Hp pl5060 Plasma TV has no sound or pix. Screen flashing white


I have a seven year Plasma TV HP PL5060. When I turn on the TV, I have sound but no picture, the screen display (power on) is a snowy blue screen and vertical pink stripe. What is causing this problem and how can I fix it cheap. I can afford a TV repair man at this time, because I am laid off from work. Thanks.

Hp pavilion dv7 notebook to bravia KDL32BX400 HDMI problem


The picture that is output to the TV screen form the notebook could be distorted because the notebook graphics is overheating or not powerful enough.

Since it works for some time and then changes I would say this is a typical notebook overheating problem.

Clean the intake and exhaust vents of the notebook, and ensure that air can flow through from the underside. Raise the notebook underside off the surface, it helps too.

Take care!

Samsung HP-R4272 tv has been working fine for the past 4 years. now the tv picture is blank but the power supply is ok and the audio is fine too.


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.

When TV is off and there is a power outage the TV


This TV has a Power Standby feature (pg. 40 of your manual) which allows you to more quickly turn ON the TV. When power is lost and then restored, your TV will display the HP logo screen while it boots the digital circuits. After it is finished, (unless it was previously turned on) it should appear to be OFF. This is normal operation. If you like, you can change this setting to LOW POWER. At this setting, each time you turn on the TV, you will see the HP Logo screen and picture/sound will appear after 20 seconds. Again, take a look at pg. 40 of your owners manual for more information.

Samsung HP-R5052 Plasma TV


It related with Power Board(50%) or Y-Main(50%).
But, if you use the power bar with surge protacton, need to check
the power bar's lamp when the TV is turning on & off.

Picture will not come on.


I found this in the user manual. From what you've said I would check the second paragraph first. I hope this works for you.

On your computer check; Power, Signal Cable.
The TV is using its power management system.
Move the computer’s mouse or press any key on the
keyboard.

On your equipment check (STB, DVD, etc) ; Power,
Signal Cable.
The TV is using its power management system.
Press the Source button on the panel or remote control.
Turn the TV off and on.
