Question about Philips 27PT81S 27" TV

1 Answer

TV LED Flashes then TV shuts itself off

TV shuts itself off. TV will be on for an undertermined time and Red LED power light on front will flash then TV turns off. TV will turn back on either by remote or power button on set and the majority of the time will continue to shut itself off immediately after being turned on. If TV is left off for a long time TV will stay on for about an hour then start shutting itself off again. I have a feeling that it is a chip problem and needs replacing. The TV has been a good workhorse and in all other respects a worthwhile purchase.

Re: TV LED Flashes then TV shuts itself off

Capacitor problems in power supply or a regulater isolate the power suppley by disconecting the line output stage/unplug scan coils for example and run a 60w bulb as a dummy load one wire to earth and the other to rail voltage colecter of line output transister if the bulb glows steady the power supplys fine

When you switch the TV on with the remote or on the TV. The TV comes on for a few seconds or minutes then switches itself off. The red light on the front of the TV flashes. Please HELP. Thanks Mary.

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.
Blinking codes details to many popular brand TVs are given. Surf the site with patience.
If blinks continue without any pause, the main board is faulty.

TV popped and shut off red light flashes 5 times then pauses

this specific type of TVs flash their standby light if the onboard testing system sniffed out a problem

so, as if your TV is trying to tell you "i have a problem and i need to be serviced"

i hope it goes well for you

TV does not turn on. Stand By LED blinks 4 times and pauses and blinks 4 times again Tv will not turn on...when plugged in the red stand by light flashes 4 can hear the tv turn on but a black...

On older Sony, sometimes a power surge causes the set to be in shut down mode. Try unplugging for 5 minutes and then plug in and try. This many times will fix.

My tv willnot turn on

When it shuts off. Try doing what's called a self-diagnostic test.
As soon as the television shuts try these steps.

Pressing on the front panel's ?INPUT? and ?MENU? buttons at the same time, and holding for 5 seconds,
activates the Self Diagnostic Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem
has occured since the last Initalization.

Please do Note: The front panel buttons must be used, NOT those on the Remote Control.

? The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
? The flashing then pauses for approximately 1/2 second.
? The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
? The Error Code is repeated a total of 5 times.
Example: If the Error Code is ?24?, the LED will flash two times, pause, and then flash four

The Error Code designations indicating a malfunction, or no malfunction, are listed below:
Self Diagnosic Code Description
1 - 2 = no error detected
2 - 1 = X-ray protect (high voltage or beam current)
2 - 2 = Short protect (short protect monitors low voltage supplies)
2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection)
2 - 4 = Vertical protect (usually loss of vertical from the source).
