Question about Toshiba REGZA 37RV530 LCD TV

1 Answer

My LCD TV, REGZA 37RV530U, turns on for 2 seconds, screen goes blank for 2 seconds, comes back on for another 2 seconds and then goes completely blank. I can still hear sound when it goes blank. Also, the screen is noticeably darker/dimmer when it turns on and there's a of darker spots/blob near the middle. I thinking it's either the inverter or the power supply board fluctuating power going into the inverter. What do you guys think? I had a problem with the inverter before. I had to replace blown caps with generic ones from radioshack and IC. I looked at the caps and they look fine. the IC looks good as well. I checked the voltage going to the inverter and it was a steady 23.6v. Any ideas?

If you are using a hdmi cable take it off and switch to component cables if the problem goes away keep it that way. Sometimes the hdmi hookups have bugs like this.

Try to do this: Just before the Windows start up screen (after the bios loading) press F8 and log in at safe mode settings. If at this mode you can see your screen change the resolution settings at a lower set. Save and reboot normally. Now try step by step to increase your resolution. In case of a blank screen appears at a new setting, don't do anything; after some seconds the monitor will come back to the previous settings. Save and go on.

In case of a problem or clarification, don't hesitate to post.

Picture & sound go on & off every sec, red light blinks 5 times


helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.
