We went to auto focus on our tv. It shook wildly the when the picture came back the picture is bent. When looking inside the tv the green and red are being projected bent at the top and bottom. Please...


You need to replace the convergence IC stk392 -110...2 resistors and a fuse. located in the deflection board of your tv and after you can press auto focus and the picture will be normal.

I have a 46" DLP TV, I have sound but no picture. But I can play a DVD, and it works fine.


Does the dvd have picture when playing or no picture no matter what?

You can try switching cables.

Do you know if the screen is on?

No picture but have sound


Hello,

If your television comes on and has no picture but sound, there is only one major cause of such problem and it is the t-con board of the television, a defective t-con board will cause your television to have sound but not picture.

Have a repairman replace the t-con board and the television will be in good condition once again.


Take care and good luck

Same problem - Picture and sound go off and on.


Yes the sound is lost when picture goes out. Found it was the power supply overheating - I cleaned it (dust caused the overheat) and it has been working for about a month but I anticipate having to replace the power supply soon.

No display or sound on Mitsubishi WD-52725


This is a DLP They have issues with the color wheel, the winding sound could be from this color wheel. If it stops spinning it will cause the tv to shut down. DLP is a mechanical display process. If you are handy and understand electronics you could replace this yourself. If not i would let a tech handle it.

No picture. Red-blue stripe across screen


there is a computer chip that is now toast on your motherboard. I don't remember the name of it but same happened on my RCA. It is caused by over heating. Over heating is caused by lousy vent design. Its important to place TV on hard surface NOT CARPET. I learned the hard way. The chip that went out is a $15 - $20 part, but finding someone to put it in for cheap is like winning the lotto. hope this helps.

Is this fixable??


Unfortunately, this sounds familiar. Many of these sony projections had bad crt's.(picture tubes). Now here is a secret I learned along the way. The short in the picture tubes is in the filament, causing that color to overpower all others and sometimes causing pix to disappear until set is shut off and back on. If you are very careful and use an insulated screwdriver, you can sometimes tap on neck of picture tube and knock debris from filament causing extended tube life. This is dangerous and must be performed with set turned on. From front of set gently tap on neck of tube(s) in question using insulated handle of screwdriver to make contact with picture tube neck. Picture will probably flash whichever color tube is contacted. Eventually, if picture stops flashing that color as much, you can sometimes get several more months out of your set without any problems. Only alternative is to try a crt rejuvinator or replace tubes at a cost of 200.00 each if avail. plus labor. Good luck, Russmann.

No picture but sound on panasonic plasma


Unplug the TV and disconnect any HDMI cables to the set. If the issue goes away there is a possibility that your HDMI source is causing the problem. Anything on the HDMI can cause odd problems with the TV since the serial data and serail clock lines are routed on HDMI. Those are the 2 commmunication lines used throught the TV for operation so anything HDMI that might load down one of those can cause issues.
