Question about Philips Magnavox 27MS343S 27" TV

Blown up tv (philips)

I work for a small electrical company that had a job with a department store. One of the electricians was in a hurry and did not label his hot and neutral wires for a large area in the electronics section of the store. Someone else connected the wires to the panel which was three phase. Long story short the hot AND the neutral wire feeding the receptacles for a row of LCD TVs ended up both being hot thus sending 208 volts to them. They all blew up. Our company fired the electrician and bought the TVs. They have been sitting in our storage for almost a year. My question to you is- can they be fixed. I wondered if maybe there is a fusable link inside the TVs designed for power surges that took the damage and can be replaced. Are these TVs fit for the garbage can or is there an easy way to fix them? Thank you for your time. Ethan.

There are fuses always inside TVs. The main filters (capacitors) are probably damaged and the regulators are probably blown. Chances are the rest of the set is OK. Sudden bursts like that usually kill the fuses very fast and the regulator takes the brunt of the load. With a multimeter, you could probably check regulators for shorts and replace fuses.

If you're NOT still under warrantee you should at least open the TV and look for a blown fuse near where the power cable enters the set. A lot of times you can buy replacement fuses at a local electronic or hardware store and they're easy to replace.
Check the fuse. If it is blown, it will be obvious and make sure that the set is unplugged before replacing it. If it blows again, or if it is not blown, your problem is probably in the 'X' volt regulator and you will need professional help with the repairs.

You can also check the board where the components are mounted and resoled any that look bad. Brief power outages may cause the TV to turn off on its own. If you are using a surge protector, try connecting the set directly to the wall outlet.

In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint at the horizontal drive transformer.
All can be replaced at a local electronic or hardware store and they're easy to replace

If this does not correct the problem, you may need to have your TV serviced.

good luck!

How to find a good electrion

Hi Gladys,

I'm an electrician and would like to help you out. You should contact your friends and nieghbors to learn of the experiences they have had - both good and bad - with electricians.

Ideally, the work they had done was similir to the work you need to have done for a good "apples to apples - oranges to oranges" comparison. Next, you can contact your community's Better Business Bureau. Their recommendation is only for companies that have PAID them to be listed - however - they will tell you how many complaints, etc. they have had with the ones you ask about - so a "recommendation" from them really has little to do with the quality of the work the company performs.

Angie's List is an online data base of all kinds of service providers that many people swear by. It does cost to join however, so if your project is only a repair or small job, it may not be the best way to go.

Yelp is a free version of Angie's List (but it is NOT affiliated with Angie's List - just to be clear). Here, you'll find ratings from antone that cares to write a review on a business - from Pizza Joints to Dentists.

With these sources, you should be able to get a fairly good idea of the reputation of the electricans in your area. I hope this helps & good luck!

I want too lear too instal current at home,ect

Becoming an Apprentice Electrician, and/or moving on to a Journeyman, then Master Electrician, involves either going to a Vocational Technical, (VoTech), school, or learning on the job.

As you work on the job, you will be under the license of an electrician. After you learn your craft to an extent, you can take a test for becoming an Apprentice Electrician. Then after two years on the job you ca test out for your Journeymans Electrician license. You will be tested in the Residential, and Commercial areas.

See if there is a company that is willing to hire someone, who wants to learn the Electricians craft in your area.

Tips from me:
1.When working on a circuit, NEVER assume the power is off. Even when you are sure it is.
Use your test equipment, and make a quick check before you put your hands in there!
Has kept me from getting shocked for many years now.

2.After making a wire connection to the breaker, before you insert the breaker in the Service Panel, wiggle the wire a little. Then try to tighten down the circuit breaker screw, a little more. You're dealing with Alternating Current, (AC), and AC vibrates! It can eventually vibrate screws loose! (50 to 60 Hertz. Hertz means Cycles per Second)
