Panasonic Viera tc-p65s2 - 7 blinks, won't turn on


I had the same problem with my Viera. if you disconnect the power and ribbon cable from the YSUS board (check youtube for how), the light led will blink 6 times, indicating the YSUS is bad. Check ebay for TNPA5175 board (about $115-160). The pop is one of the DG402RP chips burnout. These are about $4, but only available from China. If you can wait a month for delivery, you can solder the new one to replace the bad one. You may want to purchase several in case more are bad or it happens again.

We have a toshiba 72 dlp tv. We were in the living room in which tv is in we heard a pop. When we went to turn the tv on we heard sound but no picture and the yellow light on the front of the tv blinks 16...


Good day!!!


Your color wheel is clapped out. The part is not directly replaceable - they seal it in the light engine and won't sell spares. A rebuilt engine for this set will probably run you between 230 and 270 USD. Replacing it is a cinch if you can get another engine for it.

Popping sound and then the picture went out no sound makes a crackling sound and the blue led light just blinks


Hello

The sound you heard is probably a cap that has blown on the power supply. On plasma tv's some times you can hear the buffers pop but you said this is an LCD and that is USUALLY a blown cap.

The good news is power supply boards can be found on ebay. Or if you have a local electronics guy he can replace them. Sometimes a blown cap just happens, and sometimes its a sign of bigger problems so I tend to replace the board.

If you are comfortable you can take the back panel off, find the power supply board and look for caps with DOMED TOPS or BLOWN OFF TOPS. And then you can be sure. In most cases the power supply board is easy to find, the power cord plugs in to it.

PLEASE PLEASE dont put your fingers where they dont belong, and if you dont know what you are doing call someone who does. No tv is worth calling 911 to get your heart restarted.

Best wishes

I get no picture. the blue power light blinks four times. i took it in to get serviced. repairmen said it was power supply and complete y board. but i found out he wasn't very honest.


Sounds like a on/off sensor like I had with my vizio. the light would blink several times and finally the picture just went blank and it would not turn on. a similar thing happened to a friends tv also and both times it was a on/off sensor, in this area it costs about 30 or so dollars to fix. probably higher in the city

Panasonic TH 42PX50U Red power light flashes 6 times


Most of the time when this happens it is the ysus board, that noise you heard was a capacitor popping. Another board runs about $175 and thats if you do it your self. A shop will most likely charge around 500-600, hope this helps, you could also try contacting panasonic and trying to get past the tech and onto casemanagement where you might get somewhere with an out of warranty fix.
