I replaced the STK chips and 3 fuses per the research I did on the convergence and blinking red light problem. Plugged all back in and had convergence issues and hor - vert was off so I tried to adjust...


Make sure you didn't bridge anything, knock anything off the deflection board you shouldn't have. All the resistor values on both sides of the STK match up, and most importantly Labeled all your plugs properly and placed them in the right spot, because if they are switched, you'll get a convergence issue. Make sure the fuses are still good too and that all the terminals that all the plugs go into have good solder joints.
Also, there is a voltage divider.
Make sure that none of the wires got loosened when you pulled this plug. (Particularly the ground wire) Let me know!

My Sansung HL-S4266W just shut off one evening while watching. It had all 3 lights blinking and it had been over 3 years since buying the tv. I replaced the bulb, nothing changed the tv would still turn on...


this could be the color engine or a power supply problem. My suggestion is to not put anymore money into this tv, its an old technology and you will be replacing parts for it every 3 or so years. eventially the parts will not be able to be found. Go get a new tv, save yourself money and headaches.

Problem with toshiba 65H84


Good Day, mowattearl;

The most common with this TOS TV is the failure of the convergence IC's, but rebooting, resetting first, unplug TV from wall for 3-5 minutes then plug back into wall. The "conv" IC's are STK's, large black devices mounted to a large heat sink on the verticle.

Good luck, big IRISH.

No Picture.


I have the same TV, your projection bulb has quit/failed.

A loud pop was heard and the picture has gone followed by a red led fault light clicking on and off.

if your tv is less than 1 year old, and you registered it with Toshiba, you could qualify for a free replacement.

otherwise expect to pay 200.00 for a new bulb from Toshiba.

only good thing is you can replace it yourself, only tool needed is a phillips screwdriver.

you can check EbaY for prices less than 175.00 to 150.00
i am on my 3rd bulb within 4 years....

good luck!

Picture getting darker


The tv has a room light sensor,
shine a bright light at it , does picture get brighter?
other wise when it is cool open the bulb door , is it coated or blackened, Don't touch bulb at all.

and a heavy covering of dust on internal mirrors will cause the same effect.
you will need help to clean it.

No picture, sound and flashing red power light...


Pull off the back pressboard. At the bottom left hand corner is the power cord that attaches to the power supply board. There is a white plug that attaches directly to the power cord. With the TV power off, pull this white plug up to disconnect. Then push it back in. Then plug your TV back in and press the power button on the front of the TV. I just did this and it is working fine.
