you can try just replacing the resistor, but I'm afraid you have other issues too because of this burnt component

What is the first step in troubleshooting color television? dead set..blown fuse..

You haven't specified anything about your Sony Tv. No model number or anything to compare. Although I hereby giving you a general trouble shooting method, first adopted by technicians like me. You have stated that the fude has blown out. Fuse will not burn out without any reason. it is a protective device used in every telivisions,as if any internal components inside it gets shorted, especially in power supply section, the fuse will get burned and protect the other components from further distruction. Therefore you have to trace the reason for the failure of fuse first.
You must beging it from power supply regulator section itself. Chech the resistance accross the main filter capacitor first. Set the multimeter in Ohms range, and the resistance must be above 250Ohms in one direction, and upto infinite in the other direction. If both readings comes below 20Ohms or so, suspect the power regulator Ic; usually sony sets udes STR type regulated power supply, and this STR will get shorted. As you haven't specified your sets model, I can't make sure whether it is circuted with STR or a switching transistor. As both cases, this regulator has a chance to get shorted. Desolder it out and check for short. if it finds shorted, check the rlated components also, such as zener diodes and resistors, for open and short,as they also will get damaged due to this main switching transistor, or STR; whatever may be.
Check the degaussing posistor for short. Check the rectifier stack for short. Check the mains filter capacitor for short. Check each and every diode for short. you must measure the forward reisistance of diodes with multimeter set in 100KOhms range. There shouldn't be any slight leak with this test. If it shows a slight leak, replace it. You just do these and inform me the result through Fixya. I'm ready to assist you furthermore. When you reply to me; please include the model number of your Sony Tv. Ok.

Tv will not turn on


If you have no indication of power(no lights,no clicks) the main fuse is a good place to start but if it is blown and is black in color you will have a shorted component ahead in the circuit and if you replace the fuse it will turn on as soon as you plug the set in.

If that does not work then check the transformer in the TV if it is not burnt. Replace if burnt.

This morning I tried to turn my RCA TV (model 24R411T) on and nothing happened. I tried plugging it into a different outlet, still nothing. I tried leaving it unplugged about 10 minutes and trying again,...


Power surges or nearby lightning strikes can destroy electronic equipment. However, most of the time, damage is minimal or at least easily repaired. With a direct hit, you may not recognize what is left of it!

Ideally, electronic equipment should be unplugged (both AC line and phone line!) during electrical storms if possible. Modern TVs, VCRs, microwave ovens, and even stereo equipment is particularly susceptible to lightning and surge damage because some parts of the circuitry are always alive and therefore have a connection to the AC line. Telephones, modems, and faxes are directly connected to the phone lines. Better designs include filtering and surge suppression components built in. With a near-miss, the only thing that may happen is for the internal fuse to blow or for the microcontroller to go bonkers and just require power cycling. There is no possible protection against a direct strike. However, devices with power switches that totally break the line connection are more robust since it takes much more voltage to jump the gap in the switch than to fry electronic parts. Monitors and TVs may also have their CRTs magnetized due to the electromagnetic fields associated with a lightning strike - similar but on a smaller scale to the EMP of a nuclear detonation.

Was the TV operating or on standby at the time? If it was switched off using an actual power switch (not a logic pushbutton or the remote control), then either a component in front of the switch has blown, the surge was enough to jump the gap between the switch contacts, or it was just a coincidence (yeh, right).

If the TV was operating or on standby or has no actual power switch, then a number of parts could be fried.

TVs usually have their own internal surge protection devices like MOVs (Metal Oxide Varistors) after the fuse. So it is possible that all that is wrong is that the line fuse has blown. Remove the cover (unplug it first!) and start at the line cord. If you find a blown fuse, remove it and measure across the in-board side of fuse holder and the other (should be the neutral) side of the line. The ohmmeter reading should be fairly high - well certainly not less than 100 ohms - in at least one direction. You may need to unplug the degaussing coil to get a reasonable reading as its resistance may be 25 or 30 ohms. If the reading is really low, there are other problems. If the resistance checks out, replace the fuse and try powering the TV. There will be 3 possibilities:

It will work fine, problem solved.

It will immediately blow the fuse. This means there is at least one component shorted - possibilities include an MOV, line rectifiers, main filter cap, regulator transistor, horizontal output transistor, etc. You will need to check with your ohmmeter for shorted semiconductors. Remove any that are suspect and see of the fuse now survives (use the series light bulb to cut your losses - see the section.

It will not work properly or appear dead. This could mean there are open fusable resistors other defective parts in the power supply or elsewhere. In this case further testing will be required and at some point you may need the schematic.

Tv repair

most of all. don't change the fuse if it was blown cause maybe the high voltage transistor is shorted, capacitors are blown, burnt resistor, or a grounding is bad.
And all of these may affect your TV's performance so much.
sometimes it causes fire. you don't want that ofcourse.

27GT722 Blows Fuse

There should be a part designation written on the board under that part. FOr example Qxxx or Dxxx. Can you post that here please? I can cross reference that designation using the model number to get you the part number, cost and description.

JVC AV-36260 Is there a fuse in this TV or is it a circuit breaker, if it is where is the fuse / circuit breaker located. I am am electrical engineer, but can not find any specs on the inside of the unit

All modern TV's have fuse devices,some glass,some chemical.

However,a blown fuse comes from a short circuit,which I'm sure

you are well aware.Let's talk diagnosis--What is your set doing

or not doing?? Is it dead?==No "on"?? If there is no bad fuse,the

most common solution is a bad capacitor in the power circuitry

number sequence==900's. Ex..C953    value== 1000mf/35v.

Other caps in power supply may be weak.

2) Check Horiz output transistor---shorted? Look for blown B+

fuse + weak or open C523 1mf/160v in horiz drive circuit.Replace

horiz out with high-quality OEM transistor only.I use JVC only

on 32" size & bigger ( you have 36" ).

  Let me know by rating this solution...thanks...T.

Need value for part R14109

R14109=750ohms 5% 1/4w (Resistor(750r5%.25W/R14109/179317) There is much more likely wrong with the TV. Resistor don't normally burn out with help, say, without a failing flyback transformer and possibly taking a transistor or two with it. If you need the manual, go to and type in "F31317" into the search field, you will several listings. If you decide to replace it yourself, here's some more part numbers in case you need them. Model: RCA\F25422TX41 Symptom: Dead Necessary parts: Transistor(Q14401) Main Voltage regulator Q14101 Resistor R14109 open. Research indicated the flyback transformer most probably bad \\CTC203AC4\HOT/D2578(Q14101/242224)* Flyback(14536119A/T14401/244229)* Main reg(P9NBSO/Q14101/244223) \Reg(MPS8599/Q14102/147665) Resistor(750r5%.25W/R14109/179317) Reg(MPSA06/Q14103/232218) Hope this helps you.

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.

Fuse keeps blowing

NEVER EVER replace a fuse and think that va fuse will blow all by itself. The fuses are there to protect the set from catching on fire incase theres a short inside the set. Now in some cases an intermittant short can work after you replace the fuse but if its burnt black or brownish, theres a short inside the set in one of the circuits. always use a 100 watt light bulb across a blown fuse if your not sure if there is a short. if there is, the light will absorb the short and glow bright. if there is no short the bulb will glow bright , then go down very dim. you could have a main power supply problem, such as shorted bridge rectifyers,shorted main b+ capacitor, Hot could be shorted, or the Vertical or audio output IC could be shorted
