Make	Model	Symptom	Problem	Solution	By
TOSHIBA	1491KAV U15	Inoperative, the LED does not light up.	Shorted q404 (tsh bu 808dfi) and c419 (47uf x 50v) on the capacimeter is fine, but it has to be changed.	Replace q 404 (you can put d2499), and c419. don't forget to test resistors, transistors and horizontal diodes.	RONDINELE Campo Redondo-RN.
TOSHIBA	1483BAV U10	The TV turns on, works normally, and after a few minutes it presents an interference in the image with thin horizontal stripes going up the screen, accompanied by a thin noise like a drill.	Primary power supply capacitor (220uf x 385v) completely depleted.	Replacing the capacitor.	RONDINELE Campo Redondo-RN.

SEMP / TOSHIBA	TODOS	Everyone who uses the bu 808-dfi and it heats up too much, or shorts out	Definitive solution	Use the transistor (2sc 5902) in place of bu 808, retighten the capacitor (c-419) and place a 100 x 63 volt one, add a 1n 4148 diode in parallel with the c-419, connect the katode to the negative of the capacitor and the anode on the positive, remove the resistor r 426 or r 427 and place a 0.47 obms resistor, tsound is no need to place a heat sink	Ademar Videira sc
