I have a Sony KV-32HS420 projection TV. When you turn it on you hear a click and the sound comes on for an instant but the picture remains dark. The standby light then blinks 7 times and then repeats 7 blinks repeatedly.

Hi.

The TV clicks and shut down because an internal fault is detected. This cause the TV shutting down and going in protect mode.

To start ensure that you go through the basic troubleshooting illustrated here: Why my TV does not start up?

Basic troubleshooting consists in disconnecting the power cord for fifteen or twenty minutes.That will hardly fix the problem, but must be done.

If that does not work, 7 blinks means that there is an horizontal deflection problem.
This is usually caused by faulty convergence ICs. Both the convergence ICs located on the D board must be replaced. The Pico fuses located near to the ICs must also be replaced.
Job is done de soldering old components and soldering new ones on board. Better using soldering compound to do the job.

The ICs to replace are marked IC8002 and IC650. They are both MCZ3001D (power amps). The ICs must be de-soldered using a proper iron. The cost of each IC is about $15, the labor is about $100/$120.

If you want a quote on repair or if you want to contact a qualified technician ring the number listed on the owners manual or see Sony eSupport

You may have a problem with the capacitor. Normally the ones on the power supply circuit are the first ones to go out. Have it inspected for leaks or swelling. Also check out the unit for burnt resistors.

You have what is commonly known as a shutdown problem. It's an overload in one of the internal circuits. It needs to be looked at by a professional tv reapir person.

Sounds like you've got a short in your house electrical lines. Try using a surge protector (AKA power strip) between the power cord and wall outlet. If you've already got a surge protector, try replacing it.

Get out your original remote and hold the "Setup" button at the same time as holding the On/Off button on the TV set. It just worked for me!! Thank goodness.
