SOURCE: Speakers have died?

Probaby the stereo decoder IC went bad or a supply voltage to it is too low or noisy. If it has audio output jacks on the back of the TV, connect it to an external amplifier and see what that sounds like. If it is ok in stereo or mono mode then the amplifier in the TV is bad. This will prove that the stereo decoder is ok.

SOURCE: Samsung DLP loud vibrating noise

The color wheel is the most common problem in DLPs that cause noise. To determine the cause: Turn the set off. If the noise goes away after about five seconds, then, the problem is the color wheel. If the noise goes away one to two minutes after shut off, then, the problem is a fan. You can find an Authorized Servicer in your area that can tell you the price of repair, by clicking on the Samsung link: http://www.samsung.com/Support/ServiceLocations/index.htm

SOURCE: Loud pop - no picture

Your X and Y circuit boards are bad. It might require the replacement of the power supply as well. This is not uncommon for LG/Zenith plasmas to have this issue. Not a do it yourself repair.

SOURCE: No picture and No sound

I have the same problem here with my Philips 30PF9946/37

I'm not sure this can be diagnosed as an inverter failure, unless there is a another inverter board in there I'm not aware of. The only inverter I found (actually two) in this unit is the pair of KLS300A1 inverters which drive the CCFL tubes.

Since I personally get a green power and light AND the CCFL backlight comes on, it seems unlikely that the inverters have failed.

Would love to hear from anyone who can ident the failure in these units - there's certainly a LOT of these around that have failed in exactly the same way.

Sound goes off to a screeching noise


The sound board is usually part of the main logic board that contains logic, sound processor/amplifiers, tuner, source selctors. Not cheap.
But you should try hooking up a set of powered PC speakers to the Audio line out RCA (Red and White) jacks on the back of the TV to see if you get the sound OK there first, if you do then the power amps that drive the speakers may be bad or it may not be getting the DC voltage feeding it. If it works with RCA jacks, then just keep on using it that way, you may want to set the audio line out to be 'VARIABLE' in the sound set up so you can use the TV remote to control how loud the audio signal feeding the powered PC speakers to be.

98 gs300 loud screeching noise that last for about 5-10 seconds


The only four rotating items under the hood are
engine
power steering pump
A/C compressor
and smog emission pump.
==== I would check the fluid level on the power steering first. Check for pink fluid leak on the ground,
==== Check the A/C system with the wheel turn to one side and APPLY ALL LOADS.
Example: high beam on,A/C max,radio on and deforster on.
This will give you system a stress test.
All eyes on the pully and locate to part that generate the loud screeching noise.
My bet is on the power steering pump.

Please post more info on the comment window.
I will follow up on it.

Loud noise from tv


if this is a very annoying screeching or sqeualing type sound, it is, in my experience, the "color wheel" which is located inside the lite engine. this is a replaceable component whick costs about $110....i've done this repair many times with no problem....
