The green output section [green video output] section to your TV should be checked. Even a loose solder terminal at this board can cause this fault. The video output card can be seen plugged onto the neck of the projection tube.
Well you need to adjust the convergence board manually, if after this the picture still has this problem then the convergence board itself is faulty and most likely has to be replaced.
please follow the below link to know how to adjust the convergence board -
and please follow the below steps to replace the convergence board -
1. Unplug the TV from the power supply. Remove all cables and wires from the rear of the TV. Remove the fiberboard cover from the back of the TV.
2. Before disconnecting any wires on the circuit board, attach a numbered label to each wire. Take a digital photo of the circuit board as you number and disconnect wires. Use a Philips head screwdriver to remove the main circuit boards from the frame that supports them.
3. Search the internet for "STK392-110" and purchase two replacement convergence chips. (This assumes you have verified STK392-110 is the correct Convergence chip. Notice the photo shows the chip circled and the chip number is clearly seen.)
4. If you do not feel comfortable soldering electronics you will have to pay to have the new chips soldered onto the main circuit board. If you can handle this step, make sure you use thermal compound (heat sink grease) when attaching the new chips to the aluminum heat sink.
5. After replacing the faulty convergence chips, re-fit the circuit board back into the TV frame and re-attach the wires. Use the digital photos and numbered labels to make the correct connections. When all the labeled wires have been connected to the circuit board, remove the labels.
6. Replace the fiberboard cover on the back of the TV. Connect the power supply and cables.
7. Turn on the TV and check the picture. The picture should be drastically improved. If the picture is slightly blurred, use the on-screen menu to adjust the convergence.
This sounds like a line timebase failure. The line timebase works at about 15 thousand cycles per second (15KHz) which may be audible to some people due to the iron-ferrite materials used (magnetostrictive).
The line output transformer is highly stressed and also has the rectifier diodes in the outside if the windings. It is all very well insulated to guard against moisture and dust but if it breaks down due to the high voltages (25Kv) the arc produced makes this squealing noise, and of course it burns out, and breaks down. This may not blow the fuse if there is not a short circuit. So get an engineer if you are not sure about changing the line output transformer.
to determine it is a tube cover one at a time when the reddish dots are there. if they dissappear when one of the tubes is covered it is the tube but other wise U have a bad chip
Check the Input Source: Make sure you have selected the correct input source on your TV for the device you are using. Use the remote control to cycle through the input options until you find the one connected to your video source.
Check Video Connections: Ensure that all video cables (such as HDMI, component, or composite cables) are securely connected between your TV and the device you are trying to watch content from. A loose or faulty cable connection could result in a loss of video signal.
Restart the TV and Video Source: Try restarting both your TV and the device you are trying to watch content from. Power off both devices, wait a few moments, and then power them back on. This can sometimes resolve temporary glitches or issues with the video signal.
Check for Software Updates: Make sure your TV's firmware is up-to-date. Sometimes software updates can resolve compatibility issues or bugs that may be affecting video playback. Check the settings menu on your TV for an option to update the firmware, or visit the manufacturer's website for instructions on how to do so.
Reset Video Settings: If you've made any changes to your TV's video settings, such as resolution or picture mode, try resetting them to their default values. This can sometimes resolve issues with video playback.
Try a Different Device: If possible, try connecting a different device (such as a DVD player or gaming console) to your TV to see if the issue persists. This can help determine whether the problem lies with the TV itself or with the original device you were using.
Contact Panasonic Support: If none of the above steps resolve the issue, it's possible there may be a hardware problem with your TV. In this case, you may need to contact Panasonic customer support for further assistance or to schedule a repair.
Check the Power Cord: Ensure that the power cord is securely plugged into both the TV and the power outlet. Make sure there are no visible signs of damage to the power cord or the plug.
Inspect the Power Outlet: Try plugging another electronic device (such as a lamp or a phone charger) into the same outlet to verify if it is functioning properly. If other devices work fine, then the issue is likely not with the power outlet.
Check for Tripped Circuit Breakers: Check your circuit breaker or fuse box to see if a circuit breaker has been tripped or a fuse blown. If so, reset the circuit breaker or replace the fuse and try plugging in your TV again.
Test with Different Power Source: If possible, try plugging your TV into a different power source altogether, such as a different room or building. This will help determine if the issue is specific to the power source you were previously using.
Contact Panasonic Support: If none of the above steps resolve the issue and your TV still does not power on, it's likely that there is a hardware problem with the TV itself. In this case, you may need to contact Panasonic customer support for further assistance or to arrange for repairs. Be sure to provide them with details of the troubleshooting steps you've already taken.

The VCR and DVD recorder won't eject/open on command either, so my guess is the capacitors on the power board are dead. Upvote
