Re: Mode#47LG70 screen blanking LG LCD 47"
Have not tried others but I can if needed? Wouldn't this point to power supply board if the inverters are powered from this board?Leave a comment:

Mode#47LG70 screen blanking LG LCD 47"
Good day all. The referenced TV will cut on fine but as soon as a video source is plugged to ANY HDMI port, the screen's backlight will cut out and then back on and will do this about 10 times then stop for a few seconds then start again. This is not a flashing or strobe effect like I have seen a lot on here addressed. Its like the backlight literally cuts out then back in every half second.
With no video input the TV stays on fine. Where should I start with this one? -

Samsung 60" LED Issue (UN60H6400AFXZA)
Hello everyone. I have a Samsung 60" LED TV Model #-UN60H6400AFXZA. Here is the issue: TV will cut on fine, standby led is fine. No image at all though and no backlights seen at all when TV is cut on. Sound works as well, I can hear when I toggle the menu options it is responding. I have attached some images so hope this helps as I have done no troubleshooting yet. I will test the main filter cap and get back as I need help testing the led output. Thanks for you help here!... -
Re: Seiki Model#-SE55GH01
BudM yes the main fuse is good. I do get a steady 164.5VDC across the main filter caps (3 of them). Still testing the diodes.Leave a comment:

Seiki Model#-SE55GH01
Hey guys. Just wanted to say this forum is an awesome resource for many people. I have a Seiki 55" LED TV with no sign of life what so ever. No Standby LED and pressing power or remote produces nothing. Basic troubleshooting I have done so far: Verified power is hitting the power board but no 5v, 12v or 24v detected. I will post some pics of all the boards soon. I do not see a PSON label on any of the connectors. Main connector going to mainboard has 4 5v pins, 2 12v pins, a few ground pins and a 5VSB and STB pin. I will post pics soon thanks. -
Westinghouse 40" LCD
Please see attached. Where would you start to troubleshoot this tv? As you can see about two thirds of the panel is white and top third is ok. Thanks.... -

Re: Viore 42" LED issue (Not powering on)
I got the logo and backlights AFTER swapping the power board. It worked for literally 10 secs then TV cut itself off. When I tried to cut it on original issue came back. No backlight and no logo. I only got the logo and backlights that 1 time when the new power board was installed.Last edited by cheapshot; 06-02-2014, 09:32 PM.Leave a comment:
