SOURCE: Panasonic 32" HDTV keeps turning off

Check or have a repair tech check connectors AP1 and AP2. Vibration rattles the power supply board (a crappy design, as the board is almost "floating") and causes the wires in the connectors to break, and may make intermittent contact. Heat may also cause intemittent contact. A very common flaw.

SOURCE: Panasonic 32 inch LCD TV will not turn on-red light flashing

The number of flashes is an error code. Count the number of flash. It looks like one of the boards in your set is failing intermittently. Panasonic codes for a guide as a starting point. Exact board STILL has to be verified;
One Blink: One blink of the power LED indicates a problem in the inverter circuit located on the LCD panel. The inverter board is not to be repaired in the field. Therefore a replacement is required.
Three Blinks: Three blinks of the power LED indicates an over-current or over-voltage condition in one of the DC supplies of the AP board. The AP board is repairable. Therefore the use of an ohmmeter and peak-hold-voltmeter is required to determine the cause of the shutdown. An over-voltage condition is definitely a defect of the AP board. An over-current condition may be due to a short circuit located in the AP board, A board, or the LCD panel.
Five, Seven, or Eight Blinks: The A board is responsible for five, seven or eight blinks of the power LED. The MAIN +3.3V, MAIN +5V, and MAIN +9V sources are all produced on the A board. The detection input pins of the MPU, IC1100, monitor for their presence.
Four or Six Blinks: The AP board is responsible for four or six blinks of the power LED. The DTV9V, and SUB_5V sources are produced on the AP board. The MPU IC1100 monitors for their presence when the unit is connected to AC Power. A short or open circuit on the A board may also be responsible for their absence.
Nine Blinks: Nine blinks of the power LED is due a short circuit in the audio output circuit (s) of the unit. The audio output circuit is located on the A board. Confirm the status of the speakers. If defective, perform a replacement. If ok, replace the A board.
Ten Blinks: Ten blinks of the power LED indicates a malfunction of IC4200, the frame converter. This IC resides on the A board. Therefore ten blinks of the power LED requires the replacement of the A board.

Your powerboard is damaged, and need to be replaced.

Sometimes it appear the TV is working again with no problem but it is only a matter of time for the board to get completely damaged.

SOURCE: My panasonic 42" plasma wont turn on, but the power light blinks

With this symptom, it is impossible to tell what the exact "Cause" of this symptom is. The LED's do not tell us what is wrong, sometimes it may indicate the "Area" in your case it is the X board. BUT thats NOT where the "Fault is" thats just the part that is affected. These days unlike the "Old" analogue days it just isn't realistically possible to fix anything but the most basic of problems with todays sophisticated units. This is quite apart from the Safety aspect, any unit that can cause a firs or have an explosion, or both, is NOT to be treated lightly, and and the repairer, of the unit is legally responsible, another thing to think about. Also, one must have tools, a Multimeter, a soldering iron, a deslodering iron, an oscilloscope, a signal tracer, tools, and most important of all, a Service Manual, without which, there is no way to even begin to understand and fix it, and more importantly Program it, AFTER it has been fixed. As these days a TV, is a PC, a Tuner, and an HDTV Monitor, and more, all in one. in the "old" days TV"s were more, rudimentary, and built to last for 20 years, and a "Parts" supply was set aside. They usually used to fail for only a few reasons, and they while still difficult, were less difficult to repair. Electrical knowledge was transferable, and they could be and would respond to, This-is-the-symptom-This-us-the-Fix, But that no longer applies, as now, it can be a Fault on I squared Bus, or "Sensor" failure, or it simple may have "Crashed" just like a PC, It could be a Diode go bad, and that will stop the whole thing. You see, in the day, the sets were Very "Fault Tolerant" because they were Analouge, and a faulty, component, or more sometimes, the set would always diplay something usually, and when they didn't it was one of anly a few things, sure there are always the horrid ones, and there are pleanty of those, but all in all it was quite easy. But with Digital Electronics, it either goes, or it doesnt, there are usualy few half measures. I mean thats the definition of logic either going or not. So it can take very little to completely paralyse a set, and generally give the only sysmptom, it can, by not working, usually No picture, or the like. So you, see the list is endless almost for any given SYMPTOM, as that is what is being seen, not the cause, as I keep going on about. Also any fault, usually involves the Power Supply, it is either the cause, the cause of the damage, or it is damaged. or ALL of them. Then after you have done the electronic repairs, you then must program the set to work, and align, and set up in general, any one of those settings missed or done wrong, back to square one. So, it is nearly always my professional opinion that one should always get a "Quote" form the manufacturers recommended service center, I cannot stress how important that last point is. It is even worth the cost of shipping. you see an authorised service agent, will have trained staff, trained on their brand, also they have first hand access to parts, original parts. This will actually save you money and ensure you can actually get it back fixed. Of course asking for a "Quote" also gives on the option of repair or replace. Often my clients,do not go through with repair, unless it is moderate, but in some of the more costly jobs they see it, as do i, that a replacement, with a warranty, is a better option. As an aside here, one could then tear the TV down, and sell the Known Good bits. You'd be surprised who needs parts, i myself often must by from third party sources to effect a repair. So money could be recouped, somewhat,and help out someone else.

I have a panasonic tv that wont start up after a power outage, the tv was not on at the time. I have unplugged it for a hour with no results.


Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

My Panasonic tc-p50x5 plasma tv will not come on after a power outage. Dose It need a new power supply?


Wait a few days and see. There are some panny's that will not work for a few days when you have a power interruption, and it takes a while for them to come back on. If nada, then check the PS for voltages.

My panasonic tc-p50x5 will not come on after power outage. whats wrong?


Being in the field of electronics I can not stress this enough....POWER SURGE PROTECTION...and I am not talking about a power strip with "surge protection"...they are useless. That being said you had a surge that most likely blew out your main power board. There is a fuse on that board and if you are lucky that popped and it is an easy fix. If not, you will have to remove the board, get the numbers on it and search out a replacement. There are plenty of places online to get them but I use Allied Electronics. One thing to check while you have the tv apart is to check all boards for visible burn marks or damage from the surge.

Panasonic tv hdmi inputs not working


It appears that during the storm there may have been an electrical surge that damaged the electronics of your tv. If the tuner is working fine then the affected area (board) is the one that has the HDMI input sources.

My TV Won't Turn On


When you are convinced the mains cable is good, and in a socket with power, then you should try to switch it of an on with the power on switch on the TV. Not with the remote control. If that does not change anything I'm afraid there is something wrong. Cold be a fuse, but all other parts, like in the power supply or in all other circuit boards, could have a failure. It takes skill, measurement tools and time to diagnose what exact. It can't be done over the internet.

I have a 50" panasonic plasma tv. Model# TC-P50x5. I had unplugged it and went to plug it back in and the tv will not come back on. There is no red light on the tv or remote. Can someone help me please.


power supply module is known to go bad on flat TV's, if you change it make sure you buy the upgraded model, because same model could go bad soon again. but I would check power to wall outlet as first option. and power cord as second.

Won't come on after power outage


hi is it totally dead if so it's possible the fuse inside could have blown, this will be on the power board, glass type, if it has and you replace it and blows again then there's a dead short on the power board or on main board hope it helps

Panasonic tcp50x5 will not come on


Try disconnecting all HDMI cables and plugging the TV into a new wall outlet. If the issue is resolved, it may have been caused by a small power surge from either your wall outlet or one of your source devices
