Re: Samsung PNC7000 HDMI and Component inputs do not work

It is set on rgb but now that you mention it you're right. Component does get a signal but it's a mix of colors and lines. I can get sound through that one but not a clear picture. I've also tried a few different sources through component to rule out any cable issues. PVR and 360 both do this.

Re: Samsung PNC7000 HDMI and Component inputs do not work

Well it doesn't see HDMI and component but AV/RCA still works as does the co ax cable. So as of now I am running those until I can fix the HDMI. When I test to see if a signal will work I switch between the 360, wii u and the cable box. As for the update the flash drive is Fat32 and I have the TVlausic files unzipped to the root of the drive as the instructions state.

Re: Samsung PNC7000 HDMI and Component inputs do not work

I've got a PVR, Xbox 360 and a Wii U going to HDMI. Hooked up to HDMI 3, 4 and 2 respectively. I tried to update it via usb but that didn't work. the TV did not recognize an update on the flash drive. I am guessing because it is the same version that is already on the TV? I've had trouble in the past getting the ethernet port to work on this TV. Perhaps that was a symptom of a sick Main board?

Re: Samsung PNC7000 HDMI and Component inputs do not work

It isn't hooked up to the net for auto updates and I don't believe there has been any updates for this model for quite some time. But perhaps I could try to install the latest one again and see if that would do anything.

Hi forum,
I am having an issue with the TV not being able to recognize HDMI and Component. The TV can recognize that there is something plugged into those ports as they will light up as select able in the source menu. However when selecting an input I have a blank screen and a message that says no signal. I have reset my TV back to factory settings and I have tried leaving it unplugged for hours and the hooking everything back up. I did get a signal for about five minutes after the first time I unplugged the tv but that was it. I am thinking it is something with the Main Board but wanted...

Re: Sharp LC-70LE650U Will not turn on

Yeah I did check those but they didn't seem to line up with my issue. However I was able to determine that it was a panel fault. Thanks for the response.

Hey Gang,
I bought this one second hand but I am now thinking I got a dud. I've got an error code of 2 slow then 5 fast blinking lights on the stand by. I've checked to see if the main board is getting 5 volts and that checks out. I unplugged the tcon board and it now powers up. However if this is the case i've heard I may have a bad panel and not a bad tcon board? Any help in troubleshooting would be greatly appreciated.
Cheers.

Re: Haier L39B2180 Will not turn on

Here's one I took before I took it apart to examine the panel. A little close but hopefully enough to give you guys an idea? I have the power unattached in this photo.
Cheers...

It's just a cheapo TV but I am trying to teach myself how to fix these things. The standby light is on but the TV will not turn on no matter what. I have already replaced the main board and the power board on this TV but it will still not turn on. I've checked the panel and it seems fine. any ideas where to look next? Any help would be greatly appreciated.
Thank you

Re: LG 50PA6500 - Sound no Picture

Does anyone have the Y buffer boards for this TV? Or know a good place to check? I can't seem to find them anywhere. Cheers.
