I have a philips Dptv335 60pp9363h, power light on but no picure or sound,are the bulbs blown? what about sound? i dont know much about this,i bought for 50 dollars..

John,
You wrote that the power light is on. Is it blinking? A blinking light can be a service code that can be researched online and narrow down the issues.

TV has power but picure doesnt come on - flashes 'please wait'

Hi,

There are a number reasons why this might happen:
  • The backlight has gone (Find a dark place and shine a torch into the screen and see if you can see an image in the background, if you see an image then the backlight has gone) - Needs a new backlight (Engineer to remove and fit) or have a new panel fitted.
  • The panel has died - Need a new panel
  • A cable has worked itself loose or is broken
  • The inverter has gone - Need new inverter
  • The driver board is faulty
Thanks

Tv wont turn on

hello, usually if your panny is blinking it means theres trouble with your power supply but depending on the number of blinks cuased by a fualty or shorted internal board and this will cuase your tv to go into shutdown mode, it depends on your model number and year it was made.
your best bet is to have a qualified service tech give you a estimate for the repair needed. as long as your screen is okay it will be easy for the service tech to locate and fix your trouble

panasonic blinking codes can pin point the troubled internal part, these blinking fualts are cuase by internal boards with malfunctioning circuts info below for 10th gen 2007 2008 plasma model service

12 Blinks SOS:
On the A board, transistor Q2301 monitors the Sound 15V line and the operation of the audio power amplifier IC2301. If the audio output circuit, IC2301, or the 15V lines develops a short to ground, transistor Q2301 goes into conduction and applies a high to pin 118 of the MPU, IC1100, triggering a SOS condition. The power LED blinks 12 times.
12 Blinks SOS: We have also discovered that 12 blinks of the power LED may also be caused by a defective SS board. To determine the source of the shutdown, disconnect the connector D5 and connect the unit to the AC source. If the panel turns on and the LEDs of the SS and SC boards stay on, the problem is on the A board. If the panel does not stay on, the problem is likely to be the SS board.

hope this helps

Color fades out on tv

I have the same tv and the same problem (color banding, incorrect colors, colors blinking) occured after I replaced the lamp. I had a tv repairman take a look at my unit and he said the color index was incorrect, the tv doesn't know the correct colors to display. The best way to fix that problem is to replace the "light engine". The repairman replaced the "light engine" to my tv and everything is working great. My tv was still until warrenty so I don't know how much a new "light engine" would have cost.
