Yes look for www.bluestar-online.com and check your set and make sure it's the stk392-110. If you can solder you can carefully change it. I would replace all, you may have 2 or 3 in there. Also make sure you don't bridge the pins. Meaning soldering 2 pins together, just be careful. Unplug set and be careful of unscrewing board.

No picture, high voltage cable sparks at left tube/gun at turn on


It sounds like you have a shorted picture tube.
You should call a good TV Tech to confirm this and get an estimate.

Toshiba 65H80 has yellow hue.


Check you HD inputs or source. Sounds like the red stream is missing; maybe a loose cable.

TV made a very loud pop and shut off. When trying to turn it on again, just get a buzzing sound.


Sounds like you blew the horizontal transister in the CRT's high voltage circuit. It's common with tv's that are old or full of dust on the inside.

Sound but no picture


loss of picture with sound ..loss of picture could one of many problems.. these units have serval specal fuses that a tech would need to check. loss of high voltage is a possibility. i would think this would be worth getting a tech to check out, the fact you still have sound may be a positive,

No Picture


Rarely picture tube also shows the same symptom. High pitch sound is due to through deflection area LOT power supply is loaded. Compulsary horizontal output transister short. From your statement i think Lot puncture takes place. Change LOT and horizontal output transister and check tv is now working.

Red drained out of picture


The red transister on the CRT socket could be at fault. there is 3 transisters on the socket check for the voltages on all 3. If the red is high unplug the socket and see if it normal if not the transister or circuit feeding has a short. If low the same case seneral applies and a resistor feeding the transister is defective or the transister itself is at fault
