Magnavox 32ME402V/F7 No power

[pop70458]

Hi, I have a Magnavox 32ME402V and the tv had a blown fuse. I replaced the fuse and the set has no power. The pfc has no voltage at all. The tv is made by funai.

Did the fuse go again? if not possibly open diodes in the bridge circuit?

The fuse is still good but I have no voltage on the primary cap.

Re: Magnavox 32ME402V/F7 No power

check those diodes one or more is likely open

Re: Magnavox 32ME402V/F7 No power

The ceramic resistor <Ph>5W1R2J was bad and I changed a few diodes also.

Does anyone know where i can find a replacement?



Part number listed on resistor is <Ph>5W1R2J

Digikey or mouser should have replacements. Digikey has cheaper shipping on small orders

I have the same set that is making a terrible buzzing noise when it is plugged in and won't turn off. The buzzing seems to be coming from the large transformer on the power supply board. It stops buzzing when I unplug the other board with all the video inputs on it. Does anyone know what I should test? Thanks in advance.

Not sure if this thread still open, but having the same problem finding part:
ceramic resistor <Ph>5W1R2J. Search on this number at Digikey and Mouser bring up nothing. What would they be listed as? Thanks

Hello all! I have same board but I cannot make out the part numbers on L601 and L602.

I think you will be better off with the new board, for the common mode chokes to burn up that bad, the load must be really shorted out. I can see the PCB by that power resistor is burnt into carbon which is conductive so that section of the board will have to be removed which will make the board useless.
Did someone install a really high current rating fuse in place of the original fuse?
This is really crappy TV with bad power supply design.

I'd respect BudM's response.
Maybe a different problem I had, but I was able to repair two of these TVs.
One I used shopJimmy's repair kit below:

The other had a burnt spot under the ceramic resistor, and I found the kit below on e-bay. Fixed my problem:

Good luck.

I used the same repair kit off eBay for same model TV about three months ago.
TV still working great.
