Question about Toshiba 57H83 57" Rear Projection HDTV

1 Answer

Toshiba 43 inch projection set

I have a 2003 Toshiba Projection TV. Last weekend while watching the set the screen went into vertical lines and after 1 or 2 minutes went blank. If I left the set off for 1 or 2 hours the picture will come on for 5 minutes then repeat above problem. Any ideas on a fix. Thanks

    Thanks for the quick response! A local repairman wanted to replace a part, don't remember the name, and said it would cost $475 to fix and he would need to take the set to his shop. From your response it sounds like an in-home fix is appropropriate. What do you think?

Possible bad solder connections in convergence circuit or vertical deflection circuit. This happens in alot of equipment. After warm up, expansion of joint pulls connections loose. Recommend not running like this, could cause component failure.

Different color vertical lines on screen Sony KDF-E55A20


Go to the last page of troubleshooting in the manual and perform the system reset procedure. Basically hold the Wega "arrow up" as you manually switch the TV off. It will automatically switch back on and reset. I had only vertical colored lines on the screen, with audio but no response to any remote control functions. The rest worked perfectly.

No picture


Sound like you lost Vertical Deflection.  Youshould not have a line across the screen because this could destroy the threeCRT Red, Green, and Blue (Picture tubes) if left on to long. There is a protection circuit built in to protect your CRT’s.    Check on the PCB-SIGNALboard (Tuner located on this board) transistors Q-206 Collector should be around 1 Volt Base and Emitter 0V. If the voltage atthis point is greater then 5 Volts the Vertical output IC-401 (Mounted on heat sink 7 pin inline IC) is bad, Part # LA7845.  Pin Voltages should be PIN 1= 0V, 2= 34V, 3= 32V, 4= 3V, 5= 3V, 6= 33v, 7= -6V.  Data sheet located at http://pdf1.alldatasheet.com/datasheet-pdf/view/40357/SANYO/LA7845.html

Toshiba 46In HD Rear projection TV Vertical lines on screen


We also have vertical lines with our JVC 62"... turning it off and letting it cool down is the only solution. For us, we know it's a problem with heat. We simply are wits end on fixing it. added two additional fans, a exterior fan to blow heat away from the back of the tv, pulled everything else away, etc.... Anyway, goodluck.

No pic but sound :/


You are having a high voltage problem. Quite possibly in the horizontal deflection. I would check the horizontal output and regulator transistors.
