20 Most Recent Sony FD Trinitron WEGA KV-30XBR910 30" TV Questions & Answers

Issue is with either the reader or software. Try replacing the hardware or just disconnecting it to see if indicator goes out. If it does then that would seem to confirm that the issue is with the hardware.

Either change input or hit display button on the remote to remove it from the screen.

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.

• 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 is a High Voltage fault or power supply fault.
Hope that helps.

Hi there
To answer your question;
In sony tv`s the seven blinks(sony error codes)usually means a high voltage safety shutdown( h.voltage has exceeded 33k volts) and is usually caused by the power supply regulation and/or the horizontal deflection circuit.
Which means that some repair will have to be done before it turns on again.
Hope this help. Happy Holidays

The three blinks code(sony error codes) indicates a problem in the power supply. In your case since you manage to turn it on after a while it may mean that you have weak capacitors or bad solder joints in the power supply.
Hope this help Good luck
Please do not rate this answer(unless it helps) as it is only a suggestion/information.

I have the same set, and same problem. After many hours/days of reading about this issue (which seems to be a popular one for this series and others) I have found a few sites that have detailed info on what can be done. This link is for a different set but the same issue. http://www.agoraquest.com/viewtopic.php?topic=1121&forum=34&start=80&select_page_number=9
This problem seems rampant on many Sony sets. There really should be a class action suite against them for the replacement cost of the parts which can be $400(USD) or more unless you are handy with a soldering iron.
I have a service tech coming by to look at the set soon ($75) so he can tell me what is actuall wrong with it. Once I know if it is the D-board or the usual 3 ICs that die. I will most likely have a friend of mine solder on some sockets to replace the ICs if the happen to die again.
Good luck

Check for dry capacitors on the horizontal side

1. See the ugly red color bands on the television set? These can also occur in blue and green. We're going to fix these!

2. Front shot of the television. Their are two screw holes on the front of the unit near the edge of each side right next to the speaker grille.


3. Close up shot of the screw hold. It is covered by a plastic cover that has two tabs holding it in. Carefully pry them out with your flat head screwdriver. Do not apply too much pressure or you can break the tabs off. Once the covers are removed, unscrew the two screws with a Philips screwdriver.

4. To remove the cover, pull from the bottom of the front case and rotate towards you. Once you rotate it out, the top will disconnect and come loose. Do not pull it off, as there are cords attached. (see picture) Loosen the cables attached with the twist ties and set the front cover to the left side.


5. With the speaker grille and cover removed, you now need to remove the wood panel to expose the inner electronics on your Sony HD TV. To do this, remove the four Philips head screws from the panel. Then, pulling from the right, rotate the panel off and the electronics will be exposed.


6. This is a picture of the inner electronics of your Sony Rear-Projection High Definition television. The little black box towards the front of the unit is where we will concentrate our time as it is the control for the voltage & convergence adjustment.


7. When focused in on the controls, you want to concentrate on the bottom row for the voltage / ray gun projection adjustment. The colors are labeled below and from left to right are blue, green, and red. Choose the one that needs to be adjusted and turn ever so slightly with your Philips screwdriver to remove the lines. In my case, the red just needed to be turned 1/8 of a rotation to be back in adjustment. Do not turn to quickly or abruptly or you could possibly damage your TV by varying the voltage too quickly.

6 blinks meens no horizontal and no raster check capasitor c515/c516/ jungle IC and IC206.

You cannot use sub parts on sony use sony parts only. Same with hori output transistors. USE SONY PARTS ONLY.

SOny has had big problem with BAD picture tubes so when tube begins to short in return it will burn flyback transfomer ,shorting out hori output.I know i thru away better then 50 sonys all with same problem. some of them where only a year old!

The 7 blinks indicate a safety shutdown due to over-voltage in the high voltage section. The high voltage has exceeded 33,000V. This is usually a problem with the power supply regulator. I need to look up the specific part for you. If you are comfortable working inside the set and can solder, you should be able to repair this yourself.

Dan

Good day.
Your unit has issues with the high voltage section. Particularly the vertical and horizontal sections. Blinking lights indicates that your flyback is not osscilating to distribute the supply to the sections. Please have it checked by a repaiman.

Question edited for clarity. This is unlikely to work, although I do see the remote has a VCR/DVD Source button. https://www.amazon.ca/Players-Kv-20Fv300-Kv-27Fa310-Kv-32Fs320-Kv-29Fs120/dp/B0874DLQMP And Sony says it is not programable DVP-NS57P The model is not programmable. https://www.sony.com/electronics/support/remote-control-programming/models/dvp-ns57p https://www.google.com/search?q=sony+dvd+remote+codes You can buy a Copycat remote for the DVD Player if yours is lost. https://www.google.com/search?q=DVP-NS57P+replacement+remote ..

This TV is 10 years old and probably requires a service that replaces the backlight invertor or just a power supply issue. Check to see if the light blinks. (That is the fault code and then google the result for more information).
