Thank you, because of this video my 32 inches Devant is now working.
Nice work!
Hello I'm from Thailand , I like to see your several videos clip.
Good information sir
I assume adding this board would disable any backlight dimming? (brightness control)
hi im from Philippines, thank for the information, keep up the good work... bro...
Thanks it's very helpful video
Very nice sir
this video is very useful for technicians
Glad to hear that
Thank you boss it's theoretical and practical information
GOOD WORK
very gooood
Nice knowledge sir
Sir very help full ...... For us.
Bl on ka resister number kya h
10 k from 12v ,
Super information thanks
Sir ye double coil ke driver me 12 or 12 or ground se chal jata h na ya jada power chaiye??
Very nice super work
Very good video! I was wondering what do u mean by checking voltage between input and output... I try this and the board work for a minute then fet burn, there is something wrong with the voltage?
Thank.u very much brother
bon courage jaime bien tes vedeos
Hi from México city 👏🙌
very good video for me give me many knowhow ever
is no more diference between input and output voltaje? I do not understand that part
Sir
I have a led tv of 40 inch.The display is ok.But backlight is not turning ON.Checked all the LED Strips all are ok.
The board is all in one. There are two port .I am getting around 40v on each. But the led strips are not turning ON.
The board is inbuilt.Can u tell me the issue.
40v isn’t enough for backlight boost so You have to buy a backlight tester & try to find....strips are taken properly load or not...
Thanks for your explain. Of i am subscribe of your channel mostly following your channel so I am needing from yours if you please maybe helping iwant how could I disabled protectio backlight for sharp led tv led model..lc40le 185m .steps wiring with new inverter. ..thank you so much for your explain.
Thanku sir my problem is sollu
Very nice
awesome work daju👌👌
What is the value of the voltage going to the led's
Thank you sir, it works.
Led, LCD TV repairing book can be found sir ji
Good job,,,very nice
Knowledge Ka Khazana.
Very useful thanks
Good so best for work
nice tutorial but how to make the BL ADJ to work sir?
Sir without inverter board k short nahi karsakte kya..
Thinks sir
Thank you so much. I'm following ur channel for my improvement.
Good video thanks sir
Nice
Superb vedio
Sir, universe boart to kitina rupes hya
Enable 12v is not ok for lamp card you should take 3.3v as enable from T.con of screen panel
What for resister fixed, how much the vale
Do you have Panasonic led tv TH-L32SV6D mother board? How much rate?
👍👍👍 NICE JOB...
In this case if you have another mosfet from higher voltage old spare board you can replace the backlight mosfet and the capacitor. I did it many times
32 inch TV which board good. 1 coill. Or two coill board
Exelente solución
Super Sir
Nice video sir
Nice video sar
sir ,using pfc circuit ,can we use board
Hi ji onida hd led tv 29" motherboard kedaikkuma
Sir gooday my 32 inch led sparc tv doesnt light the strips i installed i buy universal led driver my input voltage is 12v my BLon is 5v but still the output voltage is 12v it cannot light the strips cant u help me sir ty more powers to u
Make sure your backlight strips are good, connection are properly etc... if still not lit ..you have to connect adj (BL dim) voltage also
Backlight Led bulb strip kaha milte hai ?
I have 48 inch sony TV and have used the same board in this video. But the backlight are extra bright so when we watch movies at night the backlight is high. How to control the light intensity of the backlight in this board? Or any other method to do so?
And what is the cost of this circuit board? Please reply
Good job! Please send your connection photo WhatsApp +9779855054737
Thanks Boss
Thank you
Abans 50" tv akaka sarcit vikunanna thiyenawada sir
Sir my led strip 96 volt ki ha agar ma is inverter board ko 13 volt sa on karo to led light glow hogi
Pls tell me sir
No you need minimum 24volt input
Thx sir
Sir bl on ke liye 12 volt se konsa res.lagega
1K-10K
GOOD WORK
We have any chance to take bl on/off voltage from different palce
Yes we can do it
GOOD THANKS
Thanks you!!!
Thanks sir
Why the 10K to 47 resistor is required??
Tq bro
Nice sir
Nice vedo
Good
good
Kailangan po ba na sa 12 v LNG po nakalagay don sa Vcc panel?
Hindi lahat pareho ang supply ng panel.. may 12v, may 5v may 3v pa yata.
My back light voltage is 55v and I don't have any other replace parts can I do anything on this board to help
Yes you can use it
@@VcoreLC it's a proscan 40 inch and the back light does not work with the 55 v
Hi sir
LED 32 INCH KA BACK LITE 1 SECOND ON AND BLANCK NO PICTURE ONLY SOUND ON
ISKE LIYE KYA KARNA HOGA SIR
You have to glow backlight first, with backlight tester....and check video on screen if yes... repair backlight section
Minha teve como logo Led so pisca,i sai mesmo som.
Music bhanda afai bolnu bhayeko bhaye ati uttam hune thiyo ki sir
Thank you Khem sir for suggestion
तर म सवैमा यो गर्न सक्दिन
Sir yo board lai kati jati parchha hola ? please repply garnuna hai.
What about universal board if backlight on, sound on, but no picture. The display blank. I check the 12v LVDS shown 0v, please help my TV, thanks a lot
Check short circuit with panel vcc if no panel vcc switching transistor or fet on board
Para saan po yung resistor idol? 10K LNG po ba yan?
Para sa backlight on ng backlight driver bro.. ang required voltage ng backlight on ng driver ay 3.3v to 5v.. doon kumuha ng supply sa panel which is 12v so naglagay ng 10k ohms resistor para mag drop ang boltahe bro.
Registor volt please
In this motherboard pictures are opposite what to do bro.
Driver board supply volts???
19 to 30 volt resistor 10k to 47
Blon supply resister kitne ka value?
47k
I am punjab
Please explain slowly in English or Tamil as I can understand
I already install the universal driver the input is 12v the bl_on is 5v but still the output voltage is 12v it cannot light the les strips inside pls help me ty very much
There are some backlight driver ordered online happened to be defective. Take note when you install the 12v & 5v supply on the driver.. install right away the backlights too.
Maine ye circuit combo board 40 inch ke sath lagaya lekin jaise hi stand by release karte hain 47 mf wala capacitor blast ho jata hai. Stand by mode mein blast nhi hota hai aur led connector ki pin par 63 volt show hota hai. Maine LED strips ko connect nahi kiya hai, kya ye load na hone ki vajah se hi blast ho raha hai ? Please help.
Backlight driver input voltage?
Blasting capacitor working voltage?
Ye aap ne nahi bataya..
Input voltage is 12 volts. However I could not measure the voltage of blasted capacitor since it happened very fast, within 4-5 seconds.
LED strips connect karne ke baad AC supply on karne par blast nahi ho raha aur backlight bhi jal gayi. Lekin light constant nahi hai flicker kar rahi hai. Backlight jalne ke baad circuit mein 131 volts aur 110 ma current show ho raha. Jo niche ki side mein 6 smd resistance lage hain unhe jumper se connect karne par bhi light intensity ya current mein koi change nahi ho raha, current 110 ma ke aas paas hi rehta hai. 10 led ki 4 strips means total 40 led series mein lagi hui hain.
Sir, too deference between input voltage or output voltage caused this type of problem... if 131v output must have 24to 35 v input..
Kitna ka ha board
Sir full details me bata dijay
Very much
Sir mosfet overheating reason tell me sir, how can I solve it?
Too different between input & output voltage
@@VcoreLC thank you so much sir, can I increase input voltage?
hello sir you can also connection 2nd mostef to main driver supply
above 32 inch led tv in use
Ye normal folt hai
Not suficient this backlight in 32 led, in this volt uotput is 90volt, perfect volt to 60v in32led actually this backlit is 40inch led tv
10k nahi lagaye to kya hoga
تساهل
Ok
Jaise k backlight off na ho
Backlight on ka wire kha connect kiya samjha nhi
LVDS cable vcc point
