Problems with a Panasonic PT-51DX80

I just changed the lamp bulb. Why do I get a blue screen on the I just changed the lamp bulb. Why do I see a blue screen on my Panasonic PT-43lc14. See photo. attached.

If model number is correct here PT-51DX80 the set is blanking (turning the 3 tubes off for a variety of reasons)

Take a peek inside with set on(carefully) to see if the three lens display light and a picture (red, green and blue).

THAT IS GOING TO MOST LIKELY BE A PROBLEM WITH THE OPTICAL ENGINE AND PANASONIC HAD SEVERAL MODELS THAT HAD PROBLEMS WITH EEPROM CORRUPTION THERE WAS A RECALL TYPE OF EXTENDED WARRANTY I SUGGEST CALLING PANASONIC THEY WILL SEND SOMEONE OUT TO FIX IT MOST LIKELY FREE OF CHARGE :)

These sets have several common problems which are listed below.

Problem #1) Convergence

Yours may have one or more of the following symptoms

• Screen Looks 3-D
• Colors wont align
• Screen may look distorted or warped
• No Audio/Video - makes a chirping sound.

Problem #2

Another common problem is dull or washed out video.
Your TV may have one or more of the following symptoms....

• Dull looking picture
• White looking picture
• Halos around objects
• Red/Orange looking picture

You can see some more examples and find the fix here...

Had same problem with Red. Could not adjust. Funny broken lines. Found this link:

Replaced the ICs. Was disappointed at first 'cause it was still all bowed out, but then realized that the Convergence 2 "target" can be changed with the number keys. Working thru 1-9 and going back to readjust as necessary adjusted each one into perfect alignment.

Problem solved. TV works great.

I should add that while I am reasonable technically adept, I am a software geek and never soldered before... hardest part was getting up the courage to dive in and do it myself. Glad I did.

Sounds like you have some leaky resistors or you got a bad IC.
But did you go in to service mode to line things up start there first then follow the other paths.

Can you post a picture of what your screen looks like and I will try an assist you with the problem.

Hi Kracka,

Are you able to post a picture of the problem?

It sounds from your description that it might be a 'convergence' problem which is when the red, green and blue parts of the image aren't alligned properly.

Check in your menu to see if there is a convergence setting.

Hope this helps

Just have Panasonic tech do "eprom upgrade".

The PT-53WX54 is a standard projection set and does not have a bulb. It has 3 separate picture tubes. If you have lost the picture completely, not even on-screen menu, then something has stopped working in your set. It could be a video processor, vertical deflection or possibly a convergence problem. The set should be serviced by a qualified tech familiar with the Panasonic projection sets.
