SOURCE: tv dead

no problem

replace by same number.

but remember before you replace check the following.

  1. check for normal output from power supply.
  2. check components connected to flyback transformer.like capacitors & diodes.
  3. check for print short.
  4. while replacing h/output be careful to check heat sink compound & mica sheet normal.
  5. put on the set
  6. if still it blows then flyback transformer is faulty.
  7. hope this will help.
  8. good luck.

I would check your caps first, but usually the power supply is bad when things don't power up.
Good luck

SOURCE: Horizontal output transistor failure

check b+ comming from p/s. also check for blue flat caps in line with h-output circuit. if blown out the side. remove them from circuit. also might have a HVT goin bad. I believe this is also the model that might have a mod for h-out running too hott that requires adding a resister in the h-drive circuit. also try a heavier duty h-output.

I have a 55 inch JVC tv,today the screen went black but still have sound, also the buttons on the back wont work, but the channel down button turns it on and off? What is wrong with it?


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary..

Sony trinitron KV-32S26 While watching the tv it went POP and the picture went pop. Is the picture tube shot?


not really..maybe an overloading of the secondary power supply could create this problem..check first the horizontal stage circuit for shorted component..before suspecting the picture tube

No sound JVC tv Model # AV48P575


You will have to use the control buttons on the front and navigate to personal pref. and restore that to normal. You may have to re do the initial set up. Be patient and give a whirl. Let me know......

Tv shutting off timer light blinking


Your TV is in the protection mode. First, locate the horizontal output transistor. This is found very close to, or next to, the horizontal output transformer (also known as the flyback). The flyback should be on an aluminum heat sink, or on the side of the metal chassis. Disconnect or unsolder two of the three legs of the transistor. Measure it with your meter, or plug in the set with the light bulb attached across the fuse.
If the transistor is shorted, or the light bulb doesn’t glow bright anymore, replace the transistor and plug back in. If the light bulb glows bright again, you must replace both the flyback and horizontal output transistor simultaneously. In some cases this will fix the set, but sometimes there are multiple problems with a set.
Go to where the flyback is, and start measuring the diodes and capacitors on the flyback itself. If you don't find any shorts there, it could be a shorted vertical output IC, a shorted sound IC, a shorted disc capacitor in the Hi Voltage/sweep circuit, or in rare cases, a shorted capacitor or tuner.Feel free to ask and post whatever the result of your troubleshooting..


Hope this may help;

You need to check the horizontal output transistor first for a short,ift he transistor is good check the diodes and low value resistors of the secondary of the flyback(output trasformer),if all those are ok check the crt board,it has low value resistor for the g2 voltage,if ok you need to go back to power supply and check for a short from each one of the diodes to ground for a posiblwe short.Be careful when measuring voltages and use the correct ground.

Horizontal Lines


The unit most likely has a short in the horizontal section and would require repair by a service center. Go here to find a JVC repair center in your area http://maps.jvc.com/cAscList/
