Question about Philips Magnavox 27MS343S 27" TV
I purchased a new Magnavox LCD TV (Model# 19MF337B/27 in April of 2008 from BEST BUY, of Annapolis, MD. I was naturally hoping to have years of trouble free use from the TV as Magnavox has a fine reputation.
After approximately 1 year of trouble free service a problem with the TV developed. It has become extremely difficult to turn the unit on. It shuts itself off repeatedly and then turns back on for a few seconds This process can last up to 20 minutes each time the TV is turned on.
Now the sound won't come on, even when the picture remains on.
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
