SOURCE: panasonic 42-TH-42PV500B has flashinf light but no

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.

Hi Friends! I have a Panasonic TH-L32C20R. When


Something worth trying that worked for me and costs nothing is; remove all leads except the power lead. Hold the on/off button on the TV in until the light stops flashing, release button and and press again. If it fires up your good to go if not your nearly finished disconnecting everything ready to send off for repair! Good luck, BTW the number of flashes indicate a fault code that you can look up online.

HDMI STOPPED WORKING PANASONIC TH-42PV500B


I had a same issue with my Panasonic TH-42PV500B plasma television. I tried everything which is written above and can be found on different websites. Finally I decided to replace the HDMI Board itself. I was able to buy a used one on ebay, it was only 13 pounds with postage.It is relatively easy to remove this HDMI Board. You should just unplug the TV and remove all of the screws form the back which are fixing the back of the TV to the frame. There are plenty of screws. You should remove all of them! Remove the backplate of the TV. After this you can remove another metal plate from inside, which covers this HDMI board - 4 screws. After you can remove the HDMI Board - only one screw holding it to the main board. Replace the new one back and put back the cover plate and the back of the TV. And it is working. 10_19_2012_3_10_22_pm.png Panasonic 42 Plasma TV TH-42PV500B Part HDMI Board Order number: TNPA3626

My panasonic viera plasma screen tv will not stay on. Every time I press the power button, it stays on for 2 seconds then cuts off. Then a red light flashes 10times and then pauses.


Hello,

Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Take care in solving the problem....

My Panasonic TH-50PZ7OOU will not turn on. The red light on the lower left is on, but the screen is completely dark. pressing power button on both TV and Remote control gets no response.


Try to power it up with the remote control. When you hear the relay's click, see how many times the red light flashes. This will tell us what the fault is.

Need a four digit code for comcast universal remote for panasonic th-42px80u


Hello
Four digit universal remote codes for Panasonic TV are:
0171 0148 0054 0170 0062 0374 0381 0437 0950 0003 0070
Direct Code Entry
  1. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
  2. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks, then stays lit.
  3. Enter the 4 digit code from the code tables. Note: after a valid code entry, the red indicator turns off. For an invalid code, the red indicator flashes.
  4. With your device on, press CHANNEL UP. If the device responds, no further programming is required. Note: If some buttons do not operate your device, try one of the other codes for your brand.
Code Search If after trying "Direct Code Entry" your device does not respond, or if your brand is not listed, try doing a search of the code library for your code by following these steps.
  1. Manually turn on the device (TV, VCR, etc.) to be controlled.
  2. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
  3. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks once, then stays on.
  4. Press the CHANNEL UP button repeatedly (up to 300 times) until the device to be controlled changes channel. The red indicator blinks, then stays lit.
  5. Press and release MUTE to install the code. The indicator light goes off.
Most users will want to store VCR codes under the VCR button, Cable codes under CBL, etc. If you want to store a VCR code under CBL, etc., first follow the procedure for Direct Code Entry and press CBL in step 2 of Direct Code Entry, then enter ANY VCR code in step 3 of Direct Code Entry. Then follow the steps above for Code Search.

Just bought panasonic th-42x20k, when turn on hear a clicking sound and then turn off, red light under screen flashing 7 times


Red light flashing indicates that "SC voltage is floating". I'd recommend replacing the SC, SD and SU boards. Also know as the Y sustain (SC), Upper and lower buffer boards (SD, SU).
I suggest you contact your local Panasonic Service Agent as parts are only available from Panasonic and are quite expensive.
