Pin 91 of the MPU IC9003 monitors the status of the SS board. During normal operation, pin 8 of connector SS23 outputs a low to pin 91. If the SS board becomes defective, a high is provided to pin 91. As a result, the unit shuts down and the power LED blinks 8 times.

Hi and welcome to FixYa,

Initially, the shutting down indicates that the built-in diagnostics has sensed a fault and gone into protective mode. Additionally, the blinking power LED indicate an error code that would point to the general area needing attention. 8 blinks points to Driver SOS 3 SS Board (SS energy recovery circuit). Unfortunately, this fault is hardware related and could not be fixed with button pushings, reset or unplug from the mains.

Th

Good luck and Thank you for using FixYa. Happy Holidays.

    This of course would mean opening the unit, perform voltage measurements, determine faulty component and subsequent part(s) replacement. Further, a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron would be required. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings.Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Replaced lamp on mitsubishi wd62527 worked for 10 minutes then shut down. Now red lamp light is on


If the red indicator light on the front of your HDTV is glowing a solid red, you should first unplug the AC cord from the wall power outlet and wait for 60 seconds before reapplying power to the HDTV.

After you turn the TV on, if it doesn't power up, try holding the power button down for at least 8 seconds. That's supposed to force a system reset. If your model has a system reset button, use that instead. Press the reset button for about 20 seconds...release it and press it again for 20 seconds, release it again and the led will blink just for a minute or two. You should now be able to turn the TV on.
If after several attempts, the HDTV has not fully powered on and the LED on the front of the HDTV is still glowing solid red, you may want to reseat the lamp.

If reseating the lamp has not resolved the issue then your next step is to order a replacement lamp.

The Power Light is Red


yeah, should stay red when unit is turned off, indicating there's power but it's doing nothing.

Per user manual:
Solid red - power off (standby mode)
blinking red - power off (now cooling)
blinking green - power on (preparing to light lamp)
solid green - power on

Plasma tv screen goes black once you turn it on. Only sound


I have a panasonic TH-42PX60U plasma TV. When I watch TV programing I have no problems, or with the DVD input. But if I switch to another input, be it video game (PS2) or vcr the screen sometimes goes black and the red power lcd light next to the power switch flashes. Holding the power button in for a few seconds will shut down the tv. Then I can turn it back on and it may operate normally again for a undetermined period of time, before the screen goes black again. This never happened when new. The tv is about 1 year old. Any ideas on this problem? Thanks Ernie

Well don't tamper with it just return it, there is serveral problem that may cause this, most likely it is the power supply board.
