How do I find the power board in a 1997 big screen Sony TV to check the fuse? How do I check the fuse? I live in a house built in the 1890's, and last year there were 2 different tornados ,within 2 weeks of each other, that blew over trees on top of my power line twice in 1 month. My TV hasn't turned on since then. Is it the fuse I need to be checking? Should I replace the power cord, maybe just the cord is fried? It

clicking noise inside, screen comes on and goes off. No picture.
checked voltage on pin 10 get 5 volts connector cn804-1.
research on internet seems to point at main power board, but some think its standby power board.

After reading several forums when my LG 42PC3D died, I went in thinking I had the answer. It would turn on, but then off immediately. The Y-sus board had a blown fuse. I didn't want to risk frying anything else, so I replaced the board rather than just replacing the fuse. When I disconnected the board, it would turn on and stay on. Now, with the new board, it powers up as soon as I plug it in (doesn't actually turn on, just powers up) but won't do anything. The screen is backlit with just

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 replaced the STK chips and one pico fuse that was blown on the input power board (the fuses and resistors near the STK chips are fine). I turn the power on, no screen and I get sound for 1 second, then it turns itself off. The power LED blinks 4 times, long pause then repeats. What should I look at next.
A blink of 4 times is an error code that there is no vertical deflection. There may still be a problem with the + or - 15 volt supplies. This error is generate when the vertical deflection pulse is missing. there might be a problem with ic 8003 ...

DP46849 Sanyo. I have checked all of fixya for solutions. I hane no sound or screen but have a green light when turned on. It will flash as if it is in protect mode. I have checked voltage and there seems to be 5v, 12v and 15v as indicated on power supply. I cannot find a 24v to read from but I did pull the master inverter to see if I had sound. Still the green light flashes and no sound. I suspect power supply only because when it is turned off I hear a high pitched whistle that slowly goes on

I have a Magnavox 20MF251W/37 that when I plug it in it turns on to the standby mode (red power light). When I power it on with remote or by pressing power button it does turn on (blue power light). Shortly thereafter, I do see an image (snow at this point since I don't have it plugged to any video source). However, that image stays on the screen for only 1 second then disappears. The unit is staying on and is NOT going back into standby mode (power lights stays blue). I have replaced main

My TV is showing convergence symptoms: the screen looks like 3D effects and as if someone is pusing in the middle of the screen.
I've replaced my STK's, 2 pico fuses on the G board, and tested each convergence resistor along with the pico fuses on the D board--albeit they were still soldered in place. I desoldered two pico fuses and one resistor to test them in said manner, but they checked out fine. I've gone over every square millimeter around the soldered area of each STK with a microsco

I have a Sharp LS-26SB24U that has a white screen when turned on. I tested main fuse and F404 fuse both were good. I tested power going from F404 to ground and it was 13v on both sides. I guess my next step is to see if the T-con board is getting power but I'm not sure how. I tried following a white line that said power and along is was a hole and I went from there to ground but got nothing. Any help would be greatly appreciated.

I have a sharp lc-42SB45UT flat screen that after a thunderstorm will not turn on any more. Now I am pretty tech savy, and here's what I've done. Checked cable and receptacle and both are good. Taken off back cover and checked fuse, also good. The voltages on the power card seem correct by my multimeter so power is being applied, but the power on led is not lit. Any suggestions?
You are on the right track--follow the voltages--set has a standby power supply--right at or part of main supply---runs 7/24 so likely was damaged.likely you will find a open somewhere between where power AC enters set and the bridge rectifie ...

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. The LED should flash a certain number of times a short pause and another series of blinks. ...

The blue power light was on though and I could turn it on and off with the remote but still no screen. I tried unplugging it and plugging it back in but nothing changed. I checked the back and there is a red blinking light.
