Tv keeps disconnecting from digital tv, returns within 5 seconds but highly annoying! pictue goes blank and sounds goes aswell , almost like the tv has turned off only to restart itself

Sounds like you are deleting the links, not the empty directories.

First thing to do is replace the cable with a new high quality one. They can go faulty. If that doesn't work, check that you are outputting the correct signals from your devices, plus it is set to pick them up. If that doesn't work you might have a fault possibly on the TV.

I have exactly the same fault and looking around so has lots of others aswell!

The power supply board is dead.Those high voltage transformers on the power supply board,one those power coil have a short in it,that why it cause this shutdown a have a loud electrical current noises.Tries websites like Shopjimmy.com.Ebay.com to buy a new refurbish power supply board for the replacement,should solved this loud electrical noises shutdown to tv.

Hey djames1971 - did you ever get this resolved? My Philips is doing the same exact thing now; sooooo annoying. If I keep monkeying with the exit setting it eventually goes to the TV and stays there, but it doesn't fix it by any means. Next time I go to turn it on I have the same battle with it.

If this is a flat panel LCD tv, this is a sure sign that the panel itself is bad. I have seen this before. Tv comes on works fine then within 5 minutes goes blank.

Sounds like its going to sllep too soon make sure you do not have it set in your video card settings. also try it on a diffrent computer. if that does not shore it up replace the acpi board

Hi , I have the same problem with my LT-42X688,so i called the service of my extended warranty provider . the TV technician just left and told me the motherboard is the problem. he said its the third one this week he has seen with the same symptoms. he ordered the motherboard and i've got to wait 5 to 7 work days before the part will be in . I will keep you posted when the guy will return.

Good Day, checho3435;

Look for fluid on the PCB's or check these items:

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source). Good Luck, big IRISH>

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
