No, and actually KMZ (the plant where Zenit cameras are produced) before the war produced a digital camera, and they still make various types of lenses.

Sorry, "1.5V lead acid AA battery"? Never heard about something like this...

@@dmitrysysoletin9967 Sorry i mistaken,it's zinc carbon and non rechargeable.

You can discharge single cell to 0 Volts, and with small discharge/charge current this will not lead to significal damage. Hovewer, if you will dischage a battery (several cells in series) of rechargeables in that way - you most likely will kill cells in a few cycles - because in a battery weakest cell will be reverse-voltaged in that case. But with single cell this not just harmless, slow discharge to 0 can actually recover some capacity of old cells (but not much, they will not be like new).

Excuse me, what language is this written in?

Maybe you should try some rechargeables then?

Hi there! Thanks for your comment! If you want to have a simple point-and-shoot camera, please consider getting one with adjustable aperture and shutter speed. All (reusable) disposables will be more or less the same - just because they all have a shutter speed of about 1/100s and a fixed aperture of about f/10.

In low power long use devices like clocks i use zinc carbons

In a clock they last at least 1 year with a cost of 10cent per battery

Hi there! Thank you for the question! If the cost is not a question, and you need the longest lifetime (for example, in some sensor where it is problematic to change the batteries) - lithiums will be best. If the price is also important - in my opinion, the cheapest alkaline will be the best choice. Thank you, and have a nice day!

@@filippocara0510 Hi there! A good option for a really low-drain device.. But only for ones with a really low drain.

@@dmitrysysoletin9967 yes that 's true. For high power drain I use ikea ladda 2450mah, for mid drain alkalines and for low drains zinc carbons. I found some really good deals with zinc carbons, like 1€ for 10 and they last long and never leak even when dead

Hello! Thank you for the request. Sure, I will do such testing. Not immediately, but will do. Have a nice day :)

Хай! Тхэнк ю вэри матч фор йоур фиедбаск! Хаве а нисе дэй! :D

Hello! Thank you for your request! Yes, I will do the Energizer batteries test. Maybe not tomorrow, but soon. Please stay tuned ;)

Have you fixed already ?

@@maniekkozlowski Hello man, yes I solved this changing the 4 capacitors like the vídeo, now works good

@@mikytujefe your screen was like visible with flashlight or black black ?

@@mikytujefe my imac is going black screen but when i pres power button for 1sec screen is up again

@@maniekkozlowski Yeah is totally black and When I press power button the screen is back but later turn black again, you can solve this changing the 4 capacitors

Thanks for watching!

Yes, there are capacitors on the power board that can hold a charge (they charged to rectified mains voltage, about 310V in 220V countries) for a while. So to stay safe, disconnect the power cord in the evening and start opening the computer in the morning - give it time to discharge. About the backlight - well, if yours is broken anyway, why not try?

you can just discharge them. unplug PC, and Hold the powerbutton for some minutes. You can double check the caps with a voltmeter. anything below 50v will be safe. if still above you can hold the button more, or just discharge the caps with a resistor

Thank you!

Thanks for watching!

Thanks for your comment! I am glad the video was useful!

Thanks!

Hi there! Can be lots of reasons for that. Bad capacitors is just the easiest one to solve, and for me, it helps :) No, I don't have a link. Just bought some caps in a local radio store. You can do the same, just select ones with equal voltage and equal or higher capacity. Low ESR ones are preferable, and the higher the temperature rating - the longer they will work.

Да, это 27"

Hi Alex. Yes.

@@dmitrysysoletin9967 ohhh nice, i seems to have the same problem ! Very good video thank you !

Привет! Они сохранились, но сказать так сразу не смогу - они в эксплуатации. Сегодня-завтра заряжу их и положу на полочку, примерно через месяц посмотрим, сколько там осталось. Отпишусь, как будут результаты. Спасибо за комментарий и интерес к теме :)

@@dmitrysysoletin9967 Вам спасибо за обзор. Могли бы вы сказать свое мнение об этих аккумуляторах? Плохие/хорошие?

@@_L_L_I_R_ К сожалению, у меня пока нет подборки данных по аккумуляторам, чтобы я мог сравнить эти с другими, и сказать, насколько они хороши. Но могу сказать, что они точно не плохие - в фотоаппарате вполне себе неплохо работают, а он достаточно привередлив к качеству источника питания.

Привет ещё раз. Через 6 недель хранения эти аккумуляторы выдали ёмкость 1690/1723/1652 мА*ч при токах 100/200/500 мА (разброс, видимо, обусловлен разными характеристиками ячеек) при номинале 2000 мА*ч. Не топ LSD, но и не старые Ni-Cd :) По моим ощущениям - неплохие аккумы, и ценник приятный.

Hi! Sorry, I don't remember their characteristics. Just use ones with equal voltage (you can take ones with higher rated voltage, but they are physically bigger as usually and may just not fit there) and equal or bigger capacity. Low ESR ones will be good, and a higher temperature rating - is better.

Hi Rob! Thanks for mentioning that comments were off, I fixed it, sorry for the inconvenience. About your backlit - I can't diagnose it, but yes, the chances of changing the capacitors will improve the situation are good. If it is not a capacitor, then backlit LEDs are dying. Because changing the capacitors is way easier and cheaper than changing the LEDs - I recommend you do so. Thanks!
