Check whether the filament of the picture tube glows. If not, check all the solder terminals to CRT base socket. Check the serial resistor connected to the supply voltage to filament. . Check the continuity of filament with a multi-meter.If you are not familiar with electronics, do not attempt to repair! Whether you suffer fatal electrical shock! Instead, contact the nearest service center!

You likely have bad solder connections around the tuner area. This model has a history of problems in that area or the tuner itself.

SOURCE: Sony KV-32FV15 TY

I have had my Sony KV-32FV15 for about 2 years now and nothing has ever gone wrong(even going through several moves.) I recently moved again and when I plugged in the TV, you can hear the sound perfectly but the screen just stays black. You can not even hear the squeal that the TV makes when comming on. Is there anything that I should initially look at to troubleshoot. I cannot afford at this time the $250 fee to repair my TV. I look forward to your input and hopefully I can get this TV working again.

I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with
troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.

If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one
circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.
