Sounds like the internal cooling fan is noisy. Those fans often go noisy on these fluke scopes. Also the charger input sockets fail often, too. I have several fluke scope meters and repaired the charging socket and fan issue on one of them with a video showing how I fixed it. Mine are colour versions of the fluke scope meters but very similar to the black and white screen versions. Lines across the screen is another common issue with that scope meter. If I remember correctly mine work off the charger without the battery installed. Well done repairing that one, good job.
I have the 199c and 199b, they should be similar as far as DC operation they are just higher bandwidth (200 Mhz). both units will run on AC adapter with the battery removed or fully discharged
@@electronicshaverightstolive i have the same problem... i tried with a temp jumper and it runs on AC without the battery but it doesn't work with tha resistor open
@@JohnOud-y6e hello, I think sending device to me won't be economicly reasonable for you because I live in another country and shipping price will be quite expensive.
Ese osciloscopio no sirve a los seis meses de haberlo comprado se. Daño la batería Después se fue aclarando la pantalla y quedó manchada lo envíe por garantía y tuve que pagar ,200 dólares y se volvió a dañar no compren eso se lo digo a todo el mundo lo peor que ha sacado la fluke
Excellent repair and interesting vid! Thank you.
Thank you.

A engineer is someone you shouldn't trust with a screwdriver. Good work
Hi, i have a problem with this scope, It dont work in oscilloscope mode, Someone can please help me ?

That seems logical. I didn't try to power it on with AC adapter after replacing the resistor and with battery removed. Probably it would work too.
@@danblankenship5744 good point.

By the way its really hard to find that DALE R15F resistor.. im still looking
@@eduardovelasquez2142 did you find a resistor I need one to
Its not smart to put li-ion pack without proper bms ...
Yeah. Good point. 100% agree
Hi, thank you for the video. Great job where I can find that resistor.
Hi. Thanks. You can find it on Aliexpress or any radio shop.
Old battery pack was a Ni-Cd but new is Li-Ion .Never don't use without Battery managment system with this new cells ..
There is a schematic fluke 434?, won't turn on.
Нет, схемы к сожалению нет. Ремонтирую девайсы на основе знаний общих принципов работы)
Hello,
I have the same Fluke and the same problem. Would it be possible for you to contact me in order to send it to you please?
Thank you very much
