SOURCE: sony 42 in. lcd projection tv went out; just makes a sound.

Hello,

The TV should "blink" a number of times after it fails to start up (the red light blinks a certain number, pauses, blinks a certain number, pauses, etc.). This tell what is wrong with the TV. If the LAMP light is what is blinking, then the lamp needs to be replaced.

Most of the problems with this television are related to the lamp or lamp chamber. If the Television lamp is burned out or worn, or the lamp will not start, then it will not try to come on. There are circumstances where the LAMP light on the front of the TV will not come on, even though the lamp is out. I would try replacing the lamp (which is meant to be user-replaceable). The popping noise you heard could have been the lamp going out.

The lamp chamber door also activates a switch that tells the TV that the door is in place. This switch will sometimes go bad, showing a relatively small amount of resistance, but enough to fool the TV into thinking that the door has not been replaced, causing the TV to shutdown. Make sure that the lamp door is properly replaced if you do remove it. It is no longer available from Sony (too many warped doors from heat damage).

Lamp part number is available in the user manual, as well as instruction on changing it.

Hope this helps you...

Your tv is being attacked by electrical surges which seem very violent and has already damaged some logic controls. Please invest in a AC filter which will protect your tv from such spikes....... but first you need to get your tv serviced from the electrical damaged it has already suffered.

SOURCE: tv is flickering non stop and a has a low popping sound

Hi,

Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps

SOURCE: my dynex 32" lcd tv picture went out but sound

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.

Rear audio jacks


Try pressing the mute button on the remote control. This control will normally allow you isolate the sound to only the headphone jacks. It may be that it was pushed accidentally and was left that way. If this does not solve your problem you can call the Dynex customer support at this telephone number 1-800-305-2204 between the hours of 7am-12am CST. You can also visit their website at this web address.(http://www.dynexproducts.com/pc-680-23-dynex-32-720p-flat-panel-lcd-hdtv-matte-black.aspx) Just copy the address and paste it into the address bar on your browser. This will take you to the customer support page for you model television and you can use the e-mail function to contact the customer support directly. I hope this information helps you with your problem.
