Re: Wont turn on

Most moulded plastic plugs have a rectangular piece of plastic that sits inbetween the 3 pins. Using a flat bladed screwdriver you can prise this out and remove the fuse that sits underneath.

Best way to check if the fuse is bad is with a multimeter, however if it is a clear glass fuse you should be able to see if the thread inside is broken. Since fuses are so cheap you are as well putting a new one in anyway, however you must be careful to replace it with a fuse that has the same current rating. If you are unsure take the old one to an electrical shop with you and the staff will help you.

Tv model #46h84 wont turn on no picture or sound

Assuming thar you can open the tv case and deal with electronic parts, you should first check the main fuse. If it is OK, check the anti-surge resistor (generally 3,3 Ohms/5W). One of these components may be bad. Before replacing the bad one, check for short in MOSFET power switching transistor, fast output rectifier diode (+ or - 90V line voltage). After findind out the culprit replace the bad components a afterwards plug in the tv and test.

Good luck. I hope this will help you.

HI there,

Check for any bad solder on the mainboard of the TV, and also check for any burn fuse on the powersupply area... BAd solder was very common problem on Mitsubishi TV..

Tv wont turn on

This is a general failure indicator and can be anything from a blown fuse to a bad power supply/vertical IC/lightning strike.

There are 2 fuses, check/replace both. if they blow again, check for physical damage to the vertical IC LA7832. If its cracked or had a hole in it , you are going to need to take it in for service.

Picture on screen wont stay on

could be noumerous things: 1. check power supply, too high or too low voultage may cause TV to shut down. measure it to detarmine if power supply is faulty. 2. check convergence board. If either of these 2 fuses on the convergence panel are open then replace the STK output devices PLUS check for any resistors in that circuit that may have overheated and changed value. Use actual fuse values, putting in a larger fuse, even to try and diagnose problem, will cause more severe damage. 3. Check for bad solder connects on the PC board in the area of the power cord and related components.

Av32D104 JVC Television Wont turn on , Has power to light on front that reads "auto timer" what now?

Unplug the tv set for 30 seconds, plug back in and turn set on, if its wont fix the problem, and you're NOT under warranty 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!
