Question about Prima CV2011 TV

1 Answer

Bottom of screen flickers, and eventually the screen 'freezes'

Prima flat screen, wall mounted TV.  I get horizontal waves (and I don't mean wavy lines, but rather pulses, I guess) at the bottom of the screen.  If I leave the TV on while this is going on, the entire screen will eventually freeze with vertical lines of black and color.  It first happened while I was watching something I had PVR'd, but realized that it happens on TV too (HD or otherwise).  I made sure all the connections were good and solid, checked some settings...all seems right.  Had good viewing for 2 days, and now it is back to the waves and freezing...am I hooped?

Wavy horizontal lines across the screen


It sounds that the main power supply section to your TV has the fault. The horizontal thik lines that appears crawling down across the screen should be of video 'HUM'. Have you replaced the main filter capacitor at the power supply section? If not, replace it along with the main rectifier. The AC power is rectifed by a bridge and applied ot this main filter capcitor. It will have a capacitance value between 120 to 350MFD 450VDC. Check this section. Measure the rectifed DC voltage acorss this main filter capacitor. It should be around 350VDC, if your home power supply line is 220VAC. If it is 110AC, this DC voltage will be around 165VDC; and it should be. If rectified DC voltage found lower than the input AC voltage, replace the rectifier bridge. In some sets, this bridge section have four diodes. Some other circuits, a bridge rectifier stalk may be used.

Horizontal,wavy lines on sony xbr4 52" sony lcd tv


hi,
check the ground connection of your house wiring. fist of all remove all the external input like set top box, cable connection, dvd etc from the tv. Then power on the tv and watch is the wave is there or not. if it there then ,if the tv power cord comes with three pin connector then remove the earth connection on the wall outlet socket to which you connect its power. the connect the power and switch one the tv.
if the wave will not appear then connect external devices (set top box, dvd etc) one by one and watch which device produce this wave in the tv. also check the ground connection of that device which produce this wave.
If all these will not help full then the SMPS power supply of your tv have some problem. Normally this type of complaint arises due to the faulty Main filter capacitor. you can see it in the power supply.. It will be the big capacitor according to others. Normally There will two or more. replace the same. will solve this problem. if you need any more assistance feel free to contact me through fixya
ok

Wavy horizontal lines on bottom of RCA 36in Truflat TV


The convergance or y-sus board can become faulty. The capcitors do tend to burn out. It is about a $250 + repair for this. Not all parts can be repaired, but they can be replaced. A capacitor tester and multi-meter are about the best tools for the job. If the price you get is over $250, I simply would replace it instead of repairing it..

Wavy red lines or red pixelation, not sure what it is


Go to Vizio website and buy the extending warranty, you need to have your TV replaced since the problem is with the screen itself.

Wavy Screen on Startup


I gather from your post that wavy can mean two possible things as the TV comes on, you see the picture flow like ocean waves? In this case you may have 60Hz hum modulating with the picture, this is actually unlikely these days, but I have heard it happens sometimes. The other thing it could be is light horizontal tearing. This happens when the horizontal frequency is too high or too low. You are not going to like my solution because I feel that for problems like this the set must be analyzed not just subjected to "shotgun troubleshooting", so here I go, Take the TV to a repair shop.
