Would it be possible and safe to bypass the 5v pwm regulator circuit and replace it directly with a 7805 regulator instead? Thanks.

This external power supply should be switched as it did on subsequent models or there should be an internal protection circuit that protects the motherboard against extreme AC variations. Then I conclude that either the engineer was negligent or incompetent or even was conniving with the korg's intention to create a trap for users with the intention of selling new keyboards to the unlucky ones that would cause them to be burned by plugging the psu into 220v. There are thousands of keyboards from these bottlenecks around the planet that should have been working to this day like many other older korgs. If they were honest and respectful of their users they should have made a recall so that the authorized repair shops installed internal protection on the boards or continued to manufacture new replacement boards already with the correction of the problem thus causing their eternal survival. If the keyboard is so good in all aspects, why did the power supply have to be bad? Unfortunately the users are not united and demanding because if they would have made a class action against korg to require at least receive a new mainboardAnonymoushttps://www.blogger.com/profile/17023231608635067842noreply@blogger.comtag:blogger.com,1999:blog-407728728590426370.post-83303566987906337512016-02-17T02:46:09.776-08:002016-02-17T02:46:09.776-08:00which terminal of the adapter carries 9v and 5v he...which terminal of the adapter carries 9v and 5v help pleaseAnonymoushttps://www.blogger.com/profile/12828757384991413402noreply@blogger.comtag:blogger.com,1999:blog-407728728590426370.post-39770276953238377022015-09-07T20:42:37.971-07:002015-09-07T20:42:37.971-07:00Thank you for this information my korg le 61 the ...Thank you for this information my korg le 61 the buttons combi or program is flashing.As when the light does not have power But in the part of the smart media card is hot and I opened it is very hot the coil and this distorted sounds please i need help I want to know the value or how to order diode smd is 3132radiolavozdesalvacionhttps://www.blogger.com/profile/00846754363995738243noreply@blogger.comtag:blogger.com,1999:blog-407728728590426370.post-8451425212203273442015-01-13T13:58:54.043-08:002015-01-13T13:58:54.043-08:00Hi,

In the case of AC power drops or fluctuations the PWM controller compensate that because has a wide input range from 2,5 to 16V. On the MOSFET the current goes up if the input voltage goes down. An improper or low transformer voltage (below 9V AC for example 5V AC) will trigger the damage on MOSFET because the switching current starts to increase to compensate the voltage drop on the AC input. The PWM controller due its simplicity has not protection for that meaning that the root cause problem resides on the use of a weak MOSFET. At the same time 90% of power consumption hangs on 5V rail output worsening the problem.

The chip integrates an interpolation sampling processor, DSP effects processor stage and DRAM-ROM memory controller for samples. On normal use overheats to much which degrades its logic, so a passive cooler is strongly recommended to cool it down. I do that for safety because logical failures on TGL-96 chip is one of the reasons about distorted sound, Regards.Anonymoushttps://www.blogger.com/profile/00733262184308744762noreply@blogger.comtag:blogger.com,1999:blog-407728728590426370.post-60251887030483547512014-12-01T04:17:35.974-08:002014-12-01T04:17:35.974-08:00Hi Chris, thanks very much for the information I w...Hi Chris, thanks very much for the information I will do the changes on my Korg TR 88. I figured out the weak design on the schematics and possibilities of damages due MOSFET short circuit on 5V rail output. After reading your post with pics I will replace factory P channel MOSFET with a T-220 case type to avoid further damages.
