Pioneer pdp-5070pu HDMI port 5 has a megenta hue to it. All other HDMI ports and component ports are fine. What board might need to be replaced?

I am certainly no expert about such things but a friend had a similar problem until he discovered he needed to get into the menus and switch on the port he needed to use.

Check
Apple - Apple TV - Connect Your TV

port or plug failure / damage

Do you have a second signal from your cable box going into the TV by a different port?
You can only use one or the other, not both.

with hdmi plugged in take power cable out of apple tv ,put power plug back in then look to see if you have a signal....

Check this link for details.

Do a factory reset to this set and proceed. Refer its user manual for details.

Hi.

To start ensure that each time you connect or disconnect the HDMI ports both TV and connected device are off.

Also ensure that HDMI input is active, as detailed here.

HDMI connectors carry voltage, and connecting the HDMI cable while TV or device is on may easily damage the HDMI port, making it unusable.

The HDMI 3 and Component 3 are separate input. The component input may work, and HDMI port may still be defective.

To test the port do the following:

Disconnect TV power cord, and connected device (eg. Receiver, DVD etc.).
Leave units disconnected for five minutes.

While power is disconnected, test connecting on port three a device that was previously working on HDMI 1. Also use a cable that you know is working.

Connect back power with HDMI cable already connected. If HDMI 3 is still not detected, then the port is defective.

In that case ring Pioneer at the number listed on the owners manual.This model is often advertised as only two HDMI inputs. Call Pioneer to ensure the third port can be enabled.

HI, the best way to do this is to disassemble the set and post all the individual internal parts like the power board and main PCB logic and v boards, on line on a e-bay type of sale forum. this way, you can make more money. if you post the entire plasma screen with the crack as is, you will not get many hits. is will be assumed that it is damage goods.

Breaking this set down and, posting the internal circuitry piece by piece will make you more money in this case. The power supply board will sale for at least 289.00. and the main logic(PCB) will sale for 300 to 350. i would go this route to maximizes your gain.

Greetings 4mother,

It would really depend on what type of hook up you are using. Most of the time a plasma television would be hooked up with either and HDMI or component cables. Your local store should be able to make a solid recommendation based on the items hooked up to your television such as cable or satellite box, dvd player, etc.

I hope this helps.

Thank you,
