Question about Toshiba TZ61V61 61" Rear Projection Television

1 Answer

TV cuts off, red light blinks. Unplug the tv and it re-sets itself. Happens all the time now. Which IC chip do I need to replace? Where can. I download schematics for this model showing how to replace the IC chip?

This is probably NOT a chip. Put the model number in a search engine with the words "power supply"

SOURCE: TV on/off light keeps blinking red light/no sound or picture on screen

Here's a solution that I received from an TV expert in another website: "This sounds like a power supply problem. i have seen it several time on your model. i would not keep trying to turn it on it might damage something else in the tv. the reason it is shutting off is because the power supply is putting out too much voltage. a repair cost will range around 300-400. this is a great model and well worth a repair. here is a web site that might help you in finding a repairman.
http://www.nesda.com/locator/state_search.php." <-- $300-$400 is too much! But throwing away a 300lbs TV will cost a lot of $$$ for the towing and dumping too. I haven't decide what to do yet.

SOURCE: TV turns off and power light blinks unpluged andd still does it.

Likely to be the STK convergence chips causing a protection circuit to switch the TV off. Have you got any onscreen convergence problems (i.e, colour fringes)?

SOURCE: i will be watching tv and it will cut off by

Have you replaced the lamp before? if not i might be going out, but if you have, there's a possibility that the ballast is sending irregular voltage to the lamp, which causes it to got out :)

SOURCE: Convergence issue, replaced convergence chips, now blinking red power light and no picture

Recheck all of your solder connections for bridging and cold solder joints. Check the large output resistors under the heat sink and the smaller ones to the left of them. Check all of the fuses on the power board. And make sure that you check all of your connectors carefully. Also check that you didn't pinch a wire somewhere.
I am not being mean by saying that if you could power up before then more than likely the power up issue was caused by something you did.

Heard a pop , bulb blew out , replaced bulb , it worked for two days , now red light blinks three times pauses then three times and so on , tv won't turn off light won't turn off unless I unplug...


3 blinks indicates lamp door is not on or has not been reinstalled properly. This also could mean the lamp door switch has failed itself. Try removing the lamp door and putting back on, if that doesnt correct the problem then I recommend having the switch replaced.

On power up I hold the power button down, I can hear some sort of relay kick-on, sometimes a horizontal white line appears across the screen, then it kicks-off, and the red led blinks four times...


Hi,
White line across the screen indicates that tv got vertical deflection failure problem that may be due to vertical output chip failure. If that kind of problem occurred, tv select protection mode and red light starts blinking 4 times.
Please check vertical output chip in tv main board and replace it to solve tv issue. This job needs soldering work so local tv repair shop will help you.
Thanks.

The tv will come on for a split second then click and cut off its a mitsubusi projection ws-55809


MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:


UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR 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 protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.


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


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

Toshiba projection tv with lines on screen


I have seen a lot of sets where the problem only happens when the set is first turned on---99% of the time one of the two STK-392-110 CONVERGENCE chips this set uses is Flakey--intermittant---The only way to know is replace both of the convergence IC's and see what you have---a bad IC can cause the set to shut down---and sooner or later the set will just shut down and not come on at all.

Let me know if you need more information about this type of repair as I have done hundreds of sets with this type of problem----every one I have ever seen where the convergence was intermittent----replacing the two IC's cured the problem.

42" panasonic viesta plasma tv cuts off after about 30 minutes


Hello gws51,

This sounds like a shutdown circuit proble, which is caused by the draw of excessive current. I would suggest that you have a qualified TV repair person look at you set and repair it.

I hope this helps

Thank you,

Toshiba TP55H60 power down after start up


Try the following
1-unplug tv
2-remove bottom cover on tv
3-tap the power supply frame a few times (where the power cord enters the tv)
I had the blinking red light on my tv. I tried other solutions like removing the red wire a few times etc. Tapping the power supply frame solve the problem.
