Hello sgaffar,

This may mean that you audio detector/amplifier IC in the TV was rendered defective by an electrical surge. Now I would check to see if the circuit was getting and sound from the audio detector (which might be in the IC also). After checking to make sure the bias circuits are ok I would suggest replacing the IC.

You will need a schematic, a multimeter, and if possible an oscilloscope to troubleshoot this problem.

I hope this helps,

Thank you,

Have a JVC LT-32DM22 Television. The power went off due to a storm. Power is back on, TV has power-red light is on, but TV will not come on. Please Help-Thanks

The power light is ON, means, the power regulator board is working properly. You have to troubleshoot the main board. If you're sound in electronics, and wish to get more details, check this link. Selecting the view option, either to Mosaic / Flip card, can be selected by the drop-down list, by the top left of the display window, will make surf easy. You can also do a search, by type in the brand name / model number / IC used, in the search box at the top right of the display window.

My Mitsubishi CS-2610 S-Monitor suddenly blacked out! I am having a difficult time finding a job, and cannot replace my TV right away. Can it be fixed?

tried to re soldered first cold soldered component parts at the main board which may get loose contact. if can not get with re soldered check bulged or leak capacitor at the vertical section. and then try to observed if the vertical ic is too hot, that was mean the ic get bad.just replaced with new one and re check other component near the ic.

Tv will not turn on

This sounds like it might be a main board issue. Depending on the television brand there are different replacements you can get at different prices. I would try unplugging the tv from the wall first then try plugging it back in while holding channel up/volume up on the tv as you are plugging it back into the wall. If this doesn't change anything it is most likely a problem with your main board.

On_Off light blinks three times but power will not come on.

Your tVs horizontal output and oscillator has some trouble with it. When the power supply gets ON, the horizontal frequency that drives the horzontal output section won't generate the horizontal frequency, that output section wont' work, the main system control microcomputer IC will sense this situation, and give shut off signal to the power supply. That is happening now with your tV.
A through checking on the main board should be done to detect this fault. you must have sound knowledge in electronics, how the TV works. Also must have all testing equipments with you including a high quality digital multimeter. Normally this fault occurs due the main chorma-video jungle IC. But before replacing it, you have to check all other components in it. Some loose soldering contacts may also make this problem.
If you have the ability and skill, Inform me. I'll assist you. OK.

Tv got a straight horizontal line

A straight horizontal line across the center of the screen denotes the full failure of vartical sweep in your tv. There is two main reasons for this. The first one is vertical output Ic and any of its related parts inside the printed circuit board of your tv is faulty. The second one is deflection yoke [the coil fitted alongwith at the neck of the picture tube] is open. The second fault said here is very rare. The fist one is reported more.
There may be, as said earlier, the IC [Integrated Circuit], may be faulty. You just locate the vertical output Ic inside your TV. normally in most televisions, it will be screwed into a heatsink metal, as it will be get heated during operation, the metal conducts the heat gereated by this Ic to the surroundings, to make it at a constant safe temperature. In most cases, we have seen, this Ic may opend. That is its inside drive integrations got faulty. It has a particular number marked on it. You must note that number and replace it with a similar type and number.
You just open the back cover of your tv, while it has been isolated from the mains supply, by unpluging it from the wall socket. There are four wires run to the deflection yoke (stated earlier), amoung, two of them will be thicker than the other two. Catch up the other two thinner wires, and look from where it is connected to the main board. You can see very near to this connection, an Ic fitted into a heat sink screwed. That is the Ic in suspect.
With set open, supply it and wait for 5 minutes or so, and unplug the tv from wall socket, and touch the heatsink of that ic gently, and see whether it overheats or not. Some amount of heat will be there, but it should not be overheated. If overheat is there, the Ic has damaged. Replacing it is the only remedy.
Another possibility is, the said Ic doesn't get the proper supply voltage to it to work. To find this, you should have a multimeter in hand, and the ability to find out the points I am going to report. Refer to the schematic diagram of your TV [not the manual, It gan be get from electronic book shops], and find out the main supply point of that Ic. It is a hot check, that is you only can check it with your tvs printed circut board pulled out, and the tv is switched on. Every precaution against electric shock shuld be taken before that. Keep children away from you, and let an adult beside you.
If the main supply voltage is correct, it may be around 35VDC or so, check the voltage of its output pin. It should be neare to 1/2 of the main voltage. If ther is exess votage shown, or no voltage at all, surely the said Ic is faulty. Replacing it will solve the problem.
Find any difficulty, report it to Fixya. They will give alert yo me. Ok.

No sound black screen

You can see the Vertical Outpu IC(must be damage and resistor from the flyback tranformer), but check the main power supply STR. Some times this STR not seems damage when you test out of main board, but with voltage it funtion not well.(Sorry my English).
