Sanyo DP42849 in particular is known to fail into a mode where it would not want to power on and this would have nothing to do with the power board and bad capacitors.

Please note that this does automatically mean the problem is NOT in capacitors or that the problem you have is the same that they are known to develop.

If anything, most Sanyo models are also known to come in several , often completely different sub-models (they call them chasis), so for example Sanyo DP42849 chasis P42849-03 is completely different from chasis P42849-04.

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.

  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

    Didn't you read the top rated solution? You should have. The problem is not in the power board at all...you can change it all day round and it still won't make a difference.

Hi there !

The best solution is to run restore system back to earlier when it works before. Just go to start menu, choose accessories, choose system tools, choose system restore and choose the earlier date that works fine before.

I got a Samsung Gravity and it wont turn on.


dear,

if your phone dropped in water then the first step to be done is immigately remove the battery and then let it dried through a table lamp. you should keep it under 100 W test lamp at a distance of 5-6 feet. if it worked fine after dropping in water and again shut off then open the cover and do this method..

goodluck....

You can try to restore your system to an earlier point, maybe you changed somenthing into your settings accidentally or a new software installation moved something.
CLICK ON START
ALL PROGRAMS
ACCESSORIES
SYSTEM TOOLS
SYSTEM RESTORE
choose restore my computer to an earlier time
NEXT
choose the closest system checkpoint since it worked fine click next
your system will be restared.
If it does not work you can try to an earlier point.
