SOURCE: WD-52628 Mitsubishi - change inputs

We had the same problem. Luckily, we had a service contract, so it was serviced yesterday. The fix involved the service guy going through a "service menu" and resetting the TV that way. He was not "allowed" to tell me how I can access the service menu, however. I do plan to research this on the internet in case it happens in the future. It is basically a software/computer problem, and unplugging the TV isn't enough to clear it unless the TV is unplugged for "a long time." The technician said the length of time depends on the condition of your capacitors. Anyway, as a temporary fix, he showed me that you can go into the PIP mode. The device toggle for PIP apparently did still work with mine, so I was able to switch the device on the secondary picture and then switch it to primary, then toggle the PIP off. Good luck!

SOURCE: panasonic plasma th-42px25 turns itself

The condition of your TV called power supply overcurrent shutdown. The TV is going into a protection mode to prevent further circuit damage. That's why it will not turn on or not powering up. I would concentrate on the power supply section board. Bad regulation of the incoming voltage could caused this issue although,there is a capacitor across the incoming line and nuetral.Maybe its leak or dry up and cause the problems,change it out with one of identical rating .I would probably also check the flyback circuit and flyback transformer although now you are getting into dangerous area,especially if you have no electronic experience background. It could be also be a loose ,crack or cold solder joint,a blown fuse,fusible links or other component .It could be one of several boards.Unfortunately the level of sophistication on these TV make it virtually impossible to diagnose them further without taking them apart and probing around with a multimeter and other tools.This TV is handy enough to take to a repair shop find a good one.You will probably have to pay $75 to $100....

Hope this may help you..

Panasonic TH-42PX60U 42"Plasma TV has left side of screen with no picture with large black and white vertical lines. Purchased in 2006, can it be fixed and how much?


Try disconnecting all of your source devices from the TV and see if the line still appears. If the line disappears, the issue may be caused by your source device or your cables.

How to setup picture in picture function on my tv. panasonic viera 42-px600u


This is controlled by the Split and Swap buttons on the remote; the size of the second picture can be adjusted with the Aspect button. First press split and use the Input button to select the source of the right picture of the split screen (TV channel or video inputs). Then press Swap and use the input button to select the source of the second screen. Swap again if desired or press Aspect to change the size of the main screen window. However, it is not available if you are using the HDMI, PC and SD Card viewing mode. Since the TV doesn't have dual digital tuners, you can't watch two different digital channels on the split screen.

The manual for the Panasonic TH-42PX600U is available from from Panasonic here: http://www2.panasonic.com/consumer-electronics/support/Televisions/Plasma-HDTVs/model.TH-42PX600U . See page 18 of the manual, page 10 of the PDF.

I hope this helps.

My picture scatters every minute or so and then comes right back....


The good: Deep blacks; decent video processing; accurate color that doesn't overaccentuate red; generous connectivity with two HDMI inputs; aspect-ratio control with HD sources.
The bad: Depth of black fluctuates depending on how much bright content is in a given scene; no PC input or picture-in-picture.
The bottom line: The Panasonic TH-42PX60U sets the standard for value among full-featured 42-inch plasmas.

Sound, No picture


Try another video source. Try a digital source and an analog source. If you still get nothing, think about replacing the DG board and the H board.
