Question about Panasonic PT-51HX41 51" Rear Projection Television

Panasonic PT-51HX41E TV Turns off within 3 seconds!

I am a newb at tv repair and I also don't know much about the elictrical lingo being used on this site, but I saw some similar problems on this forum but couldn't figure out how to apply the solutions because i couldn't understand what was being said.
Here's the problem: The tv quit working on me one day and everytime I turn the tv on it turns back off within three seconds. The only way it will come back on again is if I unplug the tv and plug it in again. I had the tv looked at by a professional and he couldn't tell me anything except that I needed to replace the whole motherboard which would cost $700. I haven't taken the back off the tv yet because I'm not sure what I would be looking for. Can you guys give me any suggestions and tell me what steps I should go about first.
Thanks alot!

First of all. The set is going into shutdown mode usually due to a component not functioning which allows a regulated voltage to rise and the set will shutdown to prevent further damage. Most repair shops have gotten away from component level repair as its easier to just replace the affected board. However this is probably something you can repair yourself if you have some experience with checking voltages with a digital meter and have some soldering abilities. However I would recomend not even attempting without the service manual and the understanding that there are dangerous voltages that can be present even when the set has been unplugged for a long time. If you would like the service manual I can post a link to the site that has the service manual and they will provide the free support that willhelp you diagnose the set. Its a free service they offer all you need to do is purchase the manual so you will have the info in front of you and they will exoplain how to go about checking and diagnosing the set. let me know if youd like the link and I will post it. I am one of their support techs.

I have a panasonic PT-51HX41E 52" projection tv

A tech might be able to get into the hidden tech menu---sub brightness and sub contrast settings are there and it is not real easy to get into and does vary from model to model---access is with the original remote.

A suggestion if you can not or do not want to pay would be to search with Google and the model number for a "Service Manual" which will in it have instructions and indicate how, it will also have a list of items in that menu---be careful what you adjust there.

Look to see if sets power light blinks a sequence after it shuts off. The most common on this model is a series of either three OR five blinks.

Let me know what you find and I will assist you.

It turns itself off automatically.

There can be several causes for this, few of which you can do anything about. However, a few things to try:

1) Replace the batteries on your remote control.
2) Try resetting the logic functions on your tv by unplugging it for a minute, then plugging it back in.
3) Try covering up the infra-red receptor on the front of your TV to see if you're getting unwanted signals from the receptor. taping a piece of foil over that area is perfect. If it doesn't stop after doing these two things you'll probably need to take it to a shop.
4) If this does stop it, then look for unexpected signal sources. Have you added a remote control extender? Added a new device to your audio-video system? Changed to a new remote?

I hope this helps. Joe

Bad color then no power on 51'' panasonic cinemavision

Check the power light for blink code--usually if this model shuts down the power light will blink in a sequence--3 blinks a pause and 3 blinks is short protection--usually means a convergence circuit problem.

Panasonic pt-51hx41e tv screen codes

I found this on the net let me know if this works for you Once you are in service moce on a Panasonic you must continue through all steps to the end to exit. It starts with the B parameters, then C, S, and M, then you can exit by pressing power and action ON THR RECIEVER for 2 seconds. The TV will turn off and come back on on ch3 with sound. BTW, you advance thru the menus by pressing power on the remote.
