At first, the t.v. had a delay before it came on. Now there are several clicks and the set will not power up.

I think it blew out ,how can i know for sure and if so how do i fix it


If the power supply has a burnt electrical smell, then it has failed.
I do not recommend you to repair this power supply, mains voltage equipment are dangerous if you do not have the electronic knowledge to repair this type of equipment.
I suggest you purchase a new switch mode power supply, with a capacity of the same wattage as the existing power supply or higher (higher wattage would be better especially if you are operating near the maximum limit of the old power supply).

Dropped Averatec 3200 laptop and it fell on the cord and bent the power source connection. Can I fix this or do I need to send for repair?


I've had this happen to me a few times. If the pin inside the laptop is bent, then there is no question that you'll need a warranty or shop repair on the laptop to fix or replace the power port.

If the power input coming from the power supply is bent, then you can try fixing it by pushing the plug back into place with a pair of pliers. If this doesn't work, then you'll need a replacement power supply or repair.

I am looking to have multiple power supplys repaired. Do you guys do this? 3y and Delta power supplys


Generally power supplies are difficult to fix if something's wrong, and it probably would cost more than they're worth. You're better to just spend the money on new ones. They aren't too expensive to replace. Unless it's something visible on the outside like a fraying wire or a broken connector, which can be fixed with a bit of solder and shrink tube or maybe an extra connector, you're better off replacing than repairing.

AC adaptor for 32 inch Protron TV


It seems a lot of people are having problems with the Protron power supply. I’ve been able to repair all the ones I’ve seen so I’m confident I can fix them. I don’t sell the replacement power supply but I’ve heard about the ones on EBay. They seem to be a mishmash of two power supplies (12vdc and 24vdc) wired together with the proper connector. This should work but it just doesn’t sound very clean looking to me and they end up costing $150.

I’ve been charging between $50 and $100 to repair these power supplies. My recommendation would be to send me the power supply I’ll check it out and unless it’s unusually damaged it will cost $50 plus shipping to repair. If I can’t repair it I’ll return ship it and only charge for shipping.

I will guarantee the repair for 1 month. I don’t know what’s causing the power supplies to fail so I can’t guarantee it any longer than that. My feeling about the reason the Protron power supply stops working is two part; could be overheating due to lack of proper ventilation to the power supply; or the TVs power requirement is overdriving the power supply.

Feel free to contact me if you have any questions.
I repair these at my work, so here’s the shipping address:

Dave Simpson
23372 South Pointe Dr.
Ste. B
Laguna Hills, CA 92653

Also, I’m set up for PayPal.
