There are tiny screws in the back of the tv if you make sure you locate all of them and remove them carefully the back lifts off without causing damage. Make sure you keep note of which ***** came from which hole as the screws very in length!
We got our fuses from an electrical wholesaler Maplin.
Hope this is of help?

When i turn on tv it keeps shutting back off

That is the internal safety switch, that detects a fault and keeps tv off.

Try first unplugging power cord for one hour.

If it does not work it means that there is an internal fault, probably a faulty component or a board in need of replacement.

If you need to call a technician you can ring the phone number listed on the owner manual.

If there is an error code post here

Tv bord fuse damage replace the same type again damage what problem

A fuse does not trip to annoy you. It trips because the circuitry is taking to much current. This can be just a little to much, taking it to trip after a few minutes or hours, or lots to much, tripping as soon as you switch on. Can be caused by a defective semiconductor, or a capacitor with a shortage. If you can't see anything wrong on the board, like a capacitor, wilt a rounded head, or a burned out semiconductor or even a resistor, you have to find out by measuring what could be wrong. Without the skills, don't even go there. It could be dangerous because of the high voltages in the TV.

Cause of blown fuse

Blown fuses are due to sudden power fluctuations and/or short circuits inside the TV. It is not advisable to replace the fuse, without checking for any internal shorts as it might damage more parts inside when making attempts. A qualified service technician will do a bulb check across the fuse to ensure there are no short circuits (The best way to do it).

Fuse keeps blowing on my Philips 32pw8608/12

Please, never try to replace a fuse, without checking for any short circuit inside. You will only increase the damage inside. It is advisable to call in a qualified service technician as opening back cover by unqualified personnel is hazardous.

Open your TV and chekc whether the fuse in the power supply board has blown out or not. If it has blown out, never replace it with same type; befor troublshoot the reason for the blown out for the fuse. There must be some reason for the fuse to blow out. Without rectifying it, if you replace it with a new fuse, it may cause more damage to the set.
The power supply board to your TV will look like this.1_10_2012_4_00_19_am.jpg

Does not power up at all no lights,

Try to check the fuse if not busted, the fuse is located at the main ac supply of your tv try t0 follow the ac cord and it will direct you to the power supply of your tv, it has two lines try to check or trace both lines to locate the fuse, if the fuse is only busted no burn marks try to replace with the same rating but if the fuse glass is covered with black that looks like something is burned inside dont replace it the other parts of your tv has a damage specially the regulator and the rectifier is shorted. Note before removing the back cover of your tv you should be sure that you unplug it first cause one mistake could cause serious injury. Good day and be careful.

TV does not come on at all.......would there be some replaceable fuse?

Certainly there will be a replacable glass cartridge type fuse. It will be there, not only for Sanyo, but for all TVs. The fuse used is for protection. That is, if anything wrong happens to the power supply or its internal circuits, fuse will blow up, and prevent further damage to other components. Therefore, you must understand that if fuse in your TV has blown up, certainley there will be some reson for that. Without find that reason, and rectify it, never put a fuse there, it it has blown. It will cause more trouble to your device. Check it well. Find out the reason for the blown out fuse. Rectify it first, and then put a new fuse there. OK.
