There is a little card on the power board which blinks in sets of 6 flashes
there is no light on he scart board/input board
ive tried removing cables from y, x boards still the same
ive also changed the video scan driver board
still lashes the standby light
i put power to the tv i get clicks
i now turn on the power button the stanby light comes on,
then binks twice,
then blinks twice,
then goes out repeatedly
any more ideas thanks

Re: hi thanks for replying
The clicks you are referring to sound like High Voltage Leaks or Arcing. While it is clicking check for sparks around the high voltage transformer only with your eyes from a distance. If you see sparks shut it off immediately.

Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. 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 inverter board as card basis. http://electronicshelponline.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.
These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/ http://electro-medical.blogspot.com/
Blinking codes details of many popular brand TVs are given. Surf the site with patience.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.
The power supply is going out. It can be replaced fairly cheaply and is easy to do. You will need to remove back cover and look at serial number on power board sou can order same card. The power supply is the card the power cord plugs into.

Hi, The Standby/Power light of the TV blinks when there is any internal malfunction in the TV. The self-diagnostic function of the TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue. Few examples are given below; some of the issues may be resolved without the need for service. 1 blink / 2 blinks / 5 blinks: - This indicates that there may be a power-related problem with your set. 3 blinks: - This indicates that there may be a power-related problem with your set. The set will need to be serviced to allow a technician to determine the specific issue that needs to be repaired. If the power light flashes three times in sequence in a Lamp TV, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue. 4 blinks: - This indicates that there may be a back light or lamp power problem. 6 blinks: - This indicates that there is some kind of audio problem with your set. 7 blinks: - This indicates that there is a temperature problem with your set. Please check to make sure that the air vents on the sides and back of the set are not blocked or clogged and there is adequate ventilation around the television. We recommend that you check and clean the vents periodically to make sure the set receives adequate air flow. If the problem continues, the set will need to be serviced. 8 blinks: - This indicates that there may be a video-related problem with your set. If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset: Try the following steps to check if the issue can be resolved. Turn off the television. Unplug the television power cord from the electrical outlet. Let the television remain without power for 60 seconds. Plug the power cord back into the electrical outlet. If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television. If the issue continues to occur, service may be required. Thanks for using Fixya.
10 times blinking of your unit indicated that the processor sense the missing 15v from the power supply. This problem is quite technical since I've already read your post that you have a reading of 15v in P25.
Now, we have to examined it deeply to determine where the fault came from between the two board.
If you have a 15v coming from the power supply but its go to 0v after a while which trigger the 10 blinks, you have to check the feedback circuitry of the power supply for faults. If you can't find any faulty parts on that section means that the feedback circuitry trigger to shutdown because it sense fault in the D board.
Remember that it has a good regulation output from the power supply, the issue here is the feedback circuitry that sense the fault. If you are going to ask my opinion I've suspected that the fault is in the D board.
Hope I helped you.
Have a nice day!

Hi my name is Roety,
I can help you with your issue ,
6 Blinks is a bad Y buffer Board error code.
You can check for bad capacitors , but most likey will need the Y sus main, Y upper and Y lower buffers replaced .
Tech labot is about $250 plus parts about $600

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.
