Hi. I have an LG 47LB9DF-UA LCD TV with a video problem. Originally, I had problem with horizontal lines, accompanied with a lag. After a short time the screen would then get multi-colored vertical lines. If I turned the tv off, then back on, the lines would be gone. If I left it on, the process would start over again. I opened the tv and found two connectors from the power supply board to the main board loose. After removing then reconnecting them several times, the problem cleared up. I l

Problem with TH-C50FD18:Gives off 2 blinks I replaced the D-board and the A-board to no avail. The power trips the moment the 15Volts ON occurs to send 15volt power to SS, D-board, A-board and SC-board. I found no short on this 15Volts line that is switched by the MC701 Power MICOM Processor. It looks like a 15Volt error is detected, nonetheless.That's why it always reverts to standby mode. Could this be a 15volts power regulation problem?

Samsung ln40a530 Hello, I repaired the power supply on that TV. I changed four capacitor 10v 1000UF and 25v 1000UF and a small chip on the pcb QM806 (4894B: SI4894BDY equivalent) Now I have a good read on all output. Thank you for the help found here! But now I found a ground on the main board. 5volt is on the ground(short). I unsoldered some chip without result, the 5v is still on the ground. Could someone tell me what the problem might be?

Hi, I bought a Vizio L32 HDTV10A that didn't power-up. There were charred components on the power board (an 8-pin IC with heatsink and 2 resistors). I replaced the power board, and the power LED then turned on (yellow) when power was applied. When the ON button is pressed, the power LED turns green for roughly 8 seconds and then the power LED turns yellow again. Nothing else happens. I checked many components (fuses, capacitor ESR, diodes, etc) on the main board and the master and slave inver

I have a WS-65611 that I have replaced the caps on the DM board. Before I did that, the power LED flashed non stop, Now it does the normal 70 seconds but when I attempt to turn it on, it shuts right back off. After attempting a power up I checked the error code I got a short protect error. I then removed the DM again and verified the caps were not shorted to the shield and checked the pico fuse and found everything to be good. Any ideas of where I should start looking??


Did you run the error code operational check? In not unplug the set and plug it back in. Press and hold the DEVICE and MENU buttons for 5 seconds and release.

I have a LT37HVS Olevia flat-screen that has a similar problem to one of the posts. I had the same blue standby type light on the front that stays lit, but turning it on just makes this light blink, and no display. I did as the posts here sugested, peeled it apart and manually inspected all of the capacitors. To my dismay I haven't seen one yet that looks bloated or leaky. I have inspected the main power supply board, both display boards and the main board. There were a few capacitors that

I have a LG37LF65 LCD TV. Several month ago it broke down, at that time power supply was repaired. After a while after switching it on picture started to shake and then totally disintegrated. I have taken it back to service they said this is main board failure but since I cannot find proper board. Is It sure that is main board fault or can it be anyithing else? Can I check anything to be sure?


Check the power supply voltages to make sure you don't have another capacitor going out (the first one replaced is probably OK). Poor filtering on a supply voltage could cause the main board to misbehave. If the voltages are good, the shop tech is ve ... Flat Panel Televisions
