hi Jestine, greetings from s. florida,usa. did you know that there are thousands of hot tub spas in america and i guess europe. i have searched the web for weeks and could not find any info on repairing spas(hot tubs). there are no schools, there are no on line web sites, no manufacturer info what so ever. in fact the manufaturer's refuse to provide any servicing info ie schematics, parts list, etc. it would seem to me that this would be a very good opportunity for a person such as yourself to provide servicing info and techniques for troubleshooting hot tubs. regards pete guglielmo.

Hi ,jestine.

I sent a comment sometime in the first week of November regarding a
problem with my old Akai amplifier which uses two STK4026 hybrid amplifier ics for left and right outputs. One STK 4026 overheated and produced smoke. The power supply capacitors were alright and the power supply output was also ok.
I couldn't figure out what was the problem as both channels were dead.
I am still waiting for your help.

Munawar with the plethora of information available in the posts found on this blog and articles you can read as an ERG member there is no reason you will not be able to do the some basic repairs on LCD monitors and LCD TVs or other electronics equipment. After just one repair you should have made enough money to purchase the LCD Monitor Repair ebook and learn the advanced techniques of LCD Monitor repair and it would truly be a great investment.
