Bad components in the horizontial/vertical output. High voltage (flyback), even a bad relay or weak component. These 'steady' failures are often thermal problems as some components fail, they work when cold, turn them on, they heat up, they fail, they cool off, they work. You can pinpoint with some cold spray. When it fails hit the chip or component you suspect with the spray, if it comes right back. Thats your circuit.

I have a 42PFP5332 which doesn't turn on. When plugging in the power the green led on the power circuit board turn for a few seconds and then blinks for 9 times. After that it blinks for 10 times


Good day!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

Red light blinking and no picture on Toshiba Model 65HX81 how do we fix?


Red power light blinking is shutdown--protective mode.

Before buying a remote I would see what is wrong with set.

The most common reason on this model is a short in the convergence circuit--uses two chips----method to see if they are shorted is to locate (not real easy on this model) and unsolder all 18 pins on each chip--if set turns on then(will look bad) one of the chips is gone and both need replacement.

The other issue this set has is bad Hyper boards that cause noise when cold and operate after warmup---more expensive to fix than a convergence problem.

Kp-fx532m91 green blinking and followed by red blinks


10 blinks is a high voltage protection. This is why it has a retrace lines on the picture. It can't be fixed by reset or unplugging the set from the outlet because there's a faulty parts inside. It needs to troubleshoot the deflection circuitry to determine which part(s) gone bad. You need to ask for an assistance of a qualified TV Technician because this kind of symptoms is not DIY unless you have an experienced in electronics.

Also, check if you're unit is under warranty period/extended warranty, avail it because the manufacturer will fix it for free. Opening the rear cover will void the warranty.

Have a black screen infront of my tv picture but not when I use the vcr I have a toshobia cn35f90


Turn off closed-captioning on the TV. It's gotten turned on and set to "text" mode. There's a button on the remote to control captions and it's easy to do without realizing it. Use the button to go through caption settings to turn it off and the box should be gone.

tv is drawing too much current and protection circuit kicks on and shuts tv down. try turning all screen controls all the way down. if that doesnt fix it, sounds like bad green picture tube. suggest local service center

While watching my toshiba cinema series 36'' television yesterday the screen faded out and made a popping noise for a couple seconds. The picture came back but I have no sound now. Any idea what system...


I'm going to speculate. Audio system component shorted (output), changed bias and picture faded, *POP* component failed completely, bias returned to normal, picture returned.

?Shorted resistors and/or chips in audio output circuits?

I wouldnt expect electrolytic caps to be a problem in these newer units, but you might check for open caps too.

Check your level from the power block, if you can scope your B+, check the ripple. If its bad, the PS block may have been damaged.

Take this with a grain of salt. I'm not real framiliar with these units.

Toshiba 50HX81 projection 'tv- blinking red light


The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.
