Westinghouse tv stopped working


Hi

If no standby light is on (red), maybe a blown fuse that can be replaced with a new one of the same value. If the blown fuse is blackened, some componet is bad inside the power supply.
If the fuse replacement does no result, the problem may be in the power supply (IC power supply switching controller, switching transistor, startup resistor or even an overload in the supply line output) which requires a technician to fix it.

How to repair a fuse blown hisense tv set


Hello
If the fuse inside the set has blown up, there must be some reson for that. If it has been blown up due to a surge voltage, replacing the fuse will make the set right. If there is some short circuited components in the power supply regulator section, the newly inserted fuse will blow up, as soon as you switch ON the set. If so, thorough check to power supply section should be done, before replacing an other fuse.

My TV just turned off and the red power light started to blink, why?


In most cases this error will dissapear by switching your television off at the wall and then switching tv on (via power button on TV front/side panel) "Whilst still switched off at wall outlet"

This will discharge all capacitors inside the TV

Now turn TV power button off then switch back on at the wall outelt then try to resume watching TV.

This solution may clear the blinking red light however if it does not it could be a more serious issue such as a blown fuse or even blown control circuit on the TV, In this case you should decide whether a repair is economical or to replace the TV.

This solution is based assumption this a CRT television and not an LCD.

Hope this helps

T V will not turn on, with the remote or manual...


Make sure there is power at the outlet, check external fuses such as plug fuse, then DISCONNECT remove back panel and check for blown fuse inside the set. If you find a blown fuse replace with same type and see if it blows when you switch it on. If it does you have a power supply or scan board fault and an engineer will need to diagnose.Sometimes fuses just fail due to fatigue if you are lucky.
DO NOT TOUCH WHEN CONNECTED TO THE MAINS, , in fact take care even when disconnected as you can sill get a shock from charged components.
THERE IS VERY HIGH VOLTAGE IN THESE SETS, 25KVolts for the tube so take care.
I hope I have been of help but please do not hesitate to ask if you have any further questions.

Main fuse blown on CT-32G11 32" Panasonic TV, Replacement fuses continue to blow.


If the main fuse keeps blowing, check the horizontal output transistor for a shorted condition and diodes in that section as well.

Tv wont turn on


Hello tvlover, The outage actually is not the problem but the spike that happened when your power came back on did the damage. That aside, you may just have a blown fuse. If you are able to and feel comfortable work with electronics, with the TV unplugged from the wall, take the back off of your TV and take a look at the line cord going into the circuit board, this will lead you to a fuse holder, look at the fuse and see if the filament inside has been blown (opened). If the fuse is blown relace it with one of the same amperage and voltage which should be written on the metal part of the fuse. Once the fuse is replaced, plug the power cord back into the wall and power it up. If it comes on and plays, that was your problem and you can turn the TV off unplug it and put the back cover back on, plug your TV back into the wall and enjoy. However if the fuse blows again, that could indicate a problem with a short somewhere in the powersupply path and that will require troubleshooting the set. Now I we have to troubleshhot this TV you will need a multimeter, an oscilloscope, and a schematic of the TV (at a minimum). If you do have electronics experience to this level and do not have this type of equipment, You will have to take the TV to a repair shop. Thank you, and I hope that it is just a blown fuse.

FUSE SPEC FOR SONY KV-36FV16


The rear panel nameplate will state the unit power requirements. Look for number of amps draw. Let's say you read "2 A". Now, depending on where in the circuit this fuse is, your fuse size will be no more than two amperes (sometimes slightly greater if slow-blow fuse spec'ed). So, if your fuse is located immediately near the line-cord entrance to circuit board, start with a 1.0A fuse. If that immediately blows, then increase to a 1.5A fuse. Repeat until 2 A fuse is reached. If still blowing, then there is a problem with the set, either power supply or tube.
