LCD TV wont turn on and red LED flashing error code

If I am lucky I can get my 52PFL9432D/79 to turn on and then it seems OK. If I turn it off and then back on again within 10-15 minutes it tries to turn on but after some relay clicking it fails and I get the red standby LED flashing 5 times slowly and three times quickly. If I then unplug it for an extended period, it will usually start after I plug it back in.

It also seems to take forever between pressing the ON button to showing an image. Sometimes it will give sound at start up but no picture. Change channel, and the picture appears.

All help appreciated.

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.

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.

I had exactly the same problem When the TV was switched on all I could see was a flashing green light. After cheching the TV internals and not seeing a problem including the power supply unit which looked and checked normal. Here is what I did to get M TV working again.
Disconnect it from the power supply. Hold down all the buttons simultaneously i.e. the on/off, the volume, the programme, menu buttons, all of them simultaneously and Plug it into the power supply again.
Lo and behold My TV jumped back into life after an absence of about 4 weeks.
Try it yourself exactly as above.

Best of luck.

Two problems: first, tv turns off for about 10 seconds after being on awhile, then turns back on. 2nd, picture will sometimes go black horizontally displaying only half of the upper screen. This will go on for about an hour off and on.

My Hisense 50K23DG T.V. wont turn on?


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.

If blinks continue without any pause, the main board is faulty.

Blinking codes details to many popular brand TVs are given. Surf the site with patience.
Normally continious flashes of standby LED indicates a main board failure. Anyway, count the number of blinks as stated above, and make sure about the fault. Contact any service technician.

Flashing red center light


With most flat panel TVs, the TV turn itself OFF when it has a fail electronic part and the red light starts flashing. They call this "Protection Mode". The flashing red light should be a error trouble code.
But, it's weird that everything is working and the red light is flashing. Since you just recently bought the TV, I would get it check out while it's still under warranty. Better safe, than sorry.

Remote control (UBRC-120) will not work the unit.


I had the same problem. resolved it by the following......
1. Press and hold the TV button until the red LED turns on and stays on.
2. enter 00000, the red LED will flash and turn off
3. test remote
This procedure should put the remote settings in default for TV.

if all goes well remote should operate the TV

Philips 37PF7320A/37 won't turn on


That blinking led is an error code for the audio standby board in the set. It should not go out this soon and yes it should last longer.
