Re: TV not working

The symptom is usually caused by a breakdown in the power supply circuit. in most modern receivers (transistorized and/or ic), it may also be caused by a breakdown in the horizontal deflection circuits (hor. oscillator, pre-drive, or drive circuits). supply voltages for the tuner, video if,sound if, and vertical output are usually supplied by the horizontal output circuit. but if you doesnt know anything about these stuffs, better bring it to a qualified service tecnhician.

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.

Im having a problem with my TV turning off and the standby button flashing 7 times, after it shut off. What can I do.

Blinking led in sony tv is its self dioganising function. 7 blinks by it means the horizontal output voltage increased above 33k.
You have to check the power supply stage of you tv. Normally in sony tv dry soldering can happend in the power supply stage. It will lead to unregulated voltage output from the power supply. Resolder all the points in the power supply section it will solve your problem.

KV-36XBR400 won't turn on, "standby/stero" light

You are correct. You are right about the power supply and replacing with led hdtv. You will be happy with a Samsung led. Time to upgrade.

I have a Sony Wega KV-34HS420 TV that takes several tries to turn on. When I push the power button or remote power on I hear the normal click and the sound comes on for 3-5 seconds but then I hear a second...

Since the set appears to "recover", it suggests either a poor solder connection or bad cap somewhere in the power supply. The 7 blinks indicate the problem circuit is in the horizontal area. Check the regulator (STRxxxx) IC in the power supply. If you do not have experience working with TVs, please refer this repair to a shop. The regulator IC costs around $25.

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.
