Let your local TV repairman check it. Don't touch anything inside it nor open it.

Can not remove the large spiral bevel gear


The large spiral gear is pressed tightly on the spindle then held in place by a wave washer and retaining ring. After removing the retaining ring and washer, you have to use a press to push the spindle out of the gear.

Check your soldering.

Check the resistors - make sure none are shorted.

Make sure you did not buy fake STK chips...

Toshiba 57h81 green will not focus


Typically this is a convergence problem and can be repair relatively easy. Refer to this video to determine if you truly have a convergence problem. Also make sure you use your TV's original remote to make this adjustment.

Blue wave across screen


Just click below for convergence repair kit;

http://servicemanuals.vstore.ca/

Double images and colors are blurry .Blue,red and yellow wave coming up from the bottom of the screen on the lower left symptom is for busted convergence IC,you must replaced this IC in order that will works better again.STK 392-xxx ICs and it's associated resistor,this resistor automatically change value,can caused truoble even though you change the ICs.If you bring this to a service center they cost you $600 to $700,but if you buy the repair kit you can save more,don't wory it is very easy because there is intallation guide including in the repair kit. Feel free to ask whatever the result... click the link for sample picture guide step by step installation;

Hope this may help;

Strange screen colours


Your degaussing circuit is not fully 'demagnetizing' the picture tube.
You can manually degauss it using a strong magnet, but it's tricky.
With a tool made for demagnetizing you simply hold it close to the center of the picture tube and using a circular motion slowly spiral outward to the outer edge of the tube, pulling the magent further away from the tube at the same time. The same can be done using a strong magnet although the results may not be perfect. You can experiment with a magnet using wiping motions as you bring the magnet closer to and further away from the tube.
