SOURCE: demo mode wont shut off

some friends of ours has this problem also. I've been trying to find a solution over the internet for a few hours now. I came across one page that said to hold the menu button on the front of the tv in for 20 seconds and that should fix it. guess we'll see.

You either have a cold solder joint in your horizontal deflection circuits or your or in your horizontal output circuit. please be careful due to the fly-back transformer still holds power even unplugged until you discharge it.( ground it out). Hope this helps.

The electrolitic capacitors are trickery: sometimes they look like fine but its capacitance has gone. The actual test is to replace them if you have not a capacitance meter to test them. Another approach is to check the Dual Schottky diode for leakage. It looks like insulated transistor and is screwed on a heatsink.

Sony KV32XBR400 Video Won't Turn

1. Try this - hold the menu button down for 10 seconds. TV should power up; you will have to turn off front panel buttons on menu.

2. You can also try a hard reset: Unplug TV from AC mains and remove all cables from TV. Wait about 30 minutes and replug to AC power and redo the cabling. Switch on the TV and see if it works..

My matsui tv 28WNO5(A) will not turn on from standby

Try pressing the small reset button on the back, it works, and you will not loose any stored information which caused the unit to go in the stand by mode.

Have you tried turning it off for an hour and then turning it back on. This happens to me quite often and leaving it off for a while ususally allows it to come back on. Also have you tried to press the TV/AV button on the remote as sometimes it switches to TV mode when its on standby and then standby won't work as its on TV mode and needs to go back on to AV mode. Basically just press the AV button on the digibox remote and then try standby.

if the batteries are removed and left for about 20 minutes before being replaced again, everything works as it should.
if any of the above suggestions does not work then you have to open the unit and on the main board of the tv there is a thin mini tube light like component called fuse you will have to replace that fuse .the fuse is very very cheap and you can easily get it at any electronics shop.and if still the unit does not work then there is a major fault in the power supply board and should be taken to the service center for diagnosing the fault that it is repairable or not.but i hope the above information provided will definately help you to solve your problem.

Tv tcl-14175 no sound on channels but ok on audio video mode


The first problem was always standby mode.... get back the original eprom IC 24CO8WP in to the PCB, then find the original remote control of you TCL Tv tcl-14175 then you power On In the Remote control while your TV is in Standby mode! then you see your tv is going ON... Because your unit is in Child lock Mode....

TV turns on at odd hours by itself

Hi, I had the "Ghost In The Machine". I tried out what I descibed in my original posting.
#1. I unplugged The Set.
#2. I pushed in and held in the power button in for about 5 minutes before bedtime. ( The PC trick I learned) I gave it 5 minutes because a tv set has much more power inside it.
#3. I again pushed in and held the power button in again for 3 minutes the next morning.
#4. I plugged the tv in again. The red standby light was lit. The set did not immeadiatly come on when I tried to power it up.
#5. 5 Minutes later I returned and hit the power button on the remote and it came on like nothing ever was wrong.
#6. It has been fine now for 3 days!!! Powers up when commanded and shuts down like normal. It has yet to come back on or act up as it was doing.
I will keep a watch on it and if it starts up acting again I will repost. I hope this information will be of use to anyone who experienced the same problem. It didn't cost a dime, just some patience. Thanks for a forum that people can exchange information and save trouble and money unless all options are exhausted. Bill

No Picture and Lttle red light next to power buttons blinks for about 30 seconds

First thing to do is reset ( see link below) and see if it resets otherwise if problem continues it will need some work

Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits. There are some common breakdowns in the High Voltage circuits in this set. One is the flyback transformer. Another is a small high voltage capacitor in the sweep corrction circuit. There is a cap that goes open in a high voltage circuit (C6532) which needs to be replaced.

Sony tv wont turn on, standby light just flashes

I had the same problem guys! This is what I did:

My T.V. wouldn't turn on. The standby light was flashing six times, then four, then seven...I called Sony and they told me to unplug it for a couple of minutes, then try it again...didn't work....BUT, I have found a solution:

Try unpluging your T.V. for 4 hours+, then turn it back on. Worked for me! It's called a "hard reset" by sony. I had my T.V. unplugged for the whole day though.

SHARP 29" TV switching off to Standby

have you tried changing the batteries just to elimate this problem

change them

sometimes if the batteries are low in electronic devies, they send a wek signal to its receiver (your tv),

your tv gets confused and then switches itself to standby

if you have changed the batteries and this problem still persists

it can only then be th PSU or power supply unit, take it to your local tv repair shop of mastercare somewhere like that, its going to be cheaper to get it repaired than replacing the whole tv

PSU'S generally 20 to 50 pounds depending on model

don't deo it yourself though unless you've got a capacitor discharger (or a nice 25KV will be on its way to your body)

hop this helps mate, let me know how you get on

No Picture, Sound Fine

Hey John, How many times does the light blink? No blinks - Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open). Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective. One blink - not used for the self-diagnosis Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits. Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672. Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505 Five blinks - AKB circuit (automatic kine bias), 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 Cboard, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly. Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206. Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits. Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some newer models of Sony TV sets, this code means that T8005 is defective on the D board. Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negitive). Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board. I suggest you do a hard reset. Unplug the power cord for 4 hours. Then plug it back in and check it. If it works, great. It not, cost of repair for this is usually around $150 - $250 plus the house call.
