- This is 50” Hisense Smart Tv. In this video I replace two of the capacitors that were blown. Let me know how I did.
Exact capacitors I used:

The video that teaches this way better than I can:

Update**** it has been 4 months… tv still working!!!

This is nothing more than a recall when it becomes a pattern. Thank you Amy.
Just a couple pointers
1. Get a desoldering gun it will melt the old solder and suck it up so you don't have to fight with getting the leads into the holes
2. Do not pre-tin the leads on the capacitor it makes the leads thicker and harder to get through the holes.
3. Do not trim the leads before you solder the capacitors back into the board keep them long this helps with alignment just insert the leads and push the capacitor down to the board as far as it will go don't force it then on the back side of the board put a slight bend on both leads at the board this will hold capacitor in place long enough for you to solder
4. Also when discharging the capacitors it's recommended to use a 20k ohm resistor across the capacitor terminals this is much safer than a screw driver
Agree on all points…
Capacitors went bad after a storm. This video showed me all I needed to know. Took about 2 hours as I had never soldered before. Thank you!
Where did you get parts?
Good job ❤️👍for someone who doesn't have much knowledge about electronics.
Careful🙏 before discharging capacitors. The one you discharge and make a big spark was the high voltage capacitor ⚡🖐️.
It's was around 350 volts. ⚡.
To discharge a high voltage capacitor you need a resistors. Around 220 omh.
It's not safety to discharge it with a screw driver.
The soldering must heat enough so you can disoldering the joint on pcb easily.
You must heat the old soldering on the board with new soldering leads. Then it will be easy for you.
If not you can use desoldering pump vacuum also.
Next when replacing the new capcitor no need to cut the pins. Just insert it and afrer soldering on the board you can cut it.
Never add soldering leads on the capacitor pins before inserting it on the board. The hole on the pcb is so small. Overall it seems OK if you had inserted the capacitor correctly in the direction needed. But I seen the soldering is a bit loose. You need to apply it near the board.
I have a hisense tv also.
🙏😊 Nice to see your TV working.
Well hopefully it continues working and I don’t need to replace them again. I shouldn’t have turned it on right before I started, but I wanted to film what the tv looked like before. It had a pretty good spark 😀
@@echoingamy well if you didn't turn it on to film it. So everyone wouldn't the problem of the TV.
Don't worry you replace it well as I seen on the video. It will work for a long time. The capacitor don't get blown easily. Unless there are some other factors make a capacitor blown. The diotes or if a lizard 🦎 come on the power supply that's cause much troubles.
When I seen the spark I was shocked. As you can see the capacitor keep some voltage despite you turn the TV off.
Be careful next time please 🙏.
Me too I didn't know much about it. But I learn it when I had experience this for the first time.
Just be careful please. ❤️
for a woman, you did it! that's having courage keep going! greetings from Bolivia😘
Your first time and you all those soldering techniques 😮
I just wanted to say thank you. I had an issue with my 70in ONN TV, and this actually was the problem. I will be tagging you in my video.
if you power your TV directly in the wall plug and don't use a proper "surge protector" power strip (it must say "surge protect" or "surge suppress" on the power strip), then a storm or sudden surge on the power grid can blow the capacitors. ALWAYS run your more expensive components, such as TVs, audio, PCs, Laptops, Roku, etc. on true "surge protectors." APC and other companies have really good surge protectors. Some folks plug into a power strip that are simply a "relocatable power tap" that don't have surge suppression.
Mine was plugged in a surge protector strip and still blew the caps... It's a 4 year old Hisense, not sure if age is involved
👋👋 well done..a good effort ...just a few things which have been mentioned,
personally I also like too make the sponge a bit damp.
Thanks for the tips!
This is insanely impressive. I've never been brave enough to fix an LCD Panel. (I think an O6's tv broke and nobody wanted to take it apart because of the capacitors!)
I think the only thing I successfully soldered was a CAC reader that had cables that kept coming loose.
I would caution that most "Tin" has lead it it so you would probably want to wear some type of gloves and work in a Very Very well ventilated area and wear a mask too.
It’s fixed, but I’m too afraid to use it. I need an electrician to watch it and tell me it’s good enough.
@@echoingamy You could use it in a brick area or other non flammable area.
I'm an electrician / electronics technician and, except for the very first cap, you did really well - even that first cap gets a passing grade of B-
@@ValleyDragon stop giving misinfomation and making people dought there work! there is not a lot to go on fire in that tv! they replaced the caps just fine and the tv is great again!
learn some more about electronics before you comment, you know, so you dont say stupid things.
@@echoingamy use it all is good, you did just fine, the back light is back and it works again yay
No need to tin the cap legs, it makes it harder to fit the cap legs in the holes, also before you remove the old caps add new solder to the pins 1st, this will help the original solder to melt quicker.
Good job for a girl I have the same tv same problem same blown capacitors wish me luck
you can do it! dont be a beta!
Thanks this helped me fixed my 55 inch Hisense Roku tv.
Great video. Same problem. You are very wise. Thanks for posting.
Thank you
Thank you for this information. I replaced two of mine and it works perfectly. I put two 400 in mine replacing the 350.
Awesome
As an engineer this was funny to watch it reminded me of the labs we would do in college😂😂
great video, i had same issue with my tv but didn't fix mine.
Sorry to hear that
I know this post is old but next time try checking the backlight LEDs because if one fails then the TV will come on for a few seconds then turn off
@@georgec7798 I should've done that, but thank you for reply.
What if the capacitors are not puffy up top?
I have what appears to be a similar tv. No blown capacitors, no screen, and blinking red light (faster blink than yours). Still diagnosing.
same here, red light blinks twice..This is my second Hisense, the last one did the same thing.
Same thing here. Changed out main board/power board didn't do anything. Was thinking of changing out the tcon board. I'm just not sure that is the issue. There's no hard reset on my model 50A6G already a hundred dollars into the repair any suggestions?
My capacitors did not look blown. I replaced them anyway. It ended up being the problem.
@@charlieelifrits1889did u ever figure it out? same issue
@@charlieelifrits1889 could be a faulty backlight array
Thank you
I fixed my TV watching you. Queen Shit👑❣️
Yay
I have a vizio tv I had about four years. when I Purchased it I was Browsing through ebay and they had 65 inch like mine that had a cracked screen they were selling all the circuit boards out of. So I have all brand-new circuit boards in a box in my office closet. I hate to throw anything away so I'm going to replace the Capacitor's and put the new one in and save the old one as a spare.
That’s awesome
Great tutorial amazing
Thank you
What Hisense model was this? Thank you.
Respekt die Frau hats drauf Mega.🤗🤗🤗👍👍👍
what if u have changed capacitors & tv still does same thing?
Wow smart lady
thank you
do u have to take every connection off for new capacitors to work
LOVE UR VID
LOVE UR STYLE .

👏
& SOME.
Thank you
can you tell me capacitor model thanks
Te falto la pasta de soldar y un extractor de estaño manual
เก่งสุดยอดครับ
Hi @echoingamy could you please share me the link to capacitors that i need to order and also the soldering machine
The exact ones I ordered are linked in the description box
Do you know the model number of the TV
Good video Thanks
I don't know sorry
I now have two tvs with blinking red issues, I wish I knew how to test if it’s the capacitor or circuit board or power , do they sell a testing kit for tvs to learn?
Not sure
@@echoingamy if you see any caps swolen or domed then they need replacing! if its something else then you would need to learn more about electronics in order the repair deeper.
Wow well done girl, very nice, and your voice are beautyfull, a hug from mexico 🤍💚❤️
Thank you
COOL👍
could these capacitors go bad without "swelling"?
Yes. It’s affordable to replace so it’s worth trying. I’ve replaced them twice.. second time they looked perfectly fine.. replaced them anyway and tv worked again
Sir , my self mayur redkar
Three time light blink hote hai to kya issue rhe gaa
Have the same problem with my tv but none of the capacitor are blown like urs?
Idk
Is the sponge wet?
Yes
Bravo 🫡
Where did you buy your tool & capacitors from?
Amazon
Link?
Use the heat on the solder to get the grease off that oven.
Replacing the board is only 39 dollars.
Where can I get that??
The flux capacitor is broken
i have a red blinking light but not displaying anything on screen any suggestions?
I’m not sure
omg thing almost shocked her. ima try ta do this for my fcked up tv
É condensador chinês não dura nada
Mine doesnt even show the hisense logo
blew out her compasiter XD
