I have a Samsung 50PF9630A/37 with red light blinking 7

Customer Question
Hello, I have a Samsung...
Hello, I have a Samsung 50PF9630A/37 with red light blinking 7 times. I changed the suspect caps even though none were bulging on the power board with no avail and still have red light blinking. The green light on the power board also blinks 13 times. Change out power board or trash tv? What else to check?

Power Board lj44-00108c in tv now. A little hard to find. I am hoping that the blinking lights will be able to code the issue. I have electronic training but lost when it comes to tv's. Hope you can help. Thank you

Can you double check the make and model, please? The 50PF9630A is a Philips model, but you post says Samsung. I just want to make sure we're talking about the same TV.

Customer reply replied 2 years ago
Sorry, Yes it is Philips. I had Samsung on my brain
TV Technician: Dan, Master Tech and Repair Facility Trainer replied 2 years ago

OK, and the red LED is flashing 7 times, right? Any other symptoms? Does the TV turn on, then shut down and blink? Or does it blink as soon as you try to turn it on?

Ask Your Own TV Question
Customer reply replied 2 years ago
it will light green for about 10 seconds. Clicks and turns red flashing. There is a green light on powerboard blinking 13 times
TV Technician: Dan, Master Tech and Repair Facility Trainer replied 2 years ago

Power board blinking is fine. Does the screen do anything at all?

Ask Your Own TV Question
Customer reply replied 2 years ago
nothing on screen
TV Technician: Dan, Master Tech and Repair Facility Trainer replied 2 years ago

I always make the room very dark... then watch the screen closely as I turn the TV on. Tell me if the screen lightens up at all...

TV Technician: Dan, Master Tech and Repair Facility Trainer replied 2 years ago

OK. Is this the original power supply or was it replaced? Are you the original TV owner?

Ask Your Own TV Question
Customer reply replied 2 years ago
I am not the original owner, but have had it for about 4 years. I do not know the history
TV Technician: Dan, Master Tech and Repair Facility Trainer replied 2 years ago

OK, and the TV has been working well for 4 years? No repairs since you've owned it? Which caps did you replace?

Ask Your Own TV Question
Customer reply replied 2 years ago
Two 10v 3300uf caps everyone points to in the forums. Cant remember location but it seemed to be common
TV Technician: Dan, Master Tech and Repair Facility Trainer replied 2 years ago

OK if you had a power board issue, those are the right ones to replace. Good work. Problem is, I rarely see 7 blinks caused by the power supply. Usually that's 5 or 6 blinks. On this chassis, it's more common for the Y-sustain and buffers to cause this issue.

Ask Your Own TV Question
Customer reply replied 2 years ago
working well
TV Technician: Dan, Master Tech and Repair Facility Trainer replied 2 years ago

And on these Philips models, you cannot replace just 1 buffer or just the Y-sustain. All 3 boards have to be replaced unless you want to blow something up. The upper buffer, lower buffer, and Y-sustain all go together.

Ask Your Own TV Question
TV Technician: Dan, Master Tech and Repair Facility Trainer replied 2 years ago

Sometimes we can repair them if we see something obvious. Melted ICs, burnt components, etc. on the buffers (upper or lower) or hot transistors / caps on the Y-sustain... you can replace individual components if they look fishy. Otherwise, all 3 boards have to go... if you want the TV up and running normally again. Sorry it's not good news....

Sounds like new tv? I am willing to change out boards but this sounds extensive?
TV Technician: Dan, Master Tech and Repair Facility Trainer replied 2 years ago

Eh, depends on where we can get the boards. Give me a minute... let me see who has them.

Ask Your Own TV Question
Customer reply replied 2 years ago
ok
TV Technician: Dan, Master Tech and Repair Facility Trainer replied 2 years ago

OK, the Y-sustain is $42 (here). Upper buffer is $21 (here). Lower buffer is $36 but they are currently out of stock (here).

Ask Your Own TV Question
TV Technician: Dan, Master Tech and Repair Facility Trainer replied 2 years ago

Keep an eye on the lower buffer and order when they have it in stock. Those are really good prices.

Ask Your Own TV Question
Customer reply replied 2 years ago
Can they be changed without calibration or adjustment?
TV Technician: Dan, Master Tech and Repair Facility Trainer replied 2 years ago

Yep, they're just plug and play. Make sure the power cord is disconnected for awhile before you work inside, and practice good ESD safety (keep yourself grounded to the chassis).

Ask Your Own TV Question
TV Technician: Dan, Master Tech and Repair Facility Trainer replied 2 years ago

No soldering, no fancy tools. Just screwdrivers and some patience.

Ask Your Own TV Question
TV Technician: Dan, Master Tech and Repair Facility Trainer replied 2 years ago

I would replace them for those prices. Usually they're much more expensive. If you have any other questions, just ask. I'm online most days, usually in the evenings.

Ask Your Own TV Question
Customer reply replied 2 years ago
Prices are cheep enough. Would you recommend trying this before scrapping the TV? Sure its not the power board?
TV Technician: Dan, Master Tech and Repair Facility Trainer replied 2 years ago

Can't be 100% sure of anything, honestly, but it's highly unlikely that the power supply is the issue. When they fail in these Philips models, the caps almost always swell up. Even when they don't swell, it's those 3300uF caps but you already replaced those. The only other real possibility is a scan board, and all 3 have to be replaced together. I think you're safe, and yes I would replace them before scrapping the TV.

Sounds good Dan. I will give it a try. Maybe ebay will have the last board. I will use your links for the model numbers and get some on the way. Thanks

Dan. The first board
996500030030 PHILIPS TV MODULE, Y-MAIN, LJ92-01046A, LJ41-02317A, 50MF231D/37, 50PF7321D/37
Does Not list my TV model number. Is this the correct board?
TV Technician: Dan, Master Tech and Repair Facility Trainer replied 2 years ago

Yep it's compatible. You can also use BN96-02025A but it's quite a bit more expensive.

Removed the boards now. Online ordering. Thank you
TV Technician: Dan, Master Tech and Repair Facility Trainer replied 2 years ago

Used boards are definitely OK, just make sure there's a warranty. ShopJimmy.com and TristateModule.com are good used/refurb sites and all their parts are warranted.

Hey Dan, Received the new boards and will install them Sunday. Keeping my fingers crossed. Will let you know if that fixed the set. Thanks

OK no problem.

Customer reply replied 2 years ago
Good evening Dan. Installed the boards and nothing changed. Back to the 7 red lights. It tries. Powerboard clicks, the two green led's at the bottom of the power board light, after about 5 seconds, clicks, they go out and red light flashes. Like I mentioned before then a green light on the power board located on an extension board on the upper left side of the power board just under two big caps flashes 13 times and continues to flash. What would you try next?
TV Technician: Dan, Master Tech and Repair Facility Trainer replied 2 years ago

Interesting. I actually don't recall seeing this before. I'll opt out, which will allow the other experts here to see the issue. If they can help, they'll post here and you'll be notified. No need to rate the service you've received thus far, as that may prolong the time it takes for someone else to help.

Thanks Dan. Hope $123 later I don't want to give up quite yet. Even though I replaced the caps on the powerboard maybe it is still the culprit?

I have three Philips DVDR75/17 dvd recorders with very few hours of use on any of them. They all play DVDs of movies but none of them record DVDs as they are supposed to.
