If you still have the manual, look in it and see what it says the code of the blinking light says. It will usually give you an error code that we can work from there. This clarify the problem that needs to be fixed.

Hi

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.
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.

Please revert for any clarification.

Thanks

Its the problem of the internal ic that has gone faulty on the main board.but it has to be checked properly with multimeter as this ic with itself also blows 1 or more two components.so all of the above it has to be checked with a proper professional but if the whole main board needs replacing .then its not worth getting it fixed but if only the ic replacemt then its worth fixing the tv/.

I think that you may have a few problems here. If you can solder, we should be able to resolve them. First, resolder any connections that appear grainy or have rings. Once that is done, the symptoms should either go away or at least change. Please update this with the new symptoms and we'll continue from there.

Based upon the symptoms you've described, I think you have a problem with the vertical IC. Please try the resoldering first and update this.

Thanks,
Dan

Unplug the tv for a while and then plug back in and check initially before we check out other issues.

Even Sony is having some reliability problems with their video and tv products.

The continuous blink indication, as the link you pointed out indicates, is an IC problem. Probably the IC that contains the diagnostic routine in it; although I don't know that for sure.

The IC 301 mentioned in the link is what we call the Jungle chip; it is the main processing agency for the video, particularly the Y/C processing. It is a big, very complicated IC with over 50 pins. It could be the IC or something totally unrelated that the IC is merely monitoring. There are a host of functions manageed by the Jungle IC among which are automatic switching, buffering of video, S-video driver the R, G and B outputs - and one or more signals to the protection circuit....... if all that means anything to you.

So, what is the problem? It will require a deeper diagnostic investigation; preferrably by someone who can put hands on the set and do some testing and evalutating.

As a general rule, any time the blinking of the standby light occurs it is determined to be a major matter. Unless a simple hard reset cures it you can plan on it being a moderate to expensive repair.

The audible click is the relay switching power ON/OFF. The protection circuit is the controlling factor which tells the relay to turn the set off. It may be coming from the Jungle IC or somewhere else.

But the real question is whether to fix or replace. The set is getting along in years. As a rule of thumb, any set with a serious problem and is more than 3 or 4 years old is NOT a candidate for repair (unless it is known to be a trivial repair like a bad speaker or such).

Another rule that is used is this: If the repair cost is over 1/2 of the replacement cost for a similar set, then replace it.

Hope this is some help. Sorry I can't give you a precise prognostication. If IC 301 was known to be the culprit - and we don't know that for sure - then you would be into a major repair getting that ic out and doing the diagnostic routines after its replacement. I think the replacement of that IC will normally run around $150; probably $75 for the part alone.

Let me know if I can help further.

    3 blinks....

    As a general rule, the blinking standby light means serious problems and you would be better off getting a technician involved.

    This set is a very expensive one and it has some life left in it. Further it is a Sony, so you will be wise to get it fixed.

    After studying the blinking codes, let me know if you have any further questions.

Finlux tv showing black screen after switching on by remote. standby light is flashing buy mo picture or sound


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

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.


Thanks for using Fixya.

I have a Sony Trinitron 32" TV. The picture don't


Hello
Blinking of standby light in Sony sets are fault indications. You just count the number of blinks occur at a time, by switching the set ON-OFF by its front panel power switch, not by the remote control handset. Just do it for at least three or four times, count the exact number of blinks occurs there, and inform it to me through Fixya. Through the number of blinks, I can locate the faulty section, of somtimes to the exact fault location. Count it keenly and inform me. OK.

Hello
Blinking of standby light in Sont TVs denotes fault indication. You just count the number of blinks occurs each time you switch on the TV. Please switch it ON and OFF by its front panel power switch, and not with the remote control. Do it three or more times, and keenly look at the number of blinks; confirm it, and send it to me through Fixya. OK.

Sony Trinitron KV-28LS36U no sound or picture, the standby light flashing green and red but if i switch it on a little bit of sound comes and then switches off. how can i repair?


The unit is shutting itself down because a problem was detected internally. When this happens, the standby light should blink a repeated pattern. Please count the number of blinks and post the number here. That will indicate the circuit in which the problem occurred.

Here's an excerpt from the Sony Manual online. And the link - http://esupport.sony.com/US/perl/webtree.pl?template=EN&mdl=KDF55XS955&content_id=68&category_id=11&problem_id=52

The POWER/STANDBY (red) indicator flashes three times
If your power/standby indicator is flashing in a pattern of three flashes, this may indicates that the lamp cover is not attached securely. Follow the directions in the Operating Manual under changing your lamp that related to closing and securing the Lamp Cover. Ensure that the Lamp Cover Door is securely fastened by tightening each screw.

The POWER/STANDBY (red) indicator flashes continously
If your power/standby indicator is flashing continuously, and the lamp cover has been secured, your TV may be in need of service.

The POWER/STANDBY indicator is lit up green (not flashing)
A sustained green light indicates your TV is on.

The POWER/STANDBY indicator is lit up red (not flashing)
A sustained red light from your power/standby indicator simply indicates that your TV is in standby mode. This shows you that your TV is ready to be turned on with the remote.

Is it the power light and not the lamp light? If the lamp light is flashing then replace the lamp.
