After turn ON , blink 7 times and go off

I have changed all the HV capacitors in the PS , that look bad but remain the same problem, In this forum said that is a very knowm problem , but I didn't have any assistance from Panasonic, because I have bought the plasma in USA and brougth it to Venezuela, so Panasonic Venezuela said that dotn't respond for Panasonic products bougth in USA. And the Plasma Concierge service from Panasonic USA didn't give me any answer.
Please if you know which is the problem , tell me how to fix the problem
Thanks

I have a 42PFP5332 which doesn't turn on. When plugging in the power the green led on the power circuit board turn for a few seconds and then blinks for 9 times. After that it blinks for 10 times


Good day!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

I have a Panasonic Viera 42" plasma TV and the unit will not turn on. I unplugged it and plugged it back in and it blinks 7 times; the blinking stops for a couple of seconds and then it starts...


Hi
A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps in solving the problem...

KDL-40XBR4 bought 1/08. Turns on for 30 seconds with screen staying dark. Then it goes off automatically with the stand-by light blinking 5 times repeatedly. Took it to the shop and he said the LCD panel...


KDL- Bravia blink codes (Australian):
2 times-Main power supply voltage error (12V, etc)
3 times-Malfunction of 3.3V line
4 times-Malfunction of 5V line
(Voltage Supply to FE, etc)
5 times-Malfunction of power supply for screen
6 times-Malfunction of inverter or overcurrent, etc
7 times-Abnormal temperature inside unit
8 times-Audio circuit error (amplifier, etc.)
9 times-Fan malfunction
10 times- Digital FE circuit error
11 times-Malfunction of Trident IC or around IC
12 times-BH board error
13 times -Malfunction of balancer
If this is correct the 5 blinks is the power supply having problems, I would much rather change the PS than replace the screen. Also if screen is determine bad, look for class action lawsuit on Sony for defective screen, i am told they know all about this.

Sony kv-40xbr800 won't turn on, blinks 6 or 7 times


More than likely the D board is bad, one or mor of the capacitors is probably the culprit on the D board. This board is hard to find for most sets and Sony will probably give you the runaround. If you know of a good shop to take it to they can rework the board and fix your problem

Had the same problem with 2 bad capacitors,philips 42pf9631d 42


Well, if you have the same value and equal or higher voltage rating and installed with correct polarity then I would say you have other problems. I would need more input, such as what voltages have you checked for? What was the original issue?

Philips 42pf9630/37a, Blink red LED 7 times, No Picture No Sound


7 blinks indicates a bad buffer board, usually I replaced the Y board and the buffer/s about $500-600 in parts. but before you buy anything open the set and look at the power supply if you see two capacitors that look swollen , bulging on top they need to be changed and may solve the issue. the power supply is middle top . If you are not wanting to repair it yourself then know that you do have some circuit board repairs needed.
thanks

7 red blinks


Is the light blinking 7 times on front of TV ? If u take the back cover of the TV off you should see two leds on the bottom right of power supply turn on when u push the power button. When the TV go into error protection on the upper left of power supply you should see. A blinking green light. Please inform me of the error it flashes and ill will be able to help further. ( Serveral possiblilties it could be from audio, bad power,and faulty Y-main.)
