Question about Dynex DX-LCD37 TV

1 Answer

Blinking light on 37" Dynex LCD

Our t.v. won't even turn on. It was working fine the day before. Then 30 minutes into our cable watching. The screen flickered and shut off. We turned it back on and 5 mintues later it flickered, but this time a white cloud came across the screen. We unplugged the t.v for 2 hours and now the t v wont turn back on. Sometimes it gets close to turning on, but we just get the white cloud before it shuts off. Everytime we try to turn it on the green power light flickers then shuts itself off.

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.
Solutions?
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

Bad power supply,Hard to find,They went out of business. may try to find a remanufact,or used from Shop jimmy,or even Ebay. Encompass does not have them. This is why I recomend Extended warenty. I handel all of central FL.Best buy was giving a trade in for another brand TV. If you get rude enough,They might let you return it. Trust me is works often.

There is no picture, just sound.


I have a 32" Emerson that did the same time.
The problem with mine was one of the Power Inverter Transformer when out. It used 6 of them to power the LCD screen.
I believe yours will have more than 6 since it's a bigger screen.

The Power Inverter Board is all one piece, the best place to get one at a good price is Shopjimmy.com

My 2 month old 37" LG HDTV won't turn on...


You might consider using Best Buy's "Geek Squad" just to make sure the set is not a dud.   I'm sure if it's near to the 30 days, they would be real schmucks not to replace it.   But, maybe it's just a setting somewhere in a menu.  Have a good look at the manual with a beer, and I'm sure you will find something useful.
Good luck.

I just got a 42" komodo by Sceptre, same problem, except "SCEPTRE" showed on the screen. I was sent a USB key program to insert in the service slot in the back and it reflashes the bios. This is old news for you but maybe new for someone?
