Toshiba 40rv525rz shut off while playing xbox. When it shut off i could see a small white line on screen then went black. Tryed to unplug it for 5 minutes and would not turn back on. All it was doing was flashing the lit toshiba emblem up and nothing else! Talked to a couple of people and they told me it sounds like a power supply problem! So opened up the tv and saw that the power supply had a burnt resistor and there was also sut on the backlight inverter so i ordered a new power supply and in

I have an LG 32LC2R TV. I was watching a DVD via that HDMI cable input and the screen just went black. There was power to the unit but no picture. Not sure about sound because I use sound from the DVD unit. I have looked on-line about help, but none really help. Can you give me some advise please? My TV is apart on my desk and I don't see anything out of the ordinary, no burned components etc.

TV turns itself off after about 5 minutes (green light remains on). I can turn off the TV and turn it back on immediately, however, the TV turns itself back off after a few minutes. It started turning off itself off after displaying harizontal shock waves like lines on the screen that got progressively worst. Now there is no line, just powers off. Once turn back on shows great for about 5 minutes then clicks off (no picture or sound) with green light still on.

I have a Westinghouse LTV-32w6HD that has no picture but faint multicolor vertical lines that change according to the input (the lines change as the picture would normally change). I'm on HDMI input but have tried other INPUTs as well with no differences between them. Sound is OK. Remote works. Set powers up normally- just no picture. Where do I start? A schematic with voltages would be nice!


Two possible causes for that problem..1- T-Con board that drives lcd panel (screen) is bad and need to be replaced.2- LCD Panel (screen) itself is bad and replacement may cost you more than tv worth.Schematics in service manua ... Flat Panel Televisions

I have not serviced one of these models before, 26XR9DA. The problem is no Picture Sound OK. The Bachlights come on for about 3 Seconds with Sanyo LOGO visible then go off with the High Voltage inverters powering down. 5 12 and 22 V lines are clean and steady I have changed a few electro caps but this TV seems too new for the common caps problems The B ON pin sits at 3.2 Vs and never changes during startup etc. Im hoping there is a common fault for this symptom.

I have a 2002 Sony KP-57WS500 that occasionly (randomly?) flashes red lines and then goes to a full screen red while giving an electrical "cracking" sound before shutting down. Once shut down, the red power light blinks 8 times in a cycle. Any thoughts? I have unplugged and moved the plug to a different outlet.


Seems like your RED CRT is shorting out or failing. Do you notice any other colors besides just red having problems? The blinking of the red light eight times is a High voltage error. It could be your D board but I'm thinking it is more likely the ... Sony KP-57WS500 57" Rear Projection Television
