Question about Samsung HCN4727W 47" Rear Projection Television

1 Answer

Power light comes on and blinks then tv shuts down.


I am currently having the same issue as another member (Pserrano) with the same model tv. I have copy and pasted his question below.

   "My television will not turn on.  If I plug it in, or press the power button the red led lights up 10 times.  Every other blink is slightly longer the the other.  Are you familiar with this problem?  Thanks you in advance for your help."

Thank you for your time.

Power in house was shut off today, when restored, the timer led light by the power switch has been blinking constantly and the power to the TV will not come on...

Thats a common issue for that model which is caused by weak DM capacitors. When the power is down the caps discharge then they cannot recharge when power is restored and the led blinks non stop. Thw WS48511 - WS65511 DM repair kit from has the caps and the repair instructions which usually solve that issue.

Monitor goes off and on by itself

Hello bjaykaye,

The problems you are having are an indication of a Power Supply problem. The issue could be in the switching power supply or the High Voltage Power Supply. The shutdown circuit is activating which is allowing the TV to play until it detects an over-current event. When an over-current event happens the shutdown circuit will turn the TV off. I would suggest that you check the Horizontal Output Transistor, the HV Transformer, the Horizontal damper diode, and the capacitors that are in parallel to the damper diode. The important thing is to find the component that is causing the problem. If you do not have a background in electronics I would suggest that you get a qualified electronics technician to look at the set.

Thank you,

Television keeps shuttting off and on green light appears

I have a Sony Grand Wega 55 HDTV, Its 6 years old. Problem is as follows: I press the power button and the TV warms up and goes on for about 30 seconds than shuts off to a no power screen , with the power light flashing green. Than after about 60 seconds the TV comes back on for about another 30 sec and shuts off again. The longer i leave the TV on the longer it stays off when it starts blinking the green light. Can anyone tell me if its the sensor or something else? Is the part I need attainable with the ability to replace it myself.
Look forward to your replies.

The TV shuts off then the power/standby light blinks continuous for about 20-30 times then TV turns back on.

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 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, but if otherwise Power supply board have problems,just not dead yet.Replaced the power supply board,will solved this problems.Tries websites like, to buy a refurbish power supply board for the replacement.

Mitzubishi projection tv power shut down and won't power back up. green light comes on for a second then it shuts down immeditately

MOST Mitsubishi sets have a self check feature:

When power light goes off: On the front of the set press and hold MENU and INPUT (device) BOTH FOR 5 SECONDS OR LONGER AND RELEASE.

POWER light should blink a two digit code: for example:
2 blinks, a pause and 2 blinks----it will repeat the error code several times.

2,2 is the most common and the least expensive to fix.

LET ME KNOW EXACT MODEL NUMBER and the blink code and I will tell you what it means and if 2,2 how to fix it.

Immediately Shuts off with blinking light codes

I suggest doing a google search using the tv model # and brand.
I have learned myself that different big screen tvs seem to each have their own common problems. I have read before of power supply issues that cause what your describing.

TV turns off after two minutes. Power light blinks for a few minutes then TV comes back on. Turning the power off after the set shuts itself off will cause the power light to blink five times for a minute...

5 blink indicates - AKB circuit (AKB), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. Also unit be in IK blanking, try turning up screen slightly.
