have you reched around the new soldering area carefully, check for solder spills or drops in the printed circuit, also another thing to look for is some of those replacement stk do not hold their weight, you might want to take them out and try the old ones to see if you recover tv power.
Hi, thank you for visit fix ya.
Common problems on this tv ( cause no power):
1.- Loose connection between connectors and cool solder around fly back. ( re solder all).
2.- IC vertical output and capacitor in same section ( 100uf, 220uf,3300 uf and 2.2uf ), replace all.
3.- STKs ICs convergence , need be replace ( check any resistor around STKs, for burn or brown color).
----- Try to do step by step; you will repair your tv.
I will be here for any future question.
Good Day, Butchilee,
Sounds like you have patience, hope your TV has some trace left. Hit recommends that you replace the originals with
STK-392-150's and the resistors. Replace said items with care then back down on the screen/ focus controls and gradually bring the screens up until you have pic, adjust focus. Go into customer menu and adjust color down, set brightness to 50%, contrast to 100%. Then go back and adjust the screens for proper, black/white, tracking. AND It's best to double check the soldering connections.
Good Luck, Big Irish.
If one your convergence IC's is bad then you will still see a picture but the colors will not line up, especially around the edges. I have never seen a Toshiba projection set completely lose the picture because of a defective convergence IC. If your vertical output IC has failed or cracked loose then that is exactly what you will see - no picture! The vertical output IC is usually on the same board as the convergence outputs which explains why it worked last time, even if the tech was not 100 percent accurate in knowing exactly what was wrong - he just changed everything. Resolder that vertical output IC and make sure it is getting power. If you still have no picture after that then have a qualified tech look at the set.
I had the same red blinking led problem on my Toshiba Theaterview tv. I resolved by: - Unplugging the tv. - Press several times (3 or 4 times) the tv Power button. - Plug the tv back in and press the Power button once to turn the tv on....tv worked!!!
I've had the problem before and tried unplugging the tv for a couple of days and that had also worked, but I this recent solution seems to be faster. Good luck! Erick
