System unresponsive when modes are switched

I have a JVC Home theater system model #THA30 The disc tray does not open for playing cd's or dvd's. The radio works fine and the Aux function works ok also. I unplugged the unit for two hours and the disc tray would open but after turning the unit off or changing from dvd to radio it stops working again. Thanks in advance H.L. Allen

Re: System unresponsive when modes are switched

Arnt they seperate things? ive seen some systems that dont function if thery are not in that mode. If its in DVD mode nothing on the DVD works, if its in the radio mode maybe the power changes over to the tunner only? you cant play both at once maybe their idea. Will things work when its in the cd mode? Is the unit staying cool?

Re: System unresponsive when modes are switched

Sounds like there may be a glitch in the microprocesor. Make sure when you unplug it that you leave it along for a few days and is there any type of clock or standby batterys in it take them out as well. If that dosent correct the problem your gonna need a service manual to trace the switch pulse to see if the units Switch matrix lines are low or lost because of a faulty micro or a bad componet like a small caps they install on the matrix to keep noise off them. Hard one to call with out seeing unit and analizing unit Good Luck

How to convert the my jvc dvd player to ntsc to pal or vise versa, coz i used old tv so i need to change it . tnx my jvc model is xv-tha30 dvd cinema system

You have to use an external device to convert NTSC to PAL or vis versa. The device cost between 175 to 250 $. I think you can buy a small new generation multi system TV for that price !!!!.

My JVC TH-G30 gives me a locked message when I try to open the load tray what should I do?

hello Setting the disc ejection lock
You can lock the disc tray to prevent the disc form
being ejected.
When the main unit is turned off, hold down the STOP
key at the front panel for 5 seconds
If you attempt to open the disc tray by pressing
OPEN/CLOSE key, the disc tray does not open and
“LOCKED” appears in the display window.
To cancel the disc ejection lock, hold down the STOP
key at the front panel for 5 seconds again when the
main unit is turned off.
“UNLOCKED” is displayed in the display window.
Before the main unit is turned off, DVD/CD function
should be selected.

I am getting the locked display

Hi Blackhawk,
This sounds like you've accidentally set the "tray lock" feature.
You can set this to stop unwanted tray ejections:

I hope this solves your problem..
Warm Regards

Tempremental playing dvds

In response to your jvc-a75r DVD player, sometimes the solution might be less complex than it may appear. Had the same problem with my Samsung s321,the machine refused to read DVD's but would play CD's no problem. Simply opened up the cover(usually)4-6 small screws, and found my dog's hair inside of the player covering the laser eye.Electrostatic ionization attracts dust,etc. into the player remarkably well sometimes. Carefully used a cotton swap to remove debri. PLayerworked fine afterwards ...Good luck!
