Green blinking "cst in" light/button

Its a color convergence problem from description:

If green light comes on for a few seconds and goes off:

On the front of the set (not the remote) press and hold both the menu and input (device) buttons at the same time for at least 5 seconds and release both.

Watch power light: it will blink a two digit error code, in your case I suspect it will be 2 blinks, 2 blinks and repeat several times.

Let me know error code and I will help.

MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ONFOR A MOMENT AND GOES OFF.

PRESS AND HOLD "device" and "menu"buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and twoblinks--this is the most common and easiest to fix. SD TECH

I had the same problem. We watched a DVD, and the unit worked fine. We went out for ice cream, came back, and decided to watch a VHS. Instead of taking the VHS, the CST.IN light flashed and the unit cut off after a few seconds. We didn't have a VHS in the unit at the time. After cutting the unit back on several times without success, I looked online for solutions. One person said to hit 'eject' 5 times in a row, but that didn't work for my unit. Someone else said there was a lever inside near the power button that ejected the VHS, so I checked that out next. I washed and dryed my hands well, and used my finger to jiggle the white lever. Then I saw that the tray that the VHS sits on wasn't all the way forward, so I gently pulled and pushed it. I'm not sure which of the two actions worked, but my light is now a steady green and my unit is working fine now. I am so glad because we've had this unit for almost 10 years now, and I really didn't want to have to buy a new one! Good luck!

power light if it shuts down should blink a error code--count the blinks and a pause?

Configuring codes:

1. Turn on the component that you want to set up. In the code listing find the 4-digit code numbers for your component brand.
   
2. Hold the component key down until the green indicator light comes on. The green light should come on after approximately 3 seconds.
   
3. Release the component key.
   
4. If you are programming the DVD or CD device press the "action" key. The red indicator light will come on.
   
5. Within thirty seconds, enter in a 4-digit code number. The component key lights will blink with an upward motion when a code has been successfully entered. In this case proceed to step #5. If the code has not been successfully entered, the componment lights will not blink. In this case return to strep #1 and start over.
   
6. Test code by pressing "Power" key. If the component turns off, you've got the right code. Follow the same instructions to set up your other components. If the component doesn't turn off, return to step 2 and use the next 4-digit code listed. Note: If none of the codes turn your component off, try the Auto Code Scan function.
   

Auto Code Scan:

The Auto Code Scan feature allows you to set up your components without having to enter in code numbers. The Jensen will do the work for you! (It may take a few minutes to find your code using this method.)

1. Turn on the component that you want to set up.
   
2. Hold the component key down until the light comes on. The green light should come on after approximately 3 seconds.
   
3. Release the component key.
   
4. If you are programming the DVD or CD device press the "action" key. The red indicator light will come on.
   
5. Press "0" - "9" The green light will blink as codes are sent.
   
6. As soon as the remote turns your component off, press the "action" key. (You have 1 second in which to press the "action" key to save the code.) The component key lights will blink with an upward motion when a code has been successfully entered. The component is now programmed. To find that code, proceed to Code Readback.
   
7. If none of the codes turn your component off, return to step 2 and start over.

Code Readback:

1. Hold the component key down until the green indicator light comes on. The green light should come on after approximately 3 seconds.
   
2. Release the component key.
   
3. If you are programming the DVD or CD device press the "action" key. The red indicator light will come on.
   
4. Press the "enter" key.
   
5. Count the number of times the green light blinks. There will be four numbers, separated by a two second pause. The red light will tum off after the remote is finished reading numbers back. Make sure you write the code number below for future use!

Multi-Component Power On/Off:

The Jensen remote has the ability to turn On/Off multiple components at once. When you perform the following steps, you can turn On/Off the TV, VCR, Satellite, Cable Box and Audio Receiver.

1. Press the "action" key.
   
2. Press the "power" key. Note: This feature does not work for DVD and CD.
   

Volume Priority Punch-Through:

When you press the volume keys on the remote they will control the volume on your TV. If you have a home theater system and want the volume keys to control your receiver only, you may set your volume priority to the receiver.
1. Hold the "RCVR" key down until the green indicator light comes on. The green light should come on after about 3 seconds.
   
2. Press "RCVR" key.
   
3. Press "Vol+" key. To disable the volume priority you have to set and return to the default.
   

To change back to TV priority:

1. Hold the "RCVR" key down until the green indicator light comes on. The green light should come on after about 3 seconds.
2. Press "RCVR" key.
3. Press "Vol-" key. The volume priority will now default to the TV volume.

hope this helps

try checking the cables first.

I had the same problem. Aren't three-year-olds great? Mine had jammed several clothing tags into the VCR slot. Clearing them out didn't solve the problem, but I then took the outer case off (with power disconnected of course) and verified that there was no physical damage to the tape heads and that everything internally was clear. I put the case back on, and everything's back to normal.

There could be several factors. Are there any indication or failure lights/codes prior to the unit shutting down? You didn't mention where the unit is located. Does it initially start to read the disc then shut down or is there no activity at all? Please respond with some additional info & we'll go from there.

Put a tape in and eject it. It will then work. Just had this problem. CST IN means the VCR thinks it has a tape in. Trust me... Very fixable.
