Sanyo ce28 wn7-b just failed to turn on one morning.no internal or external fuses have blown.

Replace adapter cable only, do not replace the power supply by your own ! tTake it to the nearest vendor representatives

There is an internal fuse if could be blown. If the fuse is good you might try reflowing the solder on the power board.

You can attempt to recover it by either filling up a tub of white rice and leaving it sit there for a few days to a week, or you can put it near a heater to try and evaporate any remaining liquid. These steps will only work if the spill is very recent. It is possible that an internal circuit has been shorted, or an internal fuse blown. If either of these have occurred you will need to have it serviced by a professional. Contact Sanyo to locate a nearby location.

You probably have blown capacitors on the PSB-power supply board. Recaping with new UF caps works 90% of the time. The set turns itself of into a fault protection to keep from damaging more components internally. A few bucks a soldering iron some solder should do the trick.

Probably the failure of a high-amperage fuse inside the unit. The electronics are generally separately fused so one section can fail leaving the other functioning.
If there is no external fuseholder on the back panel, it will be necessary to remove the housing to access the innards.
The fuse that has blown may have blown because of metal fatigue but the cause could also be more serious, namely the high voltage diode (or diode bridge) that converts high voltage AC into the DC required for the magnetron or even the magnetron itself may have developed an internal short.
If you locate the fuse, buy two of them and if the first replacement fails again, then the diode(s) or magnetron has failed and with the cost of service plus parts markup, you will be better off replacing the whole unit.

There may be an internal fuse, but the unit will need to be serviced by an electronics shop.

If no odor or burning smell happened, then I suspect a bad solder joint or cracked circuit board. Look the board over with a very bright light.

LOOK for a dark circle around pins of HEAVEY components in the solder menicus for all the pins of the heavy components.

Look for board cracks with a small LED flashlight shined through the board.

An internal fuse may have blown...

French TV works on a diffrent frequency to uk i cannot remember the details but one is PAL as memory serves me a modern tv should switch over in the settings
