I have a Samsung Plasma TV (SPS4243X/XAA). When I turn the TV on, the picture fades to black after about 1 minute. I can turn the TV off and back on and it fades after about 5 seconds. What is wrong?


Fault to its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

I have a 42 inch Hitachi plasma tv that is making a very loud static noice coming from the internal speakers. It stays at a contstant very loud volume unless I completly mute the tv or turn the volum


Based on what you have tried if a buzz or loud static via the speakers you have something wrong in the audio output circuit of the set--problem here is that circuit may be part of the Main board that processes all signal---a look inside---following the speaker leads back would lead you to that board.

A simple thing to do to narrow it a little (you may have done this) is with sound all the way off put your ear to the internal speaker--hear anything at all like a deep hum?

Depending on age of set and cost of the board likely bad it may or may not be a do it yourself repair.

No sound


Well first of all, is it hooked up properly?

I had a viewsonic which had both speakers and a mike. So you need to connect 3 things:
1) The vieo siganl,
2) The (usually) green ouput from your PC sound card ouput to the minitor speaker input,
3) The (usually) pink cord from the monitor's mike-out to your sound card mike input.

Then, next, there are controls on the Viewsonic, one is a mute function. Turn off the mute and crank the output level all the way up, those little speakers do not have much punch to them.

Finally, you need to go to your sound card's control panel, and turn up the volume to the speakers, and of course, turn off the mute.

Another thing you may want to do is test your sound card outputs with a real pair of speakers... (Surely someone will loan you a pair for a minute -- ordinary CD player speakers would do.)

Good Luck!

GE 32GT740 32" TV problem


there are two things that can cause this, 1 there is a muting transistor on the bottom of the PCB that is a surface mount transistor that goes short. this is the channel mute transistor. when you change channels it is designed to mute the static between channel changes. if it shorts then it mutes. 2 the EE-PROM is defective and needs to be replaced. i'de go with the transistor first. if you are unequipped to do this repair have a tech do it.
