Well done Mirko! And thanks for helping keep our planet GREEN rather than toss another failed Chinese manufactured piece of electronic equipment in a landfill junk heap! Restoring previously failed electronic equipment back to fully operational condition approaches being Godlike in my humble estimation!

@@mikeadams110 soon china will not sell anything to the usa anymore, don''t worry.

I effing well love your vids. You rock sir. You rock.

Electronics repairing except tools needs extra more human senses!

The problem with bad caps on power regulation is that failing cap may have caused too high voltage to the IC and destroyed those for good. A well designed board wouldn't do that but many boards are not well designed.

@@MikkoRantalainen please tell me what I C stands for I had one blown cap on a Jensen TV set and I fixed it put a new cap in and it's still no picture or sound so I'm just curious what else might be damaged for me to look at all the other caps look good but I haven't checked the with a estimate meter

@@johnmitchell8925 IC means integrated circuit. Basically the stuff that most people call "microchips". The problem with IC is that those really cannot handle overvoltage and many poorly designed power sources output too high voltage to one of the power rails going to IC which basically frieds the internal parts of the IC. The only way to fix the device is to replace all the affected ICs. If you don't have schematics for your device, figuring out which ICs are broken is going to be hard. All the chips are usually just okay visually because we're talking about 2 V instead of 1.3 V to CPU, 9 V instead of 3.3 V to memory and so on. Definitely not enough to cause charring but too much to cause just temporary failure to the chip.

Look up ESR meter on Amazon/eBay can get a cheap works great ESR meter for under $30.

On a fender deluxe reverb from the 70s.

That logic could apply to literally *any* component tho

12voltvids where can I find that meter?

Mike Lornitis Watch 6:10, he tells you exactly what the meter is. Google is your friend!

Here's what I read somewhere else and I think it's a good idea have some known good new capacitors that you can check and then check the ones you suspect and you'll know what the the the ERS should be reading on a known one good one compared to your one in the board

Technically, most "general purpose" caps are rated at 20% tolerance from their designated outer case marking relative to capacitance value. This means a brand new cap fresh out of the factory rated at 1000uF could actually measure anywhere between 800uF to 1200uF being quite a wild deviance from spec right off the bat! In most cases, they'll prove more reasonably closer to their preferred value rating considering today's modern plants exercise some degree of component quality control. Nonetheless, be sure not to exceed that inherent deviation any further from the component's original ideal rating, meaning 10% higher or lower in value from spec. Bear in mind, capacitors of any kind (electrolytic, ceramic, epoxy, trimmer, etc) serve one of 3 primary roles in electronic circuits as detailed below the next 2 paragraphs. Arbitrarily changing the preferred values from spec in any of those roles will absolutely cause a measurable negative impact upon the circuit's performance to some degree. Whether acceptable or not is entirely a gamble and wild guess at best. Taking that kind of unnecessary risk simply isn't worth blowing out a more expensive (perhaps harder or impossible to get overseas component) somewhere up or downstream within the circuit such as a specialized IC, microprocessor, dedicated microcontroller chip or Laser diode. 1. decoupling capacitor. Used in this role a cap will remove any DC component (meaning plus or minus DC bias) an AC signal may be riding on back down to ground (meaning zero as in baseline on the oscilloscope) rather than riding up at +5vdc for example. 2. filter capacitor. Used in this role a cap will filter-away (meaning dump to ground) any specific undesirable AC signals (meaning unwanted noise or potentially false triggering signals) such as leftover 30hz half-wave ripple in a DC power supply. This "cleans up" the DC purity and stability quite dramatically just prior to more precise IC regulation (using an LM7805, LM7812 or LM317 for example) being the final back-end stage in any quality power supply. 3. timing capacitor. Used in this role the cap sets a highly precise desired frequency in an RC (resistance/capacitance) network circuit. In this case and role the capacitor's value shouldn't be varied even the slightest from spec without causing drastic performance trouble or even device failure. Rather than arbitrarily deviate from the original circuit specs purchase a low-cost ($20) bulk assortment of the most commonly used electrolytic capacitors to keep on hand of which there are around a dozen. You're typically given 8-10 of each value in such assortments. Be sure to order the low-ESR variety if they're going to be used in any switching power supply unit (SPSU) all of which inherently demand and rely upon this special requirement. You'll find 99% of the time the caps which fail in a SPSU are nearly always the general purpose rather than low-ESR variety being why they suffered an early demise. That harmful concession nearly always having been made by the manufacturer being a tactic by which to minimize a product's cost. It's quite revolting and rather unjustifiable considering they're saving just pennies on the dollar at the expense of a product's overall life expectancy. So spend those few extra pennies to get quality replacement caps which meet specs. In which case, they'll last for decades rather than just a year or two after warranty expiration at best.

+roidroid Ya maybe for them, but for us got to take it apart and do not know exactly where hte tabs are or what the method is to "unsnap" them. Screws are self-evident.

indeed. Appliances aren't made for ease of servicing, they're made for cheap manufacture. AFAIK Labour is one of the major costs in the manufacture industries, so any savings they can get there pays off BIG. If a part can be redesigned to save a mere 1 second of labour time, they'll do it. They probably save so much on labour by using tabs, that it more than offsets the costs of just replacing all faulty appliances with new ones (instead of servicing them). So in the end it's the more profitable option to make non-serviceable but very-quick-to-assemble appliances.

yes you can hurt yourself

Yes. The internal switching power supply units are dog crap which will eventually self-destruct due to an inherently flawed design relative to the feedback loop. It can run away under certain adverse conditions and blow out any components in the path of least resistance which sink a sufficient level of current necessary to destroy themselves. Those, most typically being electrolytic filter caps.

Yeah and those classic CCFL backlight transformers are hot like hell. Last time I fixed monitor where transformer overheated and secondary wiring was burned, and by some time there was sparking that probably damaged CCFL tube and inverter IC was shutting down after 1 second, even when I repaired transformer and tube was lighting, to fix it I had to add 10pF/1kV capacitor in parallel with defective tube. But before I figured it out I spend few hours, IC based faults are bitch to troubleshoot, there was even no datasheet for that IC...
