Re: no audio

Is This The Hitachi GX01B? You probaly have a capacitor or transistor not within tolerance in your audio circuit. If you would like a service manual and unlimited support for your set to help diagnose it. You can go to the following link they have the46GX01B which is the same chassis as the 43, for 10.99 and they offer free unlimited support with purchase of manual. then if you go back to the site and click on the contact us link and provide your email address they will email your manual to you instead of mailing it. They will also email instructions on how to enter into the free chat sessions. Heres the link. I am one of their support techs.

Rca p61927 no sound with tv remote nor volume button on tv

First you have to check that the button-internal external speakers are in the right place, that's in the back of the TV. If there is still the problem, the audio output is faulty. Need to change audio IC. Perhaps you need technical assistance, that is a bit difficult to change IC. If you have further questions, do not hesitate I'm here to help. thanks

The red convergence on the right half of my screen is way off and will not change. any suggestions?

I would replace the Convergence IC's. They should be STK-392-110's. It should cure the problem.
They are typically mounted to heavy duty Heat Sinks and located generally on the Video Board. You should replace both of the IC's as a pair. I would also make sure you use Heat Sink Compound on the back of the new IC's when remounting them.
I hope this helps,

I purchased the convergence chips for Samsung PCL5415RX/XAA TV. Do I need to remove the entire sub deflection board to R&R them?

Yes, however I would be surprised if changing the two Ics will repair the set, as that chassis should always have the sub-deflection board replaced since most of the resistors will be stressed. Thats why samsung changed the later chassis's by removing the convergence circuits from the deflection board as its almost 98% certain that the deflection board will need replacement when the ICs fail with those chassis designs unless every component in the convergence circuit is replaced which will cost more than the deflection boards do. But you may get lucky but if the ICs dont cure the problem you will need a new deflection board

My JVC AV-56WP74 is having double vision problems. I tried going threw the convergence screen but its not working on lining it up. On top of that my TV has no sound. Its not on mute im not sure if the...

JVC's have been known to develope audio problems if the Convergence ICs short considerably as often you can get a popping through the speakers or in rare cases no audio at all. I would install a convergence repair kit and see if that cures both problems. Your model uses the AV48WP74 - 65WP74 convergence repair kit. has the repair kit and it also contains the CD with detailed repair instructions for your model.

Volume problem with static sound

Call a good TV Tech and have him replace the Audio Amplifier IC on the board. This should cure the problem.

Audio is fine, but video will off after 5min ON time

Good Day, howac506;

The most common problem for your 1991 TV is the vertical out put IC (IC) part number 272p239040.

I hope this was helpful.
Good Luck again, big IRISH.

Hi - and thanks in advance - first time here - have Panasonic model CT-2769SW - audio is either happening (coming thru or mute) or not - inconsistent - any ideas ? Mike :)

Could possibly be a defective audio output IC. I would try re-soldering it first though as that often will cure an intermittant audio problem.

Hi i have a 93 Mitsubishi model# ck35402. I was told that the pip had went out. was hoping someone could walk me through on how to remove and reroute

From the bottom of the main board locate IC 2004 between the PIP module and the tuner. Remove the jumper between pins 2 & 6, then jump pins 6 & 7. Next , pull the pip module from its socket and toss it. The symptom for a bad PIP module could be black screen, no picture, blue streaks, wavy or jittering picture.The audio will not be affected. Make sure the symptom fits the cure before you bypass the PIP. Good luck!

resolder the vertical IC that is whats making the CRTs go blank. Its a safety issue where the CRTs blank when there is no vertical deflection. Just resolder the output IC that should cure your problem

Toshiba 43HX70 convergence fix - now no video

I think the hardest to solve problems are those I installed!!
Where do we start==no lecture,but I never change a resistor
unless it has changed (in value!) Use a digital meter and check
the value of each resistor.Toshiba is a bit confusing as to values
of each resistor and location in relation to the IC's.Go over your own work first.Check micro fuses in power supply=F851,F852,
etc. Carefully resolder steel jumper wires at board edge,they feed
B+ to convergence amp circuit.Be sure to verify no shorts in pins
of IC's.(use your meter).........T
