Search ResultsI have a Panasonic DVD REcorder Model No. DMR-ES30V itwill not find any channels
Assuming the antenna is connected, and you still receive analogue broadcasts in your area, this machine should 'find' channels fine. Because this combo does not feature a DVB supported SD digital tuner (unlike the DMR-EZ series which does), it is possible that the analogue tuner (or its associated circuit) is faulty (the best way to determine whether your combo has a problem or if you have no analogue channels in it is to check your TV - if that still has analogue channels, and those are OK, then it is the combo's tuner which is the problem).
The problem with this circuit is the abundance of surface-mounted components on the copper side of the board as well as standard ones on the other side (particularly in the power supply as well as the tuner). When these tiny parts fail, it is almost impossible to replace these individually, as they are glued and soldered to the tracks; manufacturers nowadays lean toward complete board/chassis/module replacement rather than indivdidual parts. It is also time-consuming for a workshop to trace the sources of the fault within these components; so the labour cost increases accordingly, and the parts are not cheap, hence the board replacement scenario.
My guess is one or more surface-mount ICs and/or surface-mount transistors to the IF/RF tuning module has developed an internal short which will mean a workshop repair.
This may not be economical for a DVD/VCR combo with no digital tuner as the unit is over 5 years old.
Here's what I recommend: with the advent of digital broadcasts, the cheaper option is to buy a digital set-top box (SD or HD or both if you can get it - any brand with standard AV/RCA sockets) - connect the outputs of the box to the inputs of the combo (assuming there is no macrovision by the channels from the STB allowing some taping/recording occasionally), select the input 'function' on the DMR-ES30V ('INPUT SELECT' is not a channel and does not use the tuner; it uses a separate control circuit as part of the video IF stage), and this should be OK. You can try this, and avoid the workshop completely this time.
It's messy, but a lot cheaper and simpler, since your DVD and VCR part appear to be OK. You should not need to replace the combo at this stage. Analogue broadcasts are gradually being phased out. I hope this helps a tiny bit.
