Is your TV now Working?

Hello, I am having the same that you are/were having with your TV. Seven blinking standby lights. Did you do the repair yourself or did you have a tech come out to your house. My TV just went out last week and a tech said it will cost around $300 to fix the issue. Thank you for your time. Brandon

My tv whe I turn it on will only stay on for 4 seconds and then turns off, and the stand by light is on and blinking.


Have you when set turns off and standby or power light flash to count here the blinks if in a sequence like seven blinks, pause etc? This se should have the error buffer.

Dear John,
Welcome to 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. I think it helps

My standby light comes on and blinks seven times repeatedly but no picture.


Hello
Seven blinks of standby light in Sony tv denotes that there is a high voltage problem. It is otherwise called as high voltage shutdown.
Normally 32" tvs has an anode voltage of 27,000Vdc approximately. If it rise beyond its limit, the microcontroler in your set will detect the high voltage, and will prevent it from working further, to protect you fro X-Ray emisson as well as to protect the TVs other components inside the ciircut board from further damages, and will inform you about this fault, by seven continous blinkings of standby light. Now you are seeing this.
The final anode voltage depends very much on the input DC voltage to LOT [Line Output Transformer]. Usually this supply rail will have a voltage level of 135 to 140VDC. If it rises above this level, extra high tension voltage generated by the above said LOT will also rise proportionaly to high, which will goes to the final anode of the picture tube. If this voltage goes very high, there is a chance to radiate X-Rays from the picture tube which will harm you. This high voltage protection also known as X-Ray protection.
The main reason for this fault is related to the regulated power supply section inside the circuit board of your tv. To repair this, you have to open the back cover of your TV. Take every precautions before doing anything to your TV as it is an electrical equipment, which generates high voltages inside it while it is working, and there are voltage points as high as 30KVDC [30,000VDC], wich is very dangerous.
Just open your tv, and locate the power supply section. It is very easy to locate, as the main supply wire goes into it. There will be a regulator Ic, normally Sony sets have STR numbered ICs are used in that section. This regulator will heat up to 75degreeC, and there is a chance to get loose the solderings on its leg points, as continous heating and cooling process. Just look for any loose solderings on the solder side of your TVs power supply section. In practice, I found this in too many Sony sets, during my 36 years in this service field. It is very difficult to detect the exact loose point, so I always do is, just resolder most of the suspected points on the pcb, by applying a little more solder, and will retify the problem. Moreover, just replace small electrolytic capacitors fitted on that board, because some of them may cause this voltage rise. The DC supply voltage rail, will be between 135VDC or so. Any fault in the components fitted around the above said STR will cause this problem. So check every components, and replace if needed. If this does not help replace the STR with same type and number.
Go further with confidence. You can and you will. Wish you sucess. Take care. OK.

Triniton tv no longer working standby light blinks seven times. why is it on standby?


Could be a fault in the powersupplym could be a flyback issue it will need to be evauluated to see what is the cause now most shops will tell you what it is without charge that way you can decide to repair it or replace it I am telling you it could be a power supply issue or flyback I will need to look to rule it out but at least you know what the problem could be and determine the cost of repair. please do click the end session to your right,

if you have the circuit diagram of your tv,check the horizontal polarisation IC closer to the line transformer and replace it.If it doesn't work,send the question again.

KV-32HS510 and KV-27HS420, seven times blink error code shows problem in Horizontal deflection circuit.

There are many possibilities like dry solder joints, weak capacitors, Horizontal transistor short or flyback transformer fried etc.

If you have little experience of TV repair and good solder skills and have necessary tools to test / check defective parts, then you can make it. you also need to have related service manual to see board location, schematics and part numbers.

Sony Vega Service Codes


The 7 blinks indicate an over voltage condition. The high voltage section has exceeded 33,000V. This is generally caused by a bad regulator. I don't have a listing for your model, but there should be a multi-pinned IC attachd to a heatsink marked STRxxx located close to where the AC cord comes into the set. Post the actual marking here and I'll get you the part number and cost. That is the regulator that may be the problem.
