You need to check the power supply area. usually when a fuse blows, that means the bridge rectifier is blown or the ic in the power supply area is blow too or both are blown.check there..good luck

Some RCA models had problems with there degauss circuits drawing to much current at turn on. You can change the fuse to see if it will work for a while. If it immediately blows the fuse at turn on or at plug in, there is a hard short somewhere. If it works for a while and blows the fuse again, take it to a repair shop and have them modify the degauss circuit. An up to date shop will know what to do. Should not be expensive.

all sets must have rated fuse for protection. some units now use what is called a PICO-FUSE.this type of fuse is soldered into the pc board. usually marked with location i.d. F301,F901,F400. etc. these fuses look like resistors or in-line coils. check continuity w/ohm meter. if new fuse blows as soon as you plug in tv, suspect bridge diode ciruit or main filter cap(large ripple filter by main fuse. if new fuse blows when you try to turn on, suspect 130v regulator or high voltage short(horizontal-output, flyback transformer) good luck!

Hi there!

Dead short in the power supply, possibly the rectifier or the PTC has failed. PTC located in the Primary supply at the point where the coil around the tube plugs into the Main board. Two terminals to be exact. Normally cream in colour if it is an original Philips PTC. If the rectifier is short you may expect to have more items blown. Good Luck, Regards, JUS004

Keeps blowing fuse

It has a short circuit somewhere...
Not sure if this is a CRT, LCD or Plasma TV but the two common causes of shorts for CRT's are the Horizontal Output Transistor (HOT) and/or the Flyback Transformer (Could be both). As a general rule if the flyback has visible cracks in the case they should be replaced. It is also a good idea to replace the HOT if you're replacing the flyback as it could be weakened and may not last much longer itself.
Other areas to check for all types would be any Diodes in the Power Supply Circuit. If a diode is open it can cause the fuse to blow. Note that a diode itself will not short, but an open diode can cause a fuse to blow.

Sony Triniton Fuse Blows

You will have to trouble shoot the board down to the component level I'm afraid. I would for sure pull out the transistors or the FETs to get a good reading on the parts.

whenever fuse blows every time it is the indication of short circuit in tv. so please do not put fuse unless you know the cause of blowing fuse. these are the reasons of blowing fuse. 1 main filter cap.short. 2 rectifier diode short. 3 swithing transistor short 4 horizontal output transistor short 5 caps & diodes connected to flyback transformer short. 6 print short. 7 at last if every thing ok then flyback transformer defective. hope this will help. if you are not a tech person call skilled tech to fix it. good luck

Could it be in the HV circuit? first you isolate h/output section from power supply. make power supply output ok. check h/output section for short circuit 1 print short near eht 2 diodes or cap.near eht 3 yoke H winding just by removing connector 4 EHT transformer regards

Not turning ON, fuse blows.

In most cases, it is either a shorted component in the power supply or a shorted horizontal output transistor. It will take experienced electronic troubleshooting to fix it. TVs have lethal voltages (both 110V and 25,000V kind) and improper repair can result in shock, injury, or the emission of X-rays by the TV! Be safe and either replace the set or have a shop work on it for you. I'm a tech with over 25 years of experience, by the way. I appreciate honest rating of this reply if you find it helpful.
