I have a 60in phillips magnovox rear projection tv model number 9P6040 C104. The green power light comes on but I have no video/audio. And it makes a chirping type sound. Could someone please gice me some...


Your problem seems to be convergence. This has to do with the video/ audio. If your Tv has no video/ audio and make a chirping sound when you turn on the TV, the problem is within the convergence chips. The symtoms you describes gets to the heart of your tv issue. However your tv can be fixed and it does not have to cost you an arm and one of your legs. If you think you can tackle this repair by doing it yourself then I suggest giving it a go. You can order the kit (audio/video)repair kit/chirping. The cost is reasonable, $68.00. It comes with all the replacement parts and thorugh instructions to guide you through the process. Give it some thought if you think you can fix the tv, if not have a professional do the job. Good Luck.

Sound , but no picture


It sounds like the problem is in the circuit board. The TV should go in for professional repair - electric shock is no fun. Good luck.

Air Flow is blocked and TV will automatically shutdown. The air flow is not blocked


If the airflow is not blocked then indeed this is a sensor or a fan issue your going to need to ether have a repair guy come out and investigate the issue or get yourself a service manual and try doing the job yourself.

We beleave its a sensor by what you described.

I have a Mitsubishi hd 1080 series 60 inch model # vs-60111


G'Day!

What you're describing is a repair issue. Unfortunately, there is nothing you can do through troubleshooting to correct that problem. There is an internal part that has to be replaced. If you're under warranty or have an extended service plan, the repair will cost you nothing.

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 post a comment if you need further assistance so that I can help you further.

My TV is showing a double picture


If the picture looks like a 3D one, the problem is a convergence issue. This can be as simple as poor connections at the pins of the convergence ICs or defective ICs. If you can solder you can probably fix this yourself. Please note that there are potentially dangerous high voltages inside the set even when unplugged.

If you wish to attempt the repair, please update this and I will provide additional details and instructions.

Magnavox 51" Projection TV Red Convergence


he is most likely trying to rip you off. You need to replace the convergence ICs. Theres a kit at the following link for your model that has both ICs and the 12 feed resistors plus step by step instructions to do the repair. Heres the link. this is the kit your model uses. http://servicemanuals.vstore.ca/product_info.php/pName/phillips-dptv-305-dptv345-convergence-repair-kit/cName/convergence-repair-kits
A convergence problem such as your describing can blow a fuse if you try adjusting it when the ICs fail. and its all centerd on the SSM panel the LSB panel wont be affected. Alot of TV repair men dont have a clue they just try to sell you some boards instead of repair the issue.
