Hi fssidhom,

This is an indication of out-of-regulation in the power supply section, that's why you encountered the start-up problem. The very common caused of this fault is the leaky electrolytic capacitor in that section. It will drop the supply from normal voltage and will disable the unit.It needs a little warm-up to make itself stable but the symptom will get worst. Sometimes it has a bulged/dome at the top but not all, it is better that you have a capacitor checker/tester to determine its condition. Your unit will back to normal again if the leaky capacitor is isolated.

If you don't have necessary tools and test instruments, and can't do the job yourself, I would advice you to look for a professional to troubleshoot the problem. Don't attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored electricity enough to hurt you with a little mistake only.

Also check if your unit is under warranty /extended warranty, avail it because the manufacturer of your unit will fix it for free. Don't open the back panel, this will void the warranty.

Hope I helped you.

Have a nice day!

Thanks for using Fixya.

Hello,

It's the problem of overheating in the power supply board of the TV.on the power supply board of the TV there are few capacitors and IC.any of this IC is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.

Hope this will help in solving the problem.......

When I turn on the TV the green start up light blinks green and the TV comes on with picture and sound for about 2 seconds, then turns itself off and the code light blinks 4 times, pauses then blinks 4...


4 times blinking means Fan stopped, power is not supplied on Fan 1, Fan 2 Fan 3 and at Fan 4. Or Fan connector is not attached securely. Cleaning these fans by using a vacuum cleaner can also solve your problem. Sometimes these fans are clogged by dust.

if all you want to do is disable the vcr portion turn the set on , install a blank vhs tape it has to be blank or the vcr will try to read it .and the tv and dvd should work fine. this is a timing problem in the vcr deck its not hard to fix but it is a pain.
