7 blinking red lights. Opened up backside. Do not see any bulging capacitors. Tried different power plug. Same red blinking lights. For anyone in my boat who posted in the past, what is your situation now?

Don't know what to do ... would hate to throw TV out for a $10 solder/replace job ... but it's only that cheap if I can zero in on the problem ... unfortunately, I am unable ... seriously bummed ...

For the hairdryer technique, what part is it that you are heating?

Default Philips plasma tv red blinking light

I bought 4 capacitors 3300uf 10v on ebay for $8.63 including shipping. I install the 2 capacitors on the mother board and now have a green light instead of the red blinking light (7 times). But I have 2 thin black vertical line in the picture now and they stay in the same place when changing stations. Any thoughts on what is causing the lines?

I know this topic is old and could dead but would like to add a few things.
1. the power/mother board what ever it is that have the bulging capacity could be purchase from partsAmerica dot com AKA Bestbuy for $280. Philips dot com $200 (they charge core for $100) and ShopJimmy dot com for $89.00.
I had the same issue with 7 blinking red light, replace the capacitor, different cord (dont know why would this be an issue). and finaly a new board. Nothing works.
Looking into a new tv 42" is just $399 w/ 1 year warrantee.
Unless there is a Philips tech here could details the blinking and what is it indication. I'm at a loss for 1 whole month working on this issue.

Thanks in Advance.

All these Philips Ambilight TV's that were recalled for capacitor problems continued to be manufactured w/almost the same identical recall #s . my 50pf is off by 1 digit and 1 letter - with the identical recall problem. They continued to "finish" manufacturing this batch of recalled TVs and duped the public into continueing to purchase these defective TVs and then stopped selling them here. In effect, just like the snake oil salesmen, "Got the hell out of town".
I purchased my piece of crap in March, 07, in my 2nd home, using it only a few hours a week and "ALWAYS" turning off the power strip - which is why it lasted 4 yrs before "the 2000 hr problem w/capacitors" happened . . ....fraud
It's almost comical that I watch my $100 27" Daewoo, purchased over 10 yrs ago and I have another similar Magnavox
purchased used over 10yrs ago for $50, also w/o problems - but my $2,000 "state of the art" can't make it past, in effect, "one" years worth of watching (5 hrs X 365 days) . ....Hey, they let Wall St sell Billions ofworthless derivatives and we also ran up home values over double "real" value with no regulation . .... so, why not allow Philips to slap us around too ???

Default Lost with 13 blinks!

Obviously new on this forum, but I have a TH-42px75u. Today I got to stare at 13 blinks of the led and have no idea on how to repair, or if it is even repairable.

Any help would be greatly appreciated!

OK back with some update.
6 blinking red light indicated something wrong with the power supply board. Try to replace the 2 capacitors.
Philips Power Supplies, Power Boards & Flybacks

7 blinking could be an issue with the Y board. As of reading and reading from tons of site and Youtube.

For those who got 6 blinks, that should be your answer. I got that TV working with replacing the 2 Capacitors. Works for 1 of mine broken Philips Plasma tv, the other one, if you put in a broken power board, it will blink 6 times, put in a new working power board it will blink 7 times. It cost too much so I dont know when I going to continue with the trouble shooting. $125 @ jimmy and $236.21 @ PartStore.
Hope some one have all the blinks indicator. It would do us good.

I have fixed a Samsung TV in the past with a couple of bad caps but my Phillips has no bad caps (that I can see) and the lone green LED on my power board stays on (no blinking) and the LED on the front of the TV stays solid green as well. NO BLINKING RED LED. I hear a relay click on the main power board when I press the power button and I also can hear the speakers pop every so slightly. No picture or sound though. I also checked that I was getting proper AC voltage delivered to me main power board.

No picture or sound.
No visually bad caps.
No red LEDs.
Green LEDs are solid.
No blown fuses.

Also, the relay clicks when turning it on and off. I can get the relay number if that actually helps.

Strangely I got the same, 6 slow blinks, 3 fast blinks...
Clicking noises from some relays.
No bulging from ant Caps at all that I can see
but, there is always a but, the power board is burned...
I think it might be it as all the caps look OK
I'll go to an electronic shop tomorrow see what they can do about it ....
TV is a Philips 42 plasma ambilight.

Hey all, new to the forum here.

I have the 7 blinks but think it may be a problem from power to the Y main. I have had 3 different y mains in there (connected with buffers installed and not. And no difference. If I unplug the Y main, I get a solid green light. But when plugged in I get a 7 red led and a 13 blink error on the power supply.

Now I notice that the ceramic fuse does not give me a reading after I test the power on. I think I am having a problem from power to Y main. But there are no bulging caps.

Any ideas?

I too have the dreaded 7 flashing red lights (on a Philips 42PF7220A with a Samsung board). Opened the back and discovered C8042 (50V, 680uF) blown, but not the two usual suspects (10V 3300uF). Followed advice from this thread and purchased replacement caps from Digi-Key.

I'm not great at soldering, but gave it a go. No joy. Further testing revealed an interesting anomaly:

When I test (using DMM) the replacement capacitor standing alone on the table, it seems to be functioning fine (number gradually increases). When I put the replacement capacitor on the board (i.e., leads in the through holes), it flatlines with no increase. Jiggering the leads around sometimes gets a positive test, but usually nothing.

Tried soldering again to see if I could get it to stay in a "good" place. Again, no joy.

Checked other caps in the board - C8037 (next to C8042) also registers nothing, but the rest (including the usual suspects) pass with flying colors.

Oh, and did I mention, I seem to have knocked off one of the soldering pads too (although I still have it).

I would welcome any suggested fixes, even if the best answer is "take it to a shop and let someone else do it."

Default 42pfl5522d​/05

i too have this problem with model number 42PFL5522D​/05
i get 2 red flashing lights under the manufacture error code this is:

2 red lights = +12V protection error. 12V missing or "low".

i take it this is a problem with the main psu
someone is selling a complete psu on ebay under this heading:PHILIPS 42PFL7962D/05 TV PART PSU POWER SUPPLY UNIT BOARD 3122 423 31942 (DD26) if you would like to take a look at the psu board

id rather just try to fix the problem myself but not sure exactly where the problem lies
............
thanks for any help you can offer in advance
