

Good Day;

Sounds like you have bad Convergence Output IC > 267P155010 > STK393-110, replace and it will correct the problem TV uses only ONE, make sure all resistors look good in the circuit around IC.
Good Luck, big IRISH.

is the front stand by blinking all the time if so u may have a bad DM module , 4 capacitor may be bad , also it may be the convergence ic with 2 pico fuse open 5amp

Solution #1

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.
