SYLVANIA LC200SL8 WILL NOT POWER ON

No power. Fuse not blown. Anyone know what might need to be replaced on the main board?
I have tested the power section and am not getting any power on the secondary side of the power transformer. Schematic that I found on the internet does not show Primary & secondary voltages for the power transformer. Anyone know what they should be?
Also, I took the board out of my Emerson LC200EM8 and connected it to the Sylvania LC200SL8 LCD screen and the screen and back light work, but there is a blue, line from top to bottom near the left side of the screen. I am not too worried about the blue line. I think I can correct that once I can get the main board to power up.

SOURCE: Sylvania 6632 LG blows fuse when plugged in

I too had this problem. I read some posts on this site about how to repair it, and low behold, they worked! I took the back off of the TV, and the first thing I found was the fuse was blown. With my meter, I checked the first 1N5406 rectifier diode after the fuse, and found that it had shorted out. Then I had to learn to desolder the diode, which I learned about on Youtube. I bought a pair replacement diodes at Radioshack for $1.49 and four replacement 125 volt 4 amp fuses. The whole repair cost about $5.00 and a few hours about learning about electronics. The TV works great! Good times!

I'm not too familar with this model, but to give you some pointers, you will find when you have this problem the fuse will go straight away as there will be some of the semi-conductors short circuited. Check your bridge rectifier diodes & also the chopper transistor in the power supply. As a general check, test most of the diodes & power transistors & replace any that read short circuit on your meter. Hope this may help you as a guide line.

SOURCE: LG 42PX4MVH PLASMA TV - Sound but no picture.

I have the same issue with my LG 42PC3DVA and I narrowed it down to the Y SUS board. After a little research there are a few items that are prone to go. The ceramic fuses (as you found), sometimes the capacitors on the Y SUS, Z SUS, and power supply go along with them You can tell because thy will be bulged at the top instead of flat. I replaced a few of my capacitors - they are only $0.89 each so it was MUCH cheaper than a board.

The other thing that is common on the Y SUS in particular are the FETs (also called MOSFET). They can be replaced if you are good with a soldering gun but they are static sensitive so be grounded. They are also a bit tricky to test so you may want to do some research on how to determine if this is the issue... or you can just replace the whole board.

Sylvania LC321SS9 B 32 LCD, won't turn on


Has this unit been near a lightning storm lately?/ Not that this is your issue. But I've had a T,V. do the same thing to me. I took it apart hoping it would be a blown fuse. But i was told a capacitor was blown out

Sylvania LC321SS9 B 32" LCD, won't turn on


Hi Stephen,
TV won't turn on means the power supply section is dead. Open the back cover if you can. Check up for the blown fuse. If the fuse is blown, replace a new one of the same rating. If the TV works, enjoy viewing and if the fuse blows again consult some TV tech. Never try another fuse with higher rating. It might seriously damage your TV. Good luck.

Sylvania LC320SLX 32 in. LCD TV wont turn on


There is short circuited component/s at its main power supply regulator board. Check and replace them. It is best to replace the circuit board as card bassis, rather than trying to repair it.

How do I test the y-sustain main board from a philips plasma tv...tv model is 42PF7220A/37 the Y-Main sustain number is LJ92-01200A....both buffers tested bad but now I dont know how to test the y-main...i...


Hi.

As such boards are cheap and fail quite easily (both the two sustain and the buffers) Philips service manuals are more oriented at board swapping then at proper testing. In this particular case the buffer boards fail very easily because of a bad soldering to IC. The short will regularly blow the main sustain board.

To start when a main sustain (e.g. Ysus) is fried the TV will go in protect mode with the led flashing in standby. One test is done disconnecting the Sus board (with power off) and restarting the TV. If TV does not go in protect, then the sustain board was good.

If there is no protection:

The first thing to check on a main sustain board is the fuse. If the fuse has blown the IC is probably fried.I believe fuse is F5004. Check for swollen capacitors that may have blown. Test the FET. That is the core of the board as it is the power amplifier.


Here the service manual:PHILIPS_SM_15540.pdf - Right Click "Save Target As"

Here a more useful service manual. Check and follow troubleshooting diagrams in manual.

Here some troubleshooting from users.

Note:if buffer board was shorted, then the main sustain board is usually faulty.

Regards.

MY VP42HDTV WILL NOT DO NOTHING WHEN I PLUG IT IN WHAT COULD IT BE.


Hi if you plug it in at the mains and switch it on and you get nothing not even the standby light then this points to either a fuse been blown so check the fuse in the plug failing that it will mean getting a new power board fitted, now if the telly is more than say 2 years old i would say its not worth getting fixed as the chances are you will replace the power board and then you will start having problems with the inverter, soyou could end up throwing money down the drain.

if its less than 2 years old and its totally dead check the fuse in the plug change it anyway and then give it a try but if its still totally dead then this points to either the fuse been blown in the telly this is a little clear glass fuse located where the mains cable plugs into the main power board, if this fuse is not blown also then the whole power board will need replacing.

let me know how you get on or if you need further assistance ok

plz rate this solution as i have a whole page of unrated posts, thanks

I have a sylvania LC200SL8 which went dead. Repair shop said it needed a new "Mother Board" (pn A7140UH) which I replaced. Still does not work at all. Any suggestions?


Power supply voltage outputs should be check first before anyhting else is replaced. I see that it has one main board which has the tuner, inverter, power supply all in one. What do get right now?

If you are certain that the capacitor is OK, there could be a different problem on the main power board or even on the sub-power board. The sub-power board should have output voltages even if the main power board is defective.
