    On the right side of the panel, under the little flap, do you get any lights flashing or solid? If so which lights, what color, and how many flashes? (for example 3 flashes every 5 seconds)

Intermittent loss of picture is most often brought on by an intermittent lamp or ballast board. When you lose the image, look at the rear of the TV for light coming through the ventilation vents. If you don't see any light, its likely the lamp or ballast. If your lamp has more the 3000 hours on it, replace it regardless of whether its the only defective component. It will fail just when something good is on TV!

My tv have a very typical problem it goes to blank screen but the power is on after few seconds it came back as usual ok. this problem comes down after running more than half an hour constantly.

First make sure you have the latest firmware for your tv by going to Panasonic website. Go to the support part of the site an look for any update in firmware.
Once you have the latest firmware and if the problem persist, try to look for any source of heat close to your tv and eliminate it.
If none of the above works, contact your retailer for a repair, this looks like a overheating problem.

That seems it might be an issue with your ballast. With time this could cause the picture to go away, discountdashmerchantdotcom

The problem is with the EEPROM in the TV that needs to be reprogrammed. But you need to have the proper Correction Tool (LSUQ0100).
I don't think it's available to the public. Call a Service Company, but make sure they have the “Correction Tool”.

Thanks for using FIXYA, big IRISH.

Lamp indicator flashes red 3 times every 5 secs.

Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.

PT-44LCX65 Convergence

Look in the service manual for the section on using the adjustment set-screws. (I'm not an expert, but this sounds like what you are looking for.) This section is somewhat toward the back of the manual before the electrical schematics and part explosion pages.
