TV Sound Regulator ICS International Control Systems

How can I can't make the sound regulator work on my tv.

  • Pat Luke Mar 28, 2008

    I purchased a tv sound regulator over the internet for my tv which was supposed to control the changes in sound volume especially when commercials came on. In my case, it is supposed to be hooked between satellite dish box and the tv. After setting it up according to the instruction manual I still get no sound or video. I have an RCA tv model F19421 and a direct tv satellite dish box D11-300. Any and all advise would be greatly appreciated!

Proscan flat screen went black and no sound

The power supply regulator section of your tV has the fault. The set need service. Contact any experienced service technician, as it will be dangerous for an unexpereinced person to work with the power supply regulator circuits.

My television has a blue screen and the red light at the front of the television keeps flashing,how do i get it to work?

Your telivision may have its Chroma Ic faulty. Sony TVs uses their own coded numberd Ics, usually begin wi CX xxxxxx, or Philps TDA series Ics. These Ics contains so many sections integrated to one. That is Horixontal, Vertical, Synchronisation for both horizontal and vertical, video out drive section and its matrix, video If section, sound filtering section and so on which comes over 68 sections or so.If any of the among said section gets faulty, your tv will have some problems.
Here you can see a Blue screen. Therefore video out section of your TVs Ic is working well. The red flashing LED in the front of your tv indicates that there is some kind of short, not direct short, inside your TV.
You just do one thing. Open the back cover of your TV and find out the IC I have mentioned above. Switch on your tv, wait for 5 minutes or so, switch it off, unplug it from mains, and touch on the surface of the said Ic with your bare fingers and find whether it is overheats or not. Such types of Ics can be heated upto60 to 65 degree C. Not much more. If that Ic is faulty, it will heat up to a condition, which you can feel.
If there is no overheating is noted, there may be some low voltage missing. Sony TVs works on 112vDC main rail, 8VDC secondary rail, 5VDC for system control section, and 24VDC and 18VDC for vertical output and sound output sections.
Normally we noted is the missing of 8VDC rail. This 8VDC is derived from the secondory voltage of LOT, through a stepdown *V regulator Ic. If that Ics soldering point gets loose conatcted, of that Ic itsef is faulty, This kind of fault can occur.
If you are going to do it by yourself, keep the children away, and let an adult beside you as a precautionary measure. Never touch any part inside your tv while power supply is on. Take out power plug from the socket before touching any parts.
As yours' is a 27" TV, at about 25KVDC [25,0000VDC] points will be there inside. Keep Caution. Ok

My tv turns on color works, sound works, then about 45 seconds after it is on, it dims out and shuts off

Your TV has an internal voltage regulation trouble. Set switches on, finds some voltage troube, normally overvoltage and shuts down. Your TV has an internal voltage regulator. Check if its secondary voltage is more than 110VDC on load. It can be vary from 105V to 115VDC. If it higher than 115v or so, your TVs system control Ic will sense it and shuts the whole supply voltages to down. It is a protection done by the manufacturer. You just check it. In most televisions there will be a preset onboard control to adjust it. For that you need the proper measuring equipments and some skill and more patience.

I can't get any power? What is wrong? I tried with the remote and also using the buttons on the tv...still no power.

Hello cwcritters, hi, does your tv front panel has any pilot light on or nay sign that the TV is on, if yes, there is problem with the main board and power supply, probably a short, this TV is on standby, here are the things to check, a shorted horizontal output transistor, a bad voltage regulator, or any ICs that are overheating, NOW if there is no light at all, then your TV may have fuse open. A fuse opens when a user plugs the TV while the power switch is on, causing a surge of electric current. or TV develops a shorted regulator. If you dont know anything about electronics, dont do the service yourself, you may further damage the TV, better call service.

check the horizontal output transistor for short. if so then check main regulator ICs for short and white .1ohm resistor for open. also check horizontal transformer for cracked solder as this is the cause for failure

Tv won't turn on

Most likly it is a problem in the power supply regulator circuit. pretty common for Toshiba TV sets. If you know about TV serviceing, first thing to replace would be the regulator IC as that is the problem 80% of the time. if that does not help then you will need a schematic to trace out the regulator circuit. Good Luck PS please dont forget to rate this thread.
