Tv is about 4 years old. Suddenly developed two


Your plasma screen is made up of 1080 verticle lines and now a few of these lines are not working. This is the screen itself and needs replacing.

Picture has white horizonal line accross it


You have a vertical collapse. Not sure if its worth fixing because i don't know what type of set it is or how old. But vertical is not usually expensive to fix. Possibly just replace vertical ic

HORIZONAL LINES


that is because you have a defective vertical deflection circuit, check all the caps and if that does not solve the problem replace the vertical output ic

good luck

31'sanyo tv analog has a white horizonal line thru it


There is a failure in the vertical amp section. This can be the main output IC, or any of the support components in this area.

An experienced tech can troubleshoot the set, and determine and service the fault.

No Picture Has a bright horizontal line with off white & gray vertical bars


The Problem Philips 27TS54 c101 27B800-7562 White horizontal line in the center of the screen. Color is present in the first half inch of the leftist corner of the horizontal line.
Audio is present and controllable. The green power led from a cold non plugged in state remains solid until CRT goes to ignite. A click is heard then the green power LED blinks.
I found service manual diagram of repair part or parts and install instructions

Possible Answer Posted by PEE_WEE 4/28/2005
On the CRT circuit board(picture tube), you will find R3340, which is a 10 ohm 1/3w resistor. The location of the resistor is printed on the bottom of the ckt board. It is burned open, replace with a 10 ohm 1/2w resistor. This will solve your problem. The original resistor was sized too small, should have been a 1/2 watt. This resistor is mounted standing up on ends. Mount the replacement resistor the same way. Be careful and don't get the circuit trace too hot and damage the circuit trace. (it's very small) The resistor is located on the crt(cathode ray tube), pcb(printed circuit board) socket. The resistor supplies apx +200v to the collectors of the r, g, b, video driver transistors. If this voltage is low, it causes excess brightness(excess beam current), causing the set to "shut-down". If the shut-down is too quick, you will NOT see the excess brightness, because the picture tube has not warmed-up enough to display anything on the picture tube. To see if the set displays "excess brightness", you will need to turn the set "on" about 5 to 10 times. This will heat the picture tube enough to display "excess brightness", IF that is the PROBLEM. Of course, there are OTHER defects that will cause a tv to shut down. There are built in safety circuits, that will "activate" if excess voltage/current or heat is detected anywhere in the set.

NOTE
My resistors are not numbered the same on my crt board APT187. GSM 02/20/2008

T.V. has no picture


I noticed a bright horizonal line about 1/4 in.wide centered in the middle running from side to side. Audio is fine. This just all of a sudden happened it was not gradual. it is due to vertical section failure. please minimise bright to protect crt. solution. solution 1 check supply to vertical section. 2 check for ic failure in vertical section 3 check vertical output section parts. Is it fixable or dumpable?? Please HELP!!!! yes it is fixable it is common problem not major one. good luck.
