Vizio E371VA black screen.
The TV turns on the lamps for 15 seconds, lamps go off for 10 seconds and on again and stay on. The logo light stays on, do not blink or change. Voltages coming out of the Power supply board are all checked, there is noticeable variation to the posted voltages on the board. The screen remains black all the time. I disconnected the t-con to see if that makes a difference but not change at all. I connected a video player and nothing changed, there is no sound coming out of it. Power bottom works, I used a flashlight to see if there was a menu hidden on the dark screen and nothing. How can I know... -
Toshiba 32hl67u wont power on
I have this TV and I cant find out what the problem may be. The power botton works, the stand by light and voltage are ok, I checked the lamps and transformers on the inverter board and they are also ok. On the first photo I show 4 boards, 1 is the power board, all caps seem ok, voltages coming out of it are all ok except for one, I have OL on the pin that should read 40v, the rest are all ok, I tried to take a photo but that close it did not work. I also disconnect the t-con board and it did not do anything, still a black screen. On photo 4 it shows there is a steady light on the bottom of board...Last edited by lalin; 08-20-2015, 11:28 AM. -
Re: Have a problem, LED Toshiba 50L4300U with Horizontal flickering lines
I hate when somebody ask for photos or videos and you upload them and they dont even bother to comment after all that effort. -
Re: KDL-50R550A pulsating horizontal blurry lines
That I know horizontal lines are not caused by tcon problems, it may be the tabs on the side next to the inverter board that connect to the lamps or the inverter itself, on the inverter it may be the transformers. Sometimes it may be the logic or main boar but it will never be the tcon board, if you replace it please let me know how it went.Leave a comment:

LCD TV blank screen, stby light stays on.
I have a Polaroid Model FLM-3732, the tv does not turn on, I checked the screen with a flashlight and it is totally dead. I remove the t-con to see if that helps but it did not. The power bottom works to turn the standby light on but it does not turn it off, it remains on. I check the standby voltage and I have 4 volts instead of the 5 volts, would that be the problem, and also, instead of having 12 volts on one cable out of the PSU it reads only 10.7 volts, other voltages are normal, inverter board has voltage as it does the tcon board.Last edited by lalin; 07-02-2015, 11:47 AM. -
Re: Inverter tester using old CFL
I guess you can use the same method on an LCD TV but there are many more lamps, is that practical?Leave a comment:

Re: 2011 rca 46la55r120q led tv - backlight works, no picture, no sound
Is this the best way to know the logic board is working, to test the voltages coming out of it? thanksLeave a comment:

Re: WARNING! bedbugs in laptops and their cases!
Best and easy way to kill bedbugs is to leave the pc, electronic item inside a garbage bag and leave it on the sun or if it is cold leave it outside overnight, bed bugs die fast if expose to extreme heat/cold, dont forget to seal the bags in case they try to run away.Leave a comment:

Home Theater System speakers failure?
I have a home theater player and I tried to play music but only the 2 side speakers play but not the central one, all other speaker work as well, I tried different playback CD, DVDs and for all is the same. Also, I connected the bottom of the center speaker plug and other speaker and it worked, the same when I mix the top plug of the center speaker, it works. They do not work together but with other speakers they do. Any idea what is happening? thanks -
