Hi what kind of the fuse is in this tv cause i oppened the tv and removed the fuse and now i have lost it and dont know what kind of fuse it was! Do you have any idea?

Not sure what issue is: it turns on then quickly off?

short in power supply or more commonly in the high voltage area---bad solder connections (age of set does not matter) are also very common.

hi,
your dvds samps switch mode power supply has some complaint. remove the power and oppen its cover and check the fuse inside.if it found blued, maybe the smps driver mosfet or the MOV aftre fuse may be damaged. MOV is a component which blues the fuse if there is an over voltage surge over the specified limit. if found faulty replace it.
ok

Hello cwcritters, hi, does your tv front panel has any pilot light on or nay sign that the TV is on, if yes, there is problem with the main board and power supply, probably a short, this TV is on standby, here are the things to check, a shorted horizontal output transistor, a bad voltage regulator, or any ICs that are overheating, NOW if there is no light at all, then your TV may have fuse open. A fuse opens when a user plugs the TV while the power switch is on, causing a surge of electric current. or TV develops a shorted regulator. If you dont know anything about electronics, dont do the service yourself, you may further damage the TV, better call service.

Hi

They have so many reasons why blown fuses in TV... all you have to do is to check the shorted semiconductor like regulator and drivers..

Thanks!

Your main fuse blew if its dead but it could have caused other issues with an electrical spike when the power went off, this is kind of common..pull the back, replace the main fuse and see if it blows it again, if it does then the diodes in the hot side of the power board are bad and would need replacing.

On your normal mid range amp it uses 20 amps, but on your up scales amps they use 30 amps

If you don't have any indicators working, you have probably lost your power supply. With no picture and no sound the chances are you have either lost the power supply or blown a fuse. If you remove the cover and look at the circuit board there is a fuse located near the rear of the chassis near where the power cord connects to the chassis. If the fuse is blown, it is advisable to replace your damaged power cord before replacing the fuse. The cord could have a short and this could create a fire. Be very careful when working on any television. Be sure it is unplugged for more than one day to allow the high voltage to decay from the picture tube. Do not touch the picture tube, it still may have some residual voltage and could shock you. If you replace the cord and fuse and still have the same problem, you will probably find that the high voltage transistor is bad and needs to be replaced.

C702 102K / 2KV capacitor shorted,located near transformer,

possibly partly covered with glue.Use Sony part # 1-161-754-00

102K / 3KV for replacement. Check E994 pico fuse ( 2 amp ).

Let me know by rating my suggestion....T.

sounds as you lost the firmware in the set or its corrupted and theres no way to fix this as I know cause they dont have any ports yet that comunicate with the microprocessor . best advice i can give is replace the Microprocessor and the eeprom IC Good Luck
