Locate audio output IC. GO to www.alldatasheet.com for the pin out. CHK for VCC, CHK on the INPUT on the ic for a small sound via an amplifierOR before forget rub your finger across ic pin to see if you hear a if you hear a sound then your problem is in the preamp stage and not the output.

My RCA T19060GY TV/VCR will not stay on. When I push the power button on the unit itself (I don't have the remote.), the green indicator light comes on for two seconds and I hear to click sounds


the clicking sound is due to the relay is getting turn on but doesn't stay because of bad component in the power supply board or in the main board. you must check first the bridge type diode and FET transistor using an analog or digital tester.

My GPX tv/dvd combo is making an intermitent 'buzzing' sound,anyone know how to fix it?


Is the sound coming from the speakers? (do you hear it with the sound turned off)

Either an audio problem if heard only with sound up or if a buzz with sound off it is a coil or transformer on the circuit board vibrating hard enough to produce the noise.

Both are fixable but require different tactics to resolve.

DVD stopped playing in middle of DVD. Stopped it, took DVD out cleaned it with soft cotton cloth,returned it it only said loading but never played. Tried several DVD's and CD's nothing happens. There is...


The clicking is the sound of the laser head being moved across the disk. Since the head is moved and the disk is turning then the laser head has developed a fault in the control of the lens . This is unfixable, the entire optical unit will have to be replaced. Luckily it's a standard PC IDE unit, that can be bought for less than $30 at all pc shops. The only complicated stuff is the replacement operation itself: you will have to dismantle the tv to do it.

I have a Toshiba TV/Combo The set will turn on then it turns of in a second. It will not stay on.


It seems that your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done. It is that sound that gives it away, this is a typical switchmode Power Supply problem.

It sounds like the High voltage transformer has gone out. If you open the back of the tv and look on the right side, you will see a large (4 - 5 inch) black cylinder with a large wire coming out of the top. without touching anything, look and see if it is cracked.

No sound


What brand? Often people accidentally turn the internal speakers off, although probably not on a combo unit. Other times folks turn the audio all the way down on their cable box or satt receiver, then there could be no or low audio for the TV reception. But dvd or vhs sources would still work. Always possible for the small speaker to blow, or audio output to fail.

Clicking sound from VCR area


there is a infra red LED inside the unit that fails. this LED sends infra red signals to 3 other sensors for load and stop and counter. when this LED fails the mechanism thinks you are loading a tape. have a tech replace this LED.
