Question about Televison & Video

Open Question

My Techwood (43AO4USB) TV flickers with static and alternates between black, red, green and blue.

This happens for about 30 seconds and then the tv goes back to normal and then it may happen in another 10 minutes?

SOURCE: TV Picture Goes Black

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions

You have a chip that is overheating due to heatsink coumpound being dried up. You need to find that chip and heatsink and apply new compound to both parts.

Hello,

Your power supply board is dead, u know basic electronics’ and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
hope this helps...

SOURCE: model hln617w. the picture on the screen freezes

Most likely your problem is on the DMD Assy Board P/N BP96-00249A . More presicely there is a few bad electronic components on that board that are bad. That board can be repaired by replacing the bad components (and the other few compoonents that are probly going bad and will soon cause your tv to lockup and lose remote and button functions when it fails so you will need to unplug it to get it on again).
Or the DMD board can be replaced .But it is not a cheap board.
For removal and Installation of the DMD board I would reccomend a tv service person because it is in the heart of the television and there are some adjustements to be made when the new board is installed.
To get the new board you could probably find it by just gooogling the part number.
Component level repair would require some experience in desoldering and soldering SMT,SMD , and or surface mount components.The actual components are about $15.00 total so just repairing your board should cost about $125.00 by a qualified servicer (if you were to remove and install it yourself). This DMD board is used in many models and can a few common problems.
HLM437W HLM4365W HLM5065W HLM507W HLM617W HLN437W HLN4365W HLN467W HLN507W HLN50665W HLN567W HLN617W ( L2 and L5 chassis )
SYMPTOMS:
-Intermittant picture freezing with a negative looking B/W frozen picture.
-Intermittant loss of pic with/without shutdown,abnormal color wheel noise if attempted to start after shutdown.
-lockup of tv control functions . Remote and front keypad do nothing , TV must be unplugged to reset .
-horizantal tearing, distortion , flippnig , solarization , red picture, leading to blank screen and lockup.(tv menu would be affected by all picture defects).
Hope this helps someone..

TV lost some of the colors


quick simple solution that might fix it. Completely unplug the tv from the electricity for about 30 seconds. Some times especially during brown outs or black outs, the processor gets scrambled and needs to be reset. This 30 seconds of no electricity usually allows the system to reset it self correctly.

Sound problem


Go into your TV settings and change the Automatic Volume Control Sound Mode. It's probably at Dynamic and the TV is trying to adjust the volume. The popping sound may be caused by static electricity building up on the circuits of your TV or cable.

Does this also happen when you are watching a video/DVD?
