Re: my jensen lcd tv

It sounds like you need to reset this device to original specs. This can be done by leaving it unplugger for 4 - 5 hours. Then is this does not work you will have to contact the company and get aa schematic. At that point we can begin troubleshooting.

TV comes on and then immediately goes off

It is called shutdown--set detects something wrong etc:

I see so many here with no sound/no picture issues:


1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signs of damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down the problem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the generic ones like Radio Shack). Many fuses are special even aside from amperage--Don't put a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses a standby power supply that runs 7/24 and a main supply (some are combined and some not.

Here aside from checking fuses you want to examine all the filter caps on the power/standby to see if any are puffed up or buldged up in some fashion--I attach a photo of a good one---top should be silver metal and PERFECTLY flat and have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating (saves money) which causes them to fail in a year or two---the standby runs 7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buy and try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over. If set is opened at least look for puffed up and bad caps like in this photo. 11_1_2012_12_27_00_am.jpg If its a 12 volt set using its own power supply that may be bad but you should be able to try it either with a seperate supply or direct to 12 volts.

Jensen VR187 radio/backup camera observation monitor won't work

In the manual look on page 10 step 10. You have to use a ball point pen and straightened paper clip (better) to reset the unit. There is a small hole at the lower left of the Volume knob. That's where you insert the paper clip.

Jensen LCD JE1907DC keeps looping the Jensen intro logo.

I don't have a solution but do have the same problem.
I took it in a reputable shop and they told me the main board was gone and they could not get parts for it.
I just found out that Jensen is a Audiovox trademark.

Axion handheld tv. No picture at all.

I have on and if the batteries start getting weak the screen display brightness is the first to stop working. Double check that, if you are on AC power try sliding the brightness control from dim to bright a few times and see if the rheostat has corroded. Those are a few of the quick checks you can try, let me know. Jay
