Question about Panasonic WV-CM1020 Television

1 Answer

Unit is dead....

This unit suddenly stopped working. It will do nothing. I have checked the fuse and the switch and both are good. I have now started checking individual components with a meter. However if someone has a quick tip, something to check or a schematic, it would be greatly appreciated.

    Thanks for the info. A large ceramic wire wound resistor on the AC side was open / not showing any resistance. I replaced the part and that took care of the problem.

The power supply is the first place to start.

Is there a transformer? Check to see that there is AC on the primary & secondary of the transformer.

If no AC on the secondary, then the transformer is bad. If AC ok on the secondary, then look for a bad rectifier diode/module and/or regulator module. There might also be fuses on the DC side of the power supply.

If the unit is completely dead, it's most likely a power supply issue.

Please let me know if I can be of further assistance to you.

Good luck!

26" 720p HDTV/DVD COMBO will not eject disk

First you do is to unplug the cord of your DVD unit for 5 hours in order to drain the stored current,the purpose is to reset the unit. After the 5 hours plug the DVD see to it if it open If not,just try to press down on the stop button and pressing eject button at same time and it will unlock the tray .Then the other option is to open the cover of the DVD unit and unplug the unit again to avoid electricshock . When open already look for the disc platter moved it outward while driving the gear or simply push out. The drawer or door of the DVD player and you will see a small circular disc which is often called turntable or disc platter.When the disc platter is out push it back and push it out you do this three times so the slider mechanism align it properly.If you do already what i said then plug it again and if works already closed the cover. The slider mechanism, depending on the age of the unit and the manufacturer, consists of the small chrome rail, a drive motor, a small gear assembly, and (in some units) a small belt that drives the slider unit via the motor. This small belt causes all sorts of problems. If the belt is broken or slipping, it can cause skipping, dropouts, or simply no start up at all. Also, if the belt breaks in the middle of the disc, the drive mechanism gets hair or dirt wrapped up into the gears, or the pick-up assembly doesn’t return to the start position (called home), the unit will (99% of the time) refuse to release the disc, causing it to become stuck inside the unit. There’s a little micro or leaf type switch located at home position that sometimes gets dirty or breaks and, causing this problem also.

Hope it may help you;

No sound gpx klc8806dt

Hello, i have fixed a few of these units, Mainly the problem is, is the crappy design inside, take out all of the screws from the bottom of the unit, be careful when pulling the top cover off cause the battery unit on the side is detachable and could be stuck and u can rip the wires off the system board. now you will see the 2 speakers, take a razor blade and carefully cut away the glue that holds the speakers in, and there may be little white plates with 2 screws that hold the speaker down also. Now take the speakers out and test them on a home entertainment center or a cd player that has red and black connectors for speakers in the back. See if they work first, if they do carefully reconnect the speakers to the motherboard and reseat the connectors back in with ease. try the unit again. if it doesnt work check the solder joints where the connectors attach to the motherboard, sometimes they will come loose. From my expierence with these units is they tend to jam the speakers inside so tight that they eventually stop working, so be sure to only use the connectors to hold them in.

Concept flip down monitor # cm 1520

Yes there is a fuse inside the unit,just open your unit and locate the fuse.If you aready change the fuse still not working then the problem go deeper.First, locate the horizontal output transistor. This is found very close to, or next to, the horizontal output transformer (also known as the flyback). The flyback should be on an aluminum heat sink, or on the side of the metal chassis. Disconnect or unsolder two of the three legs of the transistor. Measure it with your meter, or plug in the set with the light bulb attached across the fuse.
If the transistor is shorted, or the light bulb doesn’t glow bright anymore, replace the transistor and plug back in. If the light bulb glows bright again, you must replace both the flyback and horizontal output transistor simultaneously. In some cases this will fix the set, but sometimes there are multiple problems with a set.
Go to where the flyback is, and start measuring the diodes and capacitors on the flyback itself. If you don't find any shorts there, it could be a shorted vertical output IC, a shorted sound IC, a shorted disc capacitor in the Hi Voltage/sweep circuit, or in rare cases, a shorted capacitor or tuner. This TV monitor is small enough to take to a repair shop find a good one.You probably have to pay $50 - $75 dollars up..Feel free to ask and post whatever the result of your troubleshooting..

Hope this may help;

No picture or sound on tv

This sounds like a power supply problem. Check for a blown fuse in the unit. If there is no blown fuse then the power supply might have a shorted or open component in it. Check for the blown fuse first if the fuse is not blown or it can not be fixed by changing the fuse then the next culprit is the power supply, you will have to have a qualified TV technician do this.

I hope this helps
Thank you

Power Source

Are you certain the polarity of the connections to the TV are correct? If you connected them in reverse you may have damaged the TV. If there's a fuse in line check that too. BMW
