Question about Philips 47PFL7422D/37 Television

Open Question

47pfl8404 two days old-DEAD!

Tried to switch on this morning and the Philips logo comes up as usual, then screen turns off and white light just blinks continually. Tried unplugging for a while and plugging back in but to no avail. I guess this is the main board, but could it be caused by adjusting the service menu? Surely not? I know they warn you against this but surely there's nothing that should do this to the tv? It was working fine all day yesterday until I switched off last night. I'm just worried that they might be able to tell I've been into the service menu and not refund my money.

SOURCE: My Philips 19pfl3403d/f7 wont turn on without unplugging first.

just call philips and they will send you a new t.v.! it isn't a recall, that would be bad publicity!! i spoke with a philips representative yesterday concerning my 'possessed' television. a gentlemen informed me that philips has a 'rapid replacement program' for the described 'possessed' t.v. set. simply provide model and serial numbers, time and place of purchase, then provide street address for fed-ex delivery. approximate time of arrival is 10-15 days. you are directed to package and return the old set to nearest fed-ex pick up site. i am super excited that i took the time to call philips support. i think that i spent a total of 10 minutes on the telephone; it was time well spent. oh yea, here's the number!

SOURCE: Red LED blinking after turn on the TV (Philips Plasma 42PF9631D

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

SOURCE: Hi. My Philips flat TV will not show any picture

I had the Same issue. on a 50PF9431D/37 set. Many Plasma Set's use a LJ44-00118A PS-505-PH Power supply from Samsung. Known to have this common problem. If you can, or have a friend that can Solder components?. Unplug your set remove the back panel & locate your power supply. It will be the PCB in the center of the set just above the Video/Audio connections. http://www.shopjimmy.com/power-supply-unit-lj44-00118a-from-philips-50mf231d-40.htm. Is a Link to a photo of the PCB. Make a note of the locations of all cable connections then unplug them all. Un-install PCB, Check all Fuse first. I believe their is 5 or 6 of them on the PCB. Then replace the two 3300uf 10v 105C Radial capacitors at C8060 & C8059. Look to see if the Caps are deformed and or split at the top. The location of the caps are in the Lower bottom edge of the PCB. A local shop may Carrie them if not, digi-key has them. Part # http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=493-1754-ND. Total cost was $7 with S/H.

Vizio M650VSE powers up, pilot light comes on, logo comes on screen, 10 seconds later, logo goes off of screen, pilot light goes off then flashes 1 time. Which board has the problem?


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://electro-medical.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.

hi there!

try changing batteries. or try turning it on while charging, if theres no problem when its directly plugged in with the charger, the battery may be dead (especially if its more than a year old and is frenquently used for calls and internet). if its having the error while still plugged in directly with the charger, a local technician is the best here.

The standby power supply resistors on the inverter board have changed values. You will replace resistors R1217, (820K 1/4 watt), R1218,(820K 1/4 watt) and R1219 (390K 1/4 watt). Please use the values just mentioned. Or you may have the inverter board replaced. Take this note to a TV repair Tech.Thanks for asking and show a few hands of support!

LG 47" LCD shuts down several times w/ blinking red light.


Granger1212 we had the same problem. We called LG and although our LG was out of warranty by 4 months, we were asked to supply our proof of purchase and LG sent a serviceman to our home and in 2 days we had our television back working wonderfully. It's the power supply, call LG and BE NICE, I'm sure they will fix it.
