MrBen10:
Its a small fault, it from the screen lens and can be done by making the lens firmly head to the panel. Tho u can also replace the screen.


To know about how to repair a distorting image on plasma tv, search for it on youtube and carefully watch the video

acunon:
Hi

I can say that from the images above, it may be a panel problem. But if it's not then it's a phenomenon called "freezing" and can be resolved by a skilled technician as it's screen related. Though if it's freezing then it will be a permanent effect any time you put on the TV. Since it's brand new and under warranty I would advise you take it to there service center for prompt solution. Thanks

responding to how to increase the charging current of the UPS.
To achieve ds, a lot of components will need replacement like the transformer, the mosfet, resistors, capacitors e.t.c...so achieving ds is almost impossible. The chances of it been possible is <20% for the circuitry config of the UPS

though you got on my nerve with your reply to my comment. I can say I to some extent see things with you now. I had very good reasons for my reply and I dont think i came off as rude in anyway, we in this field have the experience of people who greedily never want to spend a dime on anything. Anyways with regards to your question, the best person to raise a detailed and accurate bill still remains a QS. but if you want to know if you are being extorted, the answer is no. Actually i have doubts that the cost listed would be sufficient to achieve a quality job, especially if he didnt give clause for revaluation. Just watch out for the quality of materials.

mrnuur:
too greedy don't wanna pay for professional services so they come on here seeking unnecessary attention and mods will jst push it to fp knowing fully such persons if at all they're serious they should consult a Qs

einsteino:
if you arent comfortable with a price, then very simply find another person/firm. This whole idea of getting consultancy services for free is quite unimpressive. I don't know of any other sector outside building/construction where this is obtainable. I cant simply fathom why anyone in the profession should render any of his service for free. If in the end the prices you quoted were outrageous, I would understand. from what I have seen so far, it isnt. You can't pretend not to know that you can hire the service of a Quantity surveyor to vet it for you. I am an Engr and it would be unfair for me to make mockery of another professional by offering his service for free, it is not a nice thing to do.

Suoer Charges are really messed up.
I cracked it open and tried to diagnose the fault .
The circuit design is rubbish,very little safety and protection for the components.

I taught about this laptop charger idea before buying the suoer .
Even without the dc to dc converter it would charge your battery,but slowly since most laptop chargers can give about 3.5 to 5A maximum.
And most of this DC-DC modules are very scarce ,when they available they still have a max of 4A ,so no difference with the laptop charger .

Another option is hooking up the laptop charger to the solar panel input of a solar charge controller (since they are considerably cheaper than the AC chargers). Theoretically it should work ,and there would be little chance of burning or damage to the controller ,since its taking in only dc ,what might get damaged is the laptop charger (which is cheaper to replace ).

BUT i predict a lot of overheating ,since the solar controllers would want to pull as much currents as possible .

I should have just built the circuit myself as i initially wanted ,I was thinking its better and safer for the battery to get what so called "advance professionals" have designed mtcheew.And time constraints to.

Now 15k is burnt just like that.

where did you get it the guy I asked has been telling me he has not gone to market.

the max charging amp is 5amp

kennypedia:
over charging causes hydrogen gas to build up inside the battery it will cause swelling and if care not taken explosion

kennypedia:
the green light doesn't stop the charging process which means you have to unplug manually

vansledge:
the price of that smart charger is 25k now o... so for those buying now is saving all the way o.
back to my question: what if am not at home and i plug it on NEPA light (it got filled b4 i com back), because i no 1 burn person house o
apart from showing the green light sheybi it wont over charge the ba3?

vansledge:
pls this DC step down device, is it smart enough to stop charging when the battery is fully charged?

kennypedia:
Actually yes . most repairers don't actually know the device only few do. did you say u have gotten the step down?

kennypedia:
go to these radionics and electricians tell them you want to buy DC step down

kennypedia:
yes there are various brands its a dc step down . it is needed because the charger itself is 19v. any volt ranging from 12 to 13.4 is suitable for 12 v batt

teamsynergy:
I have the 30a charger too, tho still works. try check the fusible resistor with a multimeter, it should be in the range of 10ohms...if datz is not damaged, maybe d ic is gone... a sizeable transformer and a rectifier would make a dumb charge, making it smart is the challenge. am sure we can work somfin ooo.... I have to d more research tho..


https://p.globalsources.com/IMAGES/PDT/B8817589701/Fusible-Metal-Film-Resistors.jpg
the resistor is usually at the live terminal

teamsynergy:
sorry bout your charger. Have you tried to open it to see watz wrong, perhaps a blown capacitor or bulging capacitor, the fusible resistor and other tiny components there.am sure u r somewhat techy, thatx y am asking all this.... anyways we definitely have to start troubleshooting this chargers and maybe thru that, we could develop our own programmable multiphase charger or a simple durable charge that won't over charge ...



r u sure that ur inverter is designed charge DAT type of battery? cos the stated current is more than sufficient oooo.... but some inverters r jst from hell, they can cause a serious nightmare
