Why does picture flicker three times per second?

I'd look at a bad panel, the defective panel damaged your main, replacing that got it working somewhat but if it's on very long I'm guessing you will damage the main board you replaced. Try unhooking the ribbon connectors one at a time and see if half the picture works ok, if so you definately have a bad panel

Hey there,
Sorry but the Corby does not have an option to place three different pictures as your wallpaper, it only allows one picture.
A way around this would be to take three pictures that you want to use and combine it into one picture using your computer and then loading that onto your phone. This way it is one picture but it will look like three pictures on your phone
Hope this helps!!

There is a procedure in the owners manual on page 110.

BeltMinder activation and deactivation procedure
1. Turn the ignition switch to the RUN (or ON) position. (DO NOT START THE ENGINE.)
2. Wait until the safety belt warning light turns off. (Approximately 1–2 minutes.)
• Steps 3–5 must be completed within 60 seconds or the procedure will have to be repeated.
3. Buckle then unbuckle the safety belt three times, ending with the safety belt unbuckled. This can be done before or during BeltMinder warning activation.
4. Turn on the parklamps/headlamps, turn off the parklamps/headlamps.
5. Buckle then unbuckle the safety belt three times, ending with the safety belt unbuckled
• After step 5 the safety belt warning light will be turned on for three seconds.
6. Within seven seconds of the safety belt warning light turning off, buckle then unbuckle the safety belt.
• This will disable BeltMinder if it is currently enabled, or enable BeltMinder if it is currently disabled.
7. Confirmation of disabling BeltMinder is provided by the safety belt warning light flashing four times per second for three seconds.
8. Confirmation of enabling BeltMinder is provided by:
• The safety belt warning light flashing four times per second for three seconds.
• Followed by three seconds with the safety belt warning light off.
• Once again, the safety belt warning light will flash four times per second for three seconds.
9. After receiving confirmation, the deactivation/activation procedure is complete.

If you did not get an owners manual with your truck ( purchased used ), you can download one from Ford :

internal error. if the lamp looks ok and it doesn't have many hours on it, it might be the power supply. the capacitors dry out and do not supply sufficient voltage. the in72s do have that problem.

I'm afraid I don't have good news. This is known as the "Flicker Issue." As a Sony authorized servicer, the shop I worked for was directed to replace all three of the CRT's in the limited number of sets that experienced this issue. The cost per tube is typically around $200. If you decide to take this on, it is best to replace one CRT at a time, power up the set and do the yoke adjustments and electrical alignments to get the new color to line up with the existing ones.

try this simple test i know its kinda weird, but it helps to know what seems to be the problem.tap your unit three times, while tapping look at the screen, see if it flicker or the screen has picture.then, check all connection, if its all ok. then, you'll need a tech to do a manual troubleshooting.

Good Morning,

Your connection is very easy so we should not have a problem isolating the problem.
We just have to go slow step by step.

First lets just check the Yellow cable just to be on the safe to side sure it is connected properly on the back of the DVD player and on the Televison.

Second, If the connectionn is secured. Turn the DVD player on, make sure you do not have a disc in the tray then turn the DVD player off.

Make sure the battery on the remote control is a fresh new battery (process of eliminattion).
Hold the remote control in front of the DVD front panel.
Turn the DVD player on with the remote control. Look on the front panel of the DVD player, it should read no disc. Press the Pro.Scan button "once". (Have you notice a flickering on the Television Screen).

If no flickering on the TV screen, press the Pro.Scan button again, ( this will be the second time). Have you notice the flickering?

If not, press the Pro.Scan button again ( third time). Have you notice a flickering on the TV screen?

Did you not notice on the LED of the DVD player if it read anything when you pressed the Pro.Scan button?
Try the above procedure again if your picture did not resume. If the picture resume in black and white, do not press the Pro.Scan button anymore.

Let me know the outcome up to this point.

Thanks,
Mike H.

try to reset it to factory setting. First press ok then down arrow 7 time then ok one time next down one time then ok.
Hope this help you.

dear,

if you have checked it by changing the lamp then there you will see a thin peice of coloured plastic (colour wheel). Vacuum that plastic and all around it but dear plz dont touch that one.

regards,

This sounds like a line timebase failure. The line timebase works at about 15 thousand cycles per second (15KHz) which may be audible to some people due to the iron-ferrite materials used (magnetostrictive). The line output transformer is highly stressed and also has the rectifier diodes in the outside if the windings. It is all very well insulated to guard against moisture and dust but if it breaks down due to the high voltages (25Kv) the arc produced makes this squealing noise, and of course it burns out, and breaks down. This may not blow the fuse if there is not a short circuit. So get an engineer if you are not sure about changing the line output transformer.
