Standby light blinks 7 times on my kv30hs420 is it worth the repair

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 stage 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, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy.

Problem with Sony FD Trinitron WEGA KV-32HS510 32" TV

Blinking of standby LEDs to Sony TVs are fault indications. Form the number of blinks occur at one time, the repairman can get an idea of the faulty stage inside it. According to you, it blinks 4,6 & 7. Just visit this site, It has details about blinking codes to Sony TVs, both CRT based, Flat panels and Plasmas. I can't provide more advice to you, because the number of blinks are not constant. Check the site, and get it.

Standby LED blinking 6 or 7 times and TV won't turn on

That is an error code that tells the tech where the problem lies. It is probably somewhere in the power supply stage. Your best bet is to take it to a TV repair shoppe and let them deal with it. They have all the documentation in order to repair the unit, and they can tell you what the problem is before they work on it.

2 year old turned tv on/off several times - TV doesn't turn on

The main power supply is in the protect mode. Usually this is caused by the high voltage section, scan amplifiers, and or the main power supply failing. Many times, when there are failures in the scan amplifier output sections, the main power supply can also be damaged.

On rare occastions, the CRT electron-gun can have a short, and cause this type of failure condition.

An experienced TV tech should be able to service this for you.

36 inch sony wega trinitron

I had the same issue earlier this week. 4 year old sony trinitron wega 32 in. I was told by Sony to call technician to repair and have called tech....could be anywhere from $200-$300 repair. I did research the blinks (google "sony blinking codes" to find out what each means) Ours was 6-7 blinks which meant power surge to tv. I advised to Sony that i saw many of the same issues with many of the newer tv's and suggested a recall issue--they denied and where no help.
I will buy a new tv now--definitly not a Sony.

Blinking what - how many times before it pauses and then blinks the next set?? Sonys have an error code of blinking to help isolate the problem... (count the number of times it blinks before pausing and let me know).
