My JVC CA-HX-Z10 works just fine but the speakers tend to turn off. I unplug it for a couple of hrs and then plug it back in and it works just fine for a couple of minutes and then the sound just goes off....


This is a semiconductor or capacitor thermal problem. You will have to be able to get to the circuit boards. With a can of Electronic Cold Spray (freon), you turn the unit on until it heats up and the sound goes out. Then, try spraying transistors and components once at a time, until the sounds comes back on. This will be the bad part. You will have to unsolder it and take it to Radio Shack or electronic parts store, or possibly order one online (google the part number, or value on the capacitor, etc.). Problems like these are usually transistors, and they usually only cost a few dollars (maybe $25 at the most). Inspect solder joints to see if they're cracked, or discolored (indicating a "cold-solder" joint, which you can resolder with fresh solder applied. The hardest part of fixing this type of problem, is that you have to sometimes take it all apart to get at the back of the circuit board to unsolder the bad part. Take pictures as you take it apart- they will help you putting it back together. Good luck!

Rca hdtv 52inch will play fine then picture goes black but still has sound.. after a few mins.picture will come back on , and will play fine could last all day or may go out again in a few mins.


My tv is relatively new, but the bad thing is that I had an old; big screen tube type rca model; home theatre, that was heavier than a car, and it went out, due to the cracking and popping sound, off sometimes, and back on.
What is strange is the new tv now, the hdtv, light weight, about five years old, is doing the same thing. Actually, now, the power will not even come on. The lcd green light in the front goes on and off.
Take no offense, but I thought I would not have these problems anymore. What do you suggest?

My gas gauge works (not incredibly accurate, but works). When i stop for more than a few seconds the gauge goes to empty. when i start moving it goes back to full and slowly comes down to where the gas...


As far as the gas gauge level goes, it sounds to me like it could be the float ball system that is inside of the gas tank, which is connected to the fuel pump.I dont think your guage in the dash is broke, but i could be wrong. Sounds like something in the fuel pump area

I have garmin nuvi 300 satnav and it is not charging. i changed the charger, charger itself is working, the problem is with satnav. please help me out


Sounds like you might need a new rechargable battery fitting in your SATNAV if the battery is not holding charge with the cable fitted then this is you most likely problem.

This should be done by a reputable dealer as it is not recommended for users to do this as you can crack the screen when taking the back off.

2000 caravan 3.0 stall after 20 min no spark restarts few hours later


This sounds like a bad (probably cracked) ignition coil.

First, the coil gets hot when operating, and this is normal.

If it is cracked, it gets hot to the point where its resistance gets so much higher that it cannot provide enough voltage for spark.

When it cools back down it starts working fine again.

F20 power port connection broken in unit.


Hi,
I have recently acquired a Navman F20 Satnav with a broken USB port (It was rattling around inside the unit.)

I took apart the case and re-fitted the USB port with no problems at all. Just with a steady hand and a fine tipped soldering iron. I also superglued the port in place to add extra strength.

Put it all back together, and it now charges and connects to the PC exactly as it should.

So, before you throw away a sat nav with this problem, contact me and I can fix it for you, or, alternatively I will offer to buy the broken unit from you.

My Email address is darren.lee27@ntlworld.com.

Thanks

Sounds like a bad solder joint in the power supply or if your audio stays when you lose the video its probably in the deflection circuit either vertical or horizontal. Check the yoke connections.pins for cracked solder as well as the vertical and horizontal outputs also around the flyback.

NO SOUND


I had a similar problem with my Navman F20 (no sound through speakers but OK on headphones, through the T1 module). When I opened the back up, I found that the speaker connector had come loose from the PC board - it looks like it's a **** fit anyway.

Undo the two screws holding the case together and gently prise the two shells apart, I used a broad bladed kitchen knife. I found that the speaker plug had fallen out of the socket, popped it back in and Bob's ***********'s brother.
