    I just installed this new board (the one with the inputs). With the original one, the BLUE regular power light came on as usual then it would turn off. I replaced it (the board wth the inputs) Then I got the 6 red flashes (after installing this new board). I am wondering if it (the board) needs to be configured or is the board actually bad. I see no bubbled capacitors. Do you know specifically what the 6 red flashes mean? Thanks.

Hi

Thanks for using FixYa. From what you have described it seems the issue is with the power board or the main board and we'll need to check few things. When you open the unit up; take a look at the power board-the board where the power cords/plugs goes into. You might see some filter capacitors a little bulged up in the top-If this is the case-this is your defective part(you can try to replace them-but some soldering equipment is needed). If not, then probably the main board has gone bad. This is the other board-where all the inputs are going into. All this is only recommended if you have electrical expertise and know how to solder/re-solder components. Please note that the TV components consists high voltages even when in off position. Please accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

LED Indications

The front panel Status LED provides an indication of

the set's operation and the possible cause of a malfunction.

If an abnormal condition is indicated, perform the

Self Diagnostics procedure.

Self Diagnostics

To activate, press the front panel <ACTIVITY> &<CH

??> buttons at the same time and hold for 5 seconds.

The STATUS LED will then flash denoting a two digit

code.

• 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

(ones digit) of the Error Code.

• The Error Code is repeated a total of 5 times.

Example: If the Error Code is "23", the LED

will flash two times, pause, and then flash three

times.

Table 2-2: LED Indications

Error Codes, descriiptions and the most likely cause of

the error are listed in Table 2-3.

Note: The TV must be in "Shut Down." The LED

will probably be indicating an abnormal

condition. If the TV is switched Off, AC is

removed, or a System Reset is performed, the

code automatically resets to "12" No Error.

See the Error Code Log to retrieve a history of

errors.

Note: Use the front panel buttons, not the remote

control.

Note: If there is no response, the front panel may be

locked by a V-Chip setting. To unlock, press

and hold <ACTIVITY> on the front panel for

8 seconds.

LED Indication Condition

Off Off (standby)

Green Power On

Slow Blink Green Power Off with Timer Set

Fast Blink Green (80 seconds) > Off Power Off (Cooling fan still working, 80 sec)

LED Indication Condition

Red Lamp Failure

Yellow TV Too Hot

Slow Blink Red TV May Require Service

Slow Blink Yellow Lamp Door Open or No Lamp Installed

NORMAL INDICATIONS
ABNORMAL INDICATIONS (For details perform Self Diagnostics Procedure.)

Sony kdl46ex500 red power light blinks six times


Most probably there is a problem in the power supply and it is going on standby protection mode. You may have to search for a service manual from open websites and look through for the error code indicated by the led blinking, to be very sure. Unfortunately I do not have one with me.

Philips lists 3 models of your TV:
1) 50PFP5332D/37
2) 50PFP5332D/37B
3) 50PFP5332D/37E

User Manual for your TV (actually for the 50PFP5332D/37E):
http://download.p4c.philips.com/files/5/50pfp5332d_37e/50pfp5332d_37e_dfu_aen.pdf
The user manual doesn't document the logic board blink codes for errors.

What this tells me is that the TV went thru two revisions before reaching version E.
in case it helps: Philips Customer Support: 1-888-PHILIPS.
If they can't help otherwise, they can at least tell you if your set is eligible for warranty service.

My philips tv flat screen keeps shutting off and a red flashing code starts blinking?


Not sure what code since you didn't say, but here is the code breakdown.

When the TV does this, the RED LED on the front will blink. For digits 1-10 it will blink pause then repeat. For numbers with 2 digits it will blink the first digit slow and then second digit fast. So 25 would be 2 slow blinks followed by 5 fast blinks.

Philips 42PF5321D/37 Plasma No Picture Six Red LED Flashes


Those 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.
http://homenol.blogspot.com/
http://electronicshelponline.blogspot.com/
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.
Counting of number of blinks to Philips TVs is entirely different to that of other brand TVs. It is not a direct count procedure. The site have details about how to count the number of LED blinks [Fault Codes] to Philips brand TVs are given; along with details of the faulty circuit location.

Philips 42PF7220A/37 Chassis Number BP2.3U


I think its something on the picture frame board or on the line output board. I would sway to the line output simply because I think but not sure that error code is linked to the line output stage plus when you unplugged the cable the voltage seems within parameters. Good luck.

Most likely the YSCAN UPPER board and/or YSCAN LOWER Board also gone. Your new YSUS board may damage again if you don't replace the bad YSCAN boards. Try to replace the three boards together and then to verify which boards are bad one by one. Good luck.

Error 7 is a power related problem. This is what u need to do.
Remove back cover.
Plug in power when tv goes into error protection, check power supply and see how many times the led flashes. Right below the flashing green led there is a list 1-13 of error codes and what they mean. Your problem will probably be an error 7or 8 VSET or VSCAN . Which ever error code it gives you VA VSET or VSCAN or whatever it indicates look at the cable connectors to the power supply unplug that connector and the TV will stay on. And there will be your problem.
