32 inch LCD TV series 5 (550). I have sound but no picture

by colehen2 / October 14, 2009 9:03 AM PDT

I have a 32 inch series 5 LCD that is less than a year old. Today when I turned it on I got sound but no picture. I've double checked all the connections and everything seems fine. I even tried playing a DVD and went to the AV source (blind, by memory) and still no picture. I am a direct TV customer but don't see how that would be a factor. Any ideas?

If several inputs aren't showing any picture at all, call 800-SAMSUNG and set up a service inspection. Since you're under warranty, it's probably best to have a qualified tech take a look.

warranty is expired

Unfortunately just found out that, although the T.V. was a gift and although I didn't actually take the set out of the box until the end of October '08, it was purchased in September by the giver so I'm out of luck. I was told it could be the T-Con board....any estimates as to how much a new one (plus labor) could run me?

Sadly, this is a common problem with the 550 series. I had my main board replaced after 5 - 6 months and now it looks like it may be coming back again. I think Samsung should treat this less like an individual warranty problem and more like an across the board defect.

We bought this set for my 91 year old mother who died shortly afterwards. Her previous big console TV had lasted 40+ years. This set got minimal use after her death and now 1 year and 5 months after its purchase we have no picture! Took to a repair shop ($85 to look at it) only to find that the lamp or whatever that burnt out would cost $475 to replace (on a set that cost $650 originally). Am currently negotiating my way through the jumble of Samsung complaints departments but will scream from the rafters to anyone who will listen to me not to buy Samsung products as they don't stand behind their product even when it's a lemon!!

TCON Lockup
by SmartDigital / May 26, 2012 1:45 AM PDT

TCON boards are known for going bad, but this is more commonly linked to a TCON lockup, which happens between the cable provider box and the component it is plugged into, ie., TV or stereo receiver. You need to ensure that the cable box is configured for 1080i or 1080p, (whatever the component supports, NOT auto). Also, ensure that the cable box 4x3 override is configured for 480p, NOT 480i.

It's my bet that this is what you are experiencing. A quick way to verify this theory, is to plug an HDMI DVD or Blu-Ray player into one of the HDMI ports of the TV, direct. If it displays the movie direct from the DVD player, you are certainly experiencing a TCON lockup between the cable provider box and your TV.

Seems Samsung reps on here are not interested in keeping us up to date on this issue.
