Question about Dynex "- 46"" Class - LCD - 1080p - 60Hz - HDTV DX-46L150A11"

Open Question

I have a 46" Dynex LCD TV that comes on, then after about 5 min - 3 hours it will turn blue or white and blue and make a really loud on going screech (That scares the hell out of me).

I have a 46" Dynex LCD TV that comes on, then after about 5 min - 3 hours it will turn blue or white and blue and make a really loud on going screech no matter the volume. The remote will not work and I have to unplug it. I can then plug it back in and the same things goes on. While moving the connectors around slightly I notice some popping sounds while the TV is on, even if it's not an audio cable I'm touching. Anyone have this issue. It's less than 3 years old.

SOURCE: Dynex remote sticks on channels and does not always lower volume

I think you'll find that the tv is at fault. I, unfortunately bought one of these **** things as well. If you try to turn the channel, or volume, at the tv itself, you'll find that it won't work either. Seems to happen when switching between HD and regular programming a lot, but can happen at any time. You get what you ( and I ) paid for....

SOURCE: New 40 in Dynex having issue

Just got off the phone with Dynex, sounds like a common problem with a recent batch.

Tech support suggested returning the tv to futureshop/bestbuy since I'm within 30 days of purchasing.

SOURCE: blinking light on 37" Dynex LCD

I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

Did you check the side of the television for the AV/Compsite ports (Yellow, Red, White)? A lot of models have these connections on the side of the TV. You did not list your model number so I cannot really check for you.

Dynex dx-32l151a11 the picture is black and white with the dvd player

With a Black and White picture it sounds like you're trying to connect the DVD Player's "Composite" connection to the TV's Component Connection.

Composite is a 3 wire system with Yellow for the video, and red and white for the audio. On your TV this connection is located on the side.

Component is a 5 wire system, with Blue, Green & Red for Video, and Red and White for audio. On your TV this connection type is located on the rear panel.

Check to make sure you are hooking the DVD player & the TV to the same input types.

My screen is all white when i turn the tv on. the sound is ok but not the screen. i unplugged it for like 10 mins, plugged it back in and its still white. whats going on the tv isnt even a yr old yet and...

That is the symptom of the LCD panel not getting the signal from the LCD controller board due to no power to the LCD controller or blown surfaced mounted fuse on the controller board, that is the first palce to look, it can also be that the connector came off the LCD controller board.

Image lost after 5 min turning on the tv, sound was ok.

I would suspect overheating of an electric component in the power supply of the lamp (backlight) of your lcd tv. bring it in for repairs.
