HDTV goes blank when connected to Fios HD-DVR or Fios DTV recvr.


If you can first connect the Fios box via component and that will rectify the issue and still allow HD. HDMI is funny, if there is anykind of communication issues between the TV or the Fios box you see what happens. You might also call Samsung to see if there is ANY firmware/software updated for your TV specifically to fix such an issue with the Fios/Mortorola connection. If there isn't then the issue is the cable box since the TV works ok on HDMI with other devices.

TV screen goes blank but power stays on


Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

What can I buy / replace to fix my tv? I have a 4 year old Samsung LCD (LNT4069FX/XAA.) A few months ago the image started ghosting, or flickering and repeating itself multiple times down the screen, accompanied by a slight discoloration and / or darkening. At first I could "fix" the problem by gently applying pressure around the frame, or by swiveling the TV on it's stand back and forth. Once the problem was "fixed" the picture was perfect, and would remain that way until the TV was turned off, where I would have to start all over again the next time it was turned on (usually at least a few hours if not over night in between.) Eventually the turning / applying pressure did nothing. The TV would however "fix" itself after approximately 10 minutes. Again, resulting in a perfect picture and lasting until the TV was turned off. Over the course of 2 or 3 weeks, it would take more time upon start up for the problem to fix itself, 15 minutes, 20 minutes, until eventually no amount of time would solve the problem. It is worth mentioning that this occurs on any inputs, and even with no inputs - it is definitely the TV, not a cable or a source problem. I happened upon a similar complaint on your site, where the advice given was to replace the LCD converter, which I did, and the problem is still apparent. Do you have any other solutions that I may try? I would much rather fix this TV instead of buying a new one. Thank you for your time! - Jim D (the article I mentioned is here...) http://www.fixya.com/support/t8380218-samsung_hdtv_ln_t5271f_approx_4_yrs
