SOURCE: no sound

The speakers on these are usually at the bottom and do come off the set. If they are on the TV make sure there are wires connecting the speakers to the back of the TV at the speaker terminals.

SOURCE: i have a akai pdp4294 tv with sound and no picture

I had a similar problem with my 42 in Philips LCD HDTV.


Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.


Here are some options for you.


1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)

Remember, TVs CONTAIN HIGH VOLTAGE AND CAN KILL YOU! Do this at your own risk.

2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found online. I would definitely shop around though.


3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.


This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.


Hope this helps and if it does please rate it accordingly. Good luck.

Teac A R300 right speaker has s badly distorted sound after 20 minutes. When I turn it off nad turn it on again, Same problem after 20 minutes. Left channel working perfect.


Have you changed the speakers to see if it is a driver, or amplifier, issue? If it follows the speaker, get it reconed. If it follows the channel, look into that channel.

Akai PDP4294 has pic, but no sound.


Check the speaker/s first. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Surf the site with patience. Pull up older posts. Surf the site with patience.

No picture ; no sound


the red blinking light usually has a pattern that gives you a code to the possible problem.
Maybe you have a bad power supply board. You have to open the panel and do a few tests on the power supply's outputs to be sure.
It produces a variety of voltages for different parts of the tv ie. the plasma display panel and the audio system. The components supplying power to the audio system may have failed a year ago and recently the pdp.

plasma tv's are expensive to repair, most of the time you can get a better tv for the same price. You can reduce that cost by learning and troubleshooting it yourself.

Cordless phone, no power


Are you saying its taking a long time for the sound to come out of the speakers?? or that theres no sound at all?? If its taking a long time check the resistance of each speaker to see that a componet in the crossover or the speaker didnt short.If you take all the speakers and if theres supost to be a relay for protection and you hear it click then the amp is good or has an out put stage problem like bad poutput devices or blown driver transistors. Need alittle more info if you could Thanks.
