Red power button flashes on and off, but no picture comes up.
Pin 93 of the MPU IC9003 monitors the status of the SC, SU, SD board. During normal operation, the photo-coupler PC6480 outputs a low to pin 93. If the SC, SU, or SD board becomes defective, a high is provided to pin 93. As a result, the unit shuts down and the power LED blinks 7 times.
I purchased a PZ77U and in November 07. I watched tv last night and worked fine. Turned it on this morning and it would not come on and the red power light is blinking 7 times. Called Panasonic and they will have a repair guy out on tuesday. UGH!!! Here is a link that explains the blinks if you get them.... http://www.avsforum.com/avs-vb/showpost.php?p=13057627&postcount=8421 Hopefully this gets fixed and doesn't happen again. Stupid electronics!!!!!
There is a guy over at circuitsquad dot com that fixes these boards. This guy is really good and he only charge $110.00 including free shipping both ways. You can call him at 347-831-6372
We have a Panasonic Hi Def TV Model #TH-42PZ77U. We have same problem w/blinking and not picture. Can't use DVD or VCR even as screen is black, but we have 10 blinks, not 7. Is there anything you can suggest? Husband has Alzheimers and I have cancer and we're old, so this is just what I need! It's no longer under warranty but has been very gently used. Would it be cheaper to order part and then ask someone to install or are there any hot buttons, so to speak, to say to Panasonic or Sears (where purchased) to get them to do it at a lower price since there seems to be slew of problems w/these boards.
I had the same problem. I called the 'authorized repair shop' and they came out, picked up the TV and fixed it. After it was fixed, it never happened again.
It's still one of the most awesome TV's on the market, so I'm cool with it.
Turns out there's a specific board that was built into it that needs to be replaced. Seems to me like they should do a recall on it to have that board repaired, but they didn't because it doesn't doesn't seem to happen to everybody.
Panasonic plasma concierge service guy switched board out saying it was the scan board
still took to shop
1 week later tv is back and working great
impressed with panasonic service
had for a few weeks now no problems
Bought TH42PZ77U panasonic 1st of nov.07 from sears.
Played 4 weeks. Turned on, no screen, red light flashes 7 times.over two weeks waiting for board to repair.
Played 2 months, same thing.Panasonic told tech. new board
also needed software up date. We'll see.
TXNSC1NZTU (SU CARD), TXNSD1NZTU (SD CARD) and TXNSS1NZTU (SS card) ordered on 24 Jan buy BestBuy tech. Hour after Super Super Bowl, automated message indicating unknown delay in delivery of the cards. (Ouch!) Has anyone else with this failure had luck (or not) with this repair?
Plasma finally repaired 5 weeks after failure. One large board with two large heat sinks running vertical was replaced. At first power up TV came up instantly. No adjustments or alignments necessary. BB techs great; BB service worst ever - WORST! Consider purchasing extended warantee through Panasonic vice a store like BB.

Ditto here. Bought the PZ77U 11/07
today, 2/9/08 blinking light 7 times no picture. Panasonic sending someone out in 3 days "he can/will fix it" is all I got, she seemed to recognize the "7 blinking light" problem....
You Guys need to contact a Professional, according to Panasonic Tech Support the problem resides on one of five boards. Its a scan voltage problem.

I am having the same problem as well the light flashes 7 times.
tonight - the same problem - rpower button's red light blinks 7x, pauses, then repeats. I've had the th-42pz77u for over three months. Tried unpluging the power cord to reset the set, but no joy. From other posts, this indicates a failed power supply.
Have the exact same problem on my replacement set. Have just over a month. Yes, red power button blinks 7 times.
Yep, same as these guys. Purchased TV in December 2007, installed on Dec 17 2007. Today, Jan 30, tried to turn on TV, nothing happens, but red lights blinks 7 times, pauses, and blinks 7 times. We've tried unpluggin the TV for a while, but no go.
BOUGHT THIS TV ONE WEEK BEFORE XMAS 07 AND TODAY THE SCREEN WENT BLACK WITH A POP SOUND. AND THE RED LIGHT BLINKS. JUST GREAT AS THE SUPER BOWL IS ONLY 13 HOURS AWAY. I DID BUY THE SEARS SERVICE PLAN, OR DO I HAVE TO CALL PANASONIC? I WILL HAVE TO WAIT UNTILL MONDAY TO CALL. AND NOW I HAVE NO TV , AND I JUST GOT AN HD BOX LAST WEEK.

Have the same problem.....sounds like it's going to turn on....then power light flashes 7 times. Unplugging doesn't help. Called Panasonic and they're sending someone in 6 days. Have had the TV less than 3 months.
Panasonic attempted to fix my set under the warranty, and the replacement card had the same problem. This is the third failure my set has experience with the exact same problem. Been weeks without set pending Panasonic warranty service. So the real solution even with Panasonic repairing is still in question.
same thing as everyone else. I have had my th-42pz77u since Dec 07. Watched tv just fine yesturday afternoon and last night it just wouldn't turn on. The light blinks 7 times then pauses and 7 more. Contoller doesn't do anything and very irratated that a $1300 tv breaks after 3 months and i have a RCA 32 inch tube that is 10 years old and works perfect

no power only flashing red light ...very expensive and I am very upset
Same problem here. The red light is blinking 7 times.
The tv is brand new (2 weeks)! .
Waithing for the tech.
same problem-red light flashes but no picture-is there a fix?
Same problem. 3 1/2 months old. Panasonic is not very helpful. I've already had a no show for repair appointment. Trying again tomorrow. The floor model at Sears was being repaired the day after I bought this when I went in to get a HDMI cable.
Mine just did the same thing. Did anyone have luck with the tv being fixed/
Panasonic Plasma 42 inch. 7 blinking lights. Called the Panasonic phone line. They set up a repair person to come within 2 days. He came and replaced several boards and it is fixed at no charge. I live San Deigo. Great job!!!!
same problen, no power or sound, 3 months old
red light flashes 7 times
called panasonic
waiting for service tech........
Same here. Flashing red light. Seven times. Not a happy bunny. Will call Panasonic in the morning. 9 months old.
The power is on but no sight or sound.I unplugged the tv from the outlet for 45 minutes the tried it. The power indicator flashes 7 tines the pauses then repeats the same sequence again and again.
GRRRRRR - same problem. Purchased in Dec 2007 - now June 2008 - TV won't turn on. Fan starts, dim flash then nothing but a blinking red light. Unplugging and replugging in does NOT help.
VERY annoyed.
same problem
was ok last night, can't turn on this morning. 7 months old
I will never by Panasonic again or shop at leons again unless I get much better servie this time than I did last.
Bought our TV dec 26 , 2008, this is our second time it has broken down, not impressed and told Panasonic and leons, if i don't get better service this time, this small community is going to hear about it, disgusted with both of them and as I said, no better service this time, they will be sorry about my advertising about both Leons and panasonic., Very frustrated.
blinking 7 times the power button
7 Blinking lights on TH-42PZ77U, won't turn on. Bought 2-1-08, used infrequently, should have used more so it would have broken earlier since it looks like this is a very common problem.
tv just went off one day, now when i try and turn it back on, the red light flashes and the screen doesn't turn on
need to install digital dg board on panasonic th-42pz77u
