    61H71 no picture no sound and power led is blinking, I have unplugged to reset for more that 24 hours and it fixed nothing. When plugged, it makes couple of clicks and issue continues. I did have some convergance issues before but never repaired it. So today I changed both IC's (stkSTK392-110)but the problem still continues. Any Suggestions appreciated.
    Thank you

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem on dvd with no receiver box connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic chargesaccumulating on capacitors, or because of a wrong voltage read by themain chip on your monitor controller board. this started the protectioncircuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Commonfaults that can occurr suddenly are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.
check also the video cable, if the cableis shorting, or the connector is bad, you can get same flashing statebecause of the video cable.

Check also connectors, try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

As you said before you had convergence problem before ,but you still continued using this further this may have damaged the other parts or most probably the main board of the tv.

check out this link

also if its main board replacement then going for new tv is worth getting.

Hi, the first suggestion would be to rebuild or replace the power board. the second would be to preform a break point test on all circuits. last, i would replace the convergence as well. the red light is signaling a power board failure. the clicks you are hearing are also from the power board. its malfunctioning.

A service / repair manual should have information on the blinks and explain why and what is wrong and what to replace.

    Did you replace resistors and capacitors along with the convergence IC s .

    Also did you replace one IC or did you replace both convergence IC ?

    If you replaced one it wont work . You need to replace both convergence ICs and also you need to replace capacitors and resistors along with it .
    You need service manual for this operation to check the bad capacitor and replace it .

    Hope this helps .

The Timer/Standby LED light is flashing on the front of the TV. Can turn on TV with sound but no picture, TV shuts off within 5 seconds.


Hi,

The Standby/Power light of the TV blinks when there is any internal malfunction in the TV. The self-diagnostic function of the TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue.
Few examples are given below; some of the issues may be resolved without the need for service.
1 blink / 2 blinks / 5 blinks: - This indicates that there may be a power-related problem with your set.
3 blinks: - This indicates that there may be a power-related problem with your set. The set will need to be serviced to allow a technician to determine the specific issue that needs to be repaired. If the power light flashes three times in sequence in a Lamp TV, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
4 blinks: - This indicates that there may be a back light or lamp power problem.
6 blinks: - This indicates that there is some kind of audio problem with your set.
7 blinks: - This indicates that there is a temperature problem with your set. Please check to make sure that the air vents on the sides and back of the set are not blocked or clogged and there is adequate ventilation around the television. We recommend that you check and clean the vents periodically to make sure the set receives adequate air flow. If the problem continues, the set will need to be serviced.
8 blinks: - This indicates that there may be a video-related problem with your set. If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.

If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
If the issue continues to occur, service may be required.

My 55313 mitsubishi just will not power on. green light comes on but then goes not off not ever producing a picture. ran error codes, none detected? what could be wrong? plz help


Hello.
Just in case if you have done it wrong.... To retrieve error code plug TV into wall outlet. Push power button, let it do whatever it does. After that push BOTH buttons in fron of TV named "Menu" and "Input" and hold it for at least 5-6 seconds.
Green LED in front of TV will start blinking error code (when it starts you can let buttons go).
If it clinks like "2 blinks, pause, 2blinks longer pause, repeat" most likely you have convergence issue. Two convergence amps have to be replaced along with couple PICO fuses that already open.
I would strongly recommend to let professional do this repair. As well in case of different error code.
Should cost you in ball park of $250-$300.
Regards.
Russ.

Toshiba model 61h71 red light comes on /no picture or sound


We had the same problem, open the panel on the back of the tv, the board on the left, not the one with the convergence chips. Inside the tv u will see a piece of paper with the fuse info. The board on the left unscrew it and flip it away from you, the fuses to test are at the bottom, on the circuit board it will say 125volt 5 amp, and the number starts with an f. they are small and rectangular and black. Check all but the 3 at the bottom are usually the culprits Hope this helps u

Our 61H71 just did the same thing! I have found on another site where a fuse on the Convergence board was replaced as a fix for this issue...however, fuses are usually symptoms not causes...it is very difficult to find availabe information on this issue...it may be time to call a professional...Good Luck!
