Question about Toshiba Televison & Video

1 Answer

We have a Toshiba 52 inch TV, model # TP50G50, manafactor date on it is July 1997. The picture & the sound went out all at once, do you know if it's a fuse or something more serious? It's hard to haul it anywhere being its so big and we dont own a truck. The power button light still works when you turn it on/off. Can you please help us?

It is a power supply fault. The power supply is a switched mode power supply and supplies 5 volts for the difital logic and high voltages for the high voltage parts of the tv relating to the screen display components. When the high voltage part of the circuit breaks or goes short circuit then the power supply shuts that part down leaving the low voltage rail of 5 volts..hence the standby still working. So... you need to be looking at the power supply board where the mains goes in but be aware of the mains voltages in this area if you arent experienced in electrics. The board will still hold 240v if the power supply has an open circuit load

I got multiple thin colors on the middle of the screen


My 3-year old 52-inch Toshiba flat panel TV (Model # 52RV53U, Serial # AM409000295) developed a display issue (purchased Aug. 2008, manufactured July 2008). Vertical multicolored lines appeared on the screen just left of center. The band of thin vertical bars is 5.5 inches wide. The lines are about 1/16-inch wide. They are stationary, always exactly in same place. They over-ride any other picture on the screen (no transparency). They are there all time even with no video inputs to the TV after the unit is turned on. See picture #1. The TV works well in every other respect, but, obviously, it is annoying to watch the picture with the color band blocking about 1/6 of the picture.

I already swapped out the TCON board with no improvement and replugged the TCON board cables with no improvement.

Most likely it is the flat panel tab bond failure (panel made by Samsung). Further updates will be on my Facebook page.

Have a Toshiba TP50G50 Projection televison with no picture. Have 100 volts to power board


100 volts is too low to power the entire projection TV. Usually with rear projection TVs there are three tubes that create your picture on the screen. To power those tubes, they each require a high voltage (usually around 10,000 volts - yes ten thousand) that is produced by a high-voltage step-up transformer call a 'Tripler' - since it powers all three tubes. This device and the rest of the TV require full utility voltage (120 - 130 volts AC) to properly power the unit. Correct the voltage and try again - is the house / residence voltage like that in each room? IF so, you probably have other issues with devices you probably haven't picked up on.

1997 Toshiba 50 inch tv


Sounds as though you have a filter capacitor bad in the power supply. I strongly suggest you have it checked and repaired soon, before it burns up a transistor or regulator. The cost may be a bit high now, but will escalate to possibly a complete power supply board. If you can repair your own set, check the main power supply filter capacitors. Good luck. I hope this has helped.
