Insignia TV picture cuts out after 3-4 minutes

by tbonfig / February 23, 2010 3:47 AM PST

So I have an Insignia (Best Buy's brand) 32" LCD TV that stopped working last week. I've had the TV for 2 years with no trouble at all however the other night the picture cut out (I use an HDMI cable hooked up to my HD Cable Box [Cablevision]) and an "Unknown Input Timing" error message popped up.

I've been on and off the phone with Insignia trying to get them to repair this thing even though its out of warranty (apparently when I purchased the TV it only had a 1 year warranty however all of the more recent TVs within that timespan now have 2 year warranties, under which my TV would've been covered, go figure). They claim they can't do anything blah blah blah.

I don't feel like spending $150 for someone to come out and check the TV or repair it because if I'm going to spend & gt;$50 I would rather just purchase a new television. Unfortunately I'm getting married in June and don't have the surplus to purchase a new TV.

Anyway, I'm at the point now where I'm contemplating opening the TV up and seeing whats back there and if its something I can take care of myself. I'm not electrician or electronics expert however I've messed around with my laptop tons of times and fixed little things here and there on it with the aid of instructions on the internet.

I plan on doing some research later this week, however I figured I'd reach out on CNET to see if anyone here has any experience opening up TVs and repairing them?

As of right now, I've troubleshooted the problem and this is what I know:

- The TV will turn on and work perfectly for about 3-5 minutes before the video/audio cuts out when hooked up with the HDMI cable.
- When hooked up via component cables, same thing happens within 3-5 minutes however the audio will remain on and the video just cuts out.

Yes I have tried different HDMI cables and different ports on the TV. I also tried hooking up a different input device like my laptop but that still has the same problem

TIA to anyone that can provide some suggestions or help!

I am getting the same error message on my insignia LCD TV. It was working fine before i plugged my PS3 in to my new computer monitor with HDMI capabilities. I then tried to plug my ps3 back into the Insignia and now that error message pops up from time to time. Other than that i just says NO SIGNAL.

Is happening widely on the slim PS3. Try resetting the PS3 resolution. Hold which button?
