Ok 7 red blinking led, remove the back cover of the TV. Looking at the power supply in the upper left of power supply. If everything is working fine you will see a solid green led if there is an error, you will see this light blinking also. Right below this led on the power board you will see a list of numbers 1-13 this will give u the problems that this led flashing problems are. More and likely u will have a problem with VSET or VSCAN. Which is connected to the Y-Main and Y-buffers,( the board that is too the left of the power supply if u look on the small print on this board you will see that it reads. 42HDV4 Ymain and the 2 small boards connected to it are Y buffers. To be sure that this board is bad if the TV keeps going into error protection. unplug the power supply and wait for the led to stop flashing. Disconnect the cable that plugs into Y-Main from the Power Supply. It should stay running. If u remove this board and look underneath u should be able to see where this board is getting hot. Easiest fix is to order a replacement. Y-main assembly.

I would check the capacitors on the power pack for failed or blown ones. doing this work will require soldering skills

The most likely problem are two failed capacitors on the main board in the center of the TV The failed parts are easy to identify as the top of the cap will no longer be flat but will have bulged up. DO NOT attempt to remove the back of the TV unless you know what you are doing.
soldering on a circuit board will be required to fix this problem.

TV turns red,shuts off, stand-by light blinking 8Times


Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.

Tv will not come on. Red light blinking on bottom left front. Red light blinks 7 times


I have the model Philips 37PF7320A/37 won't turn on and MOST articles on the Internet say it's the Capacitors capictors capictors..I checked all of them. My tv just blinked red lights, had the clicking sound at first power on, but then goes black. No sound. No picture. Nothing. Just blinking red lights.

MINE WAS RESISTOR no. 3318 , a 100 OHM RESISTOR ON POWER SUPPLY BOARD.

I BOUGHT REPLACEMENT FOR .99 CENTS SOLDER IT, AND EVERYTHING WORKED!!!

THAT WAS ALL IT TOOK.

JUST A SUGGESTION..
1. CHECK FOR BULGING CAPACITORS (90 PERCENT OF THE PROBLEM)
2. THEN CHECK FOR RESISTORS WITH MULTIMETER ( FALLS INTO THE OTHER 10 PERCENT OF THE PROBLEM.)

TELL ME IF THAT HELPS..normanw1@yahoo.comj

Hello, I have recenty acquired a Philips CRT 29PT9420 Television. However. when i attempt to turn the TV on, the light at the bottom of the TV (Standby, On, Off light) flashes between green and red for 2...


Switch the TV on: Press the power switch A on the front of the TV. A green indicator on the front of the TV lights up when the screen is on. If the indicator is red, press the
-CH + keys on the remote control.
The green light blinks every time you press a key n the remote control.

42PFL5332D/37 does not turn on red light flashes 6 times.


Don't have a "solution" yet, but found this table that decodes the blinks:

Error Code Table


0 = No error
1 = X-ray protection, E/W protection, and/or Vertical protection active
2 = High beam current protection active
3 = Reserved
4 = +5V protection active
5 = Signal Processor (IC 7150) register corrupted
6 = Signal Processor (IC 7150) error
7 = Total failure
8 = Internal RAM error (Microprocessor IC 7000)
10 = NV memory (IC7088) addressing error
11 = NV memory (IC7088) size error
12 = Histogram (YUV) (IC 7770) error
14 = Sound processor I²C error (TDA9855)
16 = Main Tuner I²C error (IC 1125)
17 = PIP Processor I²C error (IC 7350)
18 = PIP Tuner I²C error (IC 1127)

I, too, have the 6 blinks of a red light. I found another person online that suggested that perhaps the power cord was "defective" as it's a common issue. I replaced the power cord with one from an old computer (they're the same cord) and it seems to be OK now. That's all I can offer you at this time.
