If you changed the regulator and it still doesn't put out B+ you must have an open circuit somewhere. That model is known to have a 6.3 amp B+ fuse that opens and you must check it with an ohmmeter to tell if it's bad. replace it with a 7 amp fuse and you should be ok. If that doesn't solve it you may consider taking it to a shop. By the way, you're welcome for the tip. Two out of a hundred people said thanks for my time. Russmann

Rca led50b45rq will not power up or come on


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Hello i need schematic diagram for power supply Model MEGMEET - ML686 . that power supply used for LCD TV .it's bad Brand and nobody care in service center. hope somebody help

Check the present power supply [SMPS]; and find out the number of switching regulator IC used. Surf the site with that IC number. You will get similar circuit for SMPS there.

Why does my Bush BLCD37 HDA8 keep turning itself off and the on again. It seems to only happen at home. I have sent it to a TV repair man who could not get the telly to replicate the problem, so he...


Check its main power supply regulator's output voltages. If main supply output from it is more than normal, this kind of fault can occur. [Over-voltage / Under-voltage] problem. The main system control IC in the TV will detect this condition, and will shut the TV Off. The best practice is to replace all the electrolytic capacitors at the main power supply regulator board.

Blinking light: 2 short, one long, top third of the monitor is dimmer


Check the power supply, but more likely to be bad VR3 Voltage regulator IC.
The root cause of the problem is due to bad 3.3V Voltage regulator VR3 on the main board, it is putting out more than 3.3v which caused the mointor sensing circuits which is use to find out if the correct power supply is being used with monitor to malfunction. If you do not change the regulator, it will cause more damage since the voltage will be too high. Taping off the pin is a band aid fix but more damage will occur.

Have Ge model 52GW945 tv, it went blank no picture, nothing, I checked fuse its ok what next


Check the swithed mode power supply section. Some sets uses Ics for control the power regulation, while others uses transistors as oscillators and choppers. If the power to the oscillator section of the SMPS is absent, the supply system won't wake up. So many reasons are there. You just check the resistor, usually connected from main DC rectified supply, to energise the oscillator section of the SMPS. In most sets it may be two resistors in serial, usually 270k 1W*2. If any one of this get opened, the power supply will not start up. Check it first and preceed. If the set uses Ic as regulator controller, check the positive supply voltage at the respective pin of the Ic.

MAKE IT THIS WAY FRIEND, IF YOUR POWER INPUT IS OK, AND THE OUTPUT IS FINE, THEN GO FORWARD FOR THE NEXT STEP, IF YOUR LA4558, (2CHANNEL AUDIO OUTPUT IC) IS HEATING UP, THEN JUST CHANGE THE IC, ALSO CHECK FOR CAPACITORS, ANY SIGNAL DIODES IF HAD DAMAGED, AND RESISTORS NEARBY...CHANGE THE AUDIO AMP

I plug in my casio ctk-800 and it does not turn on when i press the on button


If you lucky, the power jack may be at fault since it switches from external to internal battery, but most likely the internal supply is what's damaged... IC regulator possibly. A quick voltage check with a volt meter at the power leads on the main board will verify battery or xfmr supply voltage, if voltage is present then look in close proximity for an IC regulator and check for an output.

F61 problem


DIsconnect sound Amplifier ic (RSN).After removal of the ic if the unit works o.k offcourse without sound than replace ic.If still f61 than sound ic is o.k and check voltege regulators in power supply.You can check dc detect line if it gets activated.
F61 is mainly two resons 1st sound ic or power supply problem in power bord which send signal to system control to shut down the power in order not to damege more.
