I had the same problem! My fix was replacing both fuses and both 6800uf 16volt
capacitors. You can get the fuses at radio shack and I found the caps on ebay
in canada.

SOURCE: RCA HD52W59 Convergence issues after some repairs.

Hello rmolen,

This is an indication that the convergence amps are drawing too much current which has an effect on the power supply and thus killing your sound by removing or lowering the voltage supplied to that stage, finally this results in the blowing of the fuse. I would suggest that you change the convergence amplifiers and the biasing resistors (All of them) and then see if this corrects your problem (I believe it will). Also get a schematic of the TV and try to find out how the power supply relates the sound module and the convergence module, they might share a common power bus, or the voltage regulator for the sound also feeds the convergence board.

I hope this helps,

Thank you,

SOURCE: System won't power up

Hi,

Based on your description, we can limit the fault to the power supply board and in particular to possibly 3~4 components:

  • bridge diode;
  • filter capacitor (mains);
  • regulator;
  • filter capacitor (secondary).
blown fuse indicate a short in any of these.

As Jaime867 has suggested, in the absence of a readily available replacement board, component level might be the best alternative at the moment. Having posted the most likely culprits further narrows down your troubleshooting. Could you pls post back the part number of the smaller IC either 4 or 8 pins?

Alternately, pls check for the presence of a VDR, it would look like a coin (often green in color or something else) with 2 pins. They have been known to short out also and cause fuse to blow. One possible indicator is chipped or flaked of one side or a hairline crack on top. If it is chip, there would be a silvery color on the inside.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Rca led52b55r120q wont turn on. the red light comes on when plugged in but when power button is pressed red light turn off and tv does not turn on.


Sounds like 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://electro-medical.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.

Yamaha RX V671 will not turn on anymore after a power outage


The protection mode has activated.
Reset the protection mode as follows and see what happens.

Connect power cord to mains and wait 5 seconds or so. While holding down "info" and "tone control" buttons, press "main zone" power button briefly and release, but keep "info" and "tone control" buttons pressed for at least 3 more seconds. The unit should power up. Assuming the reason for the protection has passed or been fixed, the unit can now be turned off and then back on with the "main zone" power button to restore normal operation mode.
If the protector activates again, the fault is still present and the unit needs to be repaired, ideally by a Yamaha authorised repairer.
There are dangerous voltages present in high power amps and a lot of grunt in terms of stored energy - best left to trained technicians.

Vm9424 unit will not power on pressed reset button and it beeps and lights around function buttons come on and go back off fan comes on for about 10 seconds and turns off checked power ground fuses.is...


Hello lumberjack623,
When the jensen starts acting this way, it is simply a power problem. The device is not receiving power from the main source. The battery is weak and need to be charged before the unit can turn on once again. The battery power is too low to turn the unit on.
Try to check the power source or the connection to the power source. It is not charging the players battery. You need to have the connection port replaced. Also the power connection needs be checked.
The battery is simply weak that is why it goes right off when it comes on.
Hope this was helpful to you. All the best Elect_Comp

You have an overload somewhere which is causing the fuse to blow. They are mainly caused by shorted semicondutors (acting like a piece of wire instead of their job). Look careful around you might see damage or burnt parts.

RCA 61 INCH REAR PROJECTION MODEL # P61929 PUSH


The first place to start is the outlet and check to be sure it has power. The next is to check / replace the main internal (to the tv) fuse - it's a 5A 250V GMA fuse (google image of GMA fuse). To find the fuse, unplug the set and remove the back cover of the TV - follow the power cord to where it enters - the fuse is located to the right and slightly ahead of where the power cord is attached to the board.

Not accepting a disk, acts like there is another disk in there


Hold the "Eject" button for ten seconds and try it. Oh and if you have a 40 gb model (2 USB ports) and the Eject button dosent work then try this, Turn off the back of the PS3 (Main power switch) and then hold the eject button (while the main power is off) keep your finger pressed on the eject button flick on the main power switch and it should sound like some HUGE fan don't get scared, wait until the fan stops turn off your ps3, start it up and insert the disk and IT SHOULD WORK

Try it without a code. Turn your tv off. Press tv then press the on.off button and tv button at the same time. When it lights up, press play every five seconds until the tv powers off. Next press the reverse button every few seconds (sometimes takes a while), until it powers back on. When it powers back on hit the stop button to save the code.
