I have a JVC AV-56WP74 that all of the sudden has a bow screen on top and bottom with green and purple tint with double picture. I have tried to fix the problem working with the convergence troubble shooting out of the menu but still with the same problem. What part do I need to replace to fix my problem?

You need to replace both convergence ICs they are STK392-110 you may want to get the resistor kit as your model will usually have a couple open resistors.

LG LED TV has sound but no picture. Went out all of a sudden. Image shows with flashlight. Flashes for split second on power up and power down.


Your screens back light has most likely failed and or the voltage controller for the back light, both should be replaced.

Sony Bravia flat screen TV when turned on has black screen. Green light on the bottom is lite up, electric plug is plugged into house socket, no picture only black screen.


If audio is OK, the fault is with its backlight section. If audio too is absent, the fault is with its digital main board. If you wish to get more details visit the site linked here. Pull up older posts.

Black screen, green light on the bottom is on, electric plug is on house plug, no picture, was working fine last night, now only black screen!


Do a hard reset to this set, and then check. If it do not help you, check and replace its main digital board. It will be faulty.
There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

WHY DID MY VIORE SCREEN RESIZE TO SMALLER SCREEN


Screen size depends on the broadcast signals aspect ratio, the TV adjusts for that automatically, the picture can have no bands or be banded top and bottom or on both sides.

When playing commercial DVD's, my DR-MV150B starts to stall. It stops with the picture on the televsion screen, but can't see the rest of the movie. Any thoughts? The disc does eject.


Try cleaning the laser with a bud, if not it's either the spindle motor or laser assembly,
ELECTREPAIRUSA@ELECTREPAIRUSA or you can contact us at that address as we repair/renovate all items electronic and electrical old and new.

I have sound but no picture on my tv


This is a popular question. Most of the time you either need to make sure all connections are not loose or just need to turn off your tv and receiver and unplug. Wait for 1 minute then reboot.
I recommend this short video as it walks you through some diagnostics for other possible problems.
