Sylvania LD320SS8 needs inverter transformer

I have a Sylvania LD320SS8 where the screen lights up briefly before turning off. I'm pretty sure I need to replace a transformer in the inverter circuit. My question is that I have a broken philips 32 lcd that appears to have nearly identical transformers in it. Sylvania - JS HVT-127 and the philips is JS HVT-153.

    I ordered a replacement transformer and the problem is fixed. Shorted tansformers are common problem for this lcd.

Take the Inverter Board out and check for Open windings on the 6 Transformers along the edge of the board. When you find one open, get the number off of the Transformer, Google it, buy one and replace the bad transformer. I was given one of these TV's and fixed it for $11. It's not rocket science, if you can use a DMM and a soldering Iron, you can fix this.

SOURCE: vertical lines in my sylvania lcd tv

They go away after 10 minutes of what? **** She Wrote? Dancing with the Stars? Or simply being powered On? You have some cold solder joints on one of the PCB boards. Once they heat up they work perfectly. The only way to fix this is to have them reflowed by a tech with a soldering tool or have the board replaced. Good luck! Cheers

This morning the power went off briefly. When the power came back on, the monitor screen would not light up. All connections are good, and the power light at the bottom left of the monitor turns green...


Go check the backlight inverter lamp, replace if busted.
This can be found when you open the back of your lcd and manage to get access to it.
The backlight inverter lamp is located at the upper and lower part of the screen.
Go check also the inverter board, the one that suppply high voltage to inverter lamp, see if this ballast transformer are not burnt out.
The input voltage of the inverter board is 24vdc the output is 250v ac..The voltage input terminal of the inverter board usually creates a loose solder. Use a soldering iron to resolder them....

Hello,

You may be able to repair the board instead of buying a replacement board. If you are up to a little soldering it may save you a good bit of money for the repair. If you are interested just take a few pictures of the boards and email them to us at tech@ccl-la.com We will check them out and give you some pointers on what to do. Most power supply issues with the blinking power lights are caused by blow capacitors on the power board. These are fairly easy to replace and the replacements are less than $20 usually. To get an idea what capacitors are and what will need to be do to repair you unit check out our pages at :http://www.ccl-la.com/blog/index.php/capacitors/ You may want to look over the repair guides for other units we have posted too. If you need parts we can also supply them for you. If you have any additional questions just contact us at: tech@ccl-la.com

I hope this helps, If so please rate our solution.

Television when turned on: light goes to green then flashes twice. green light goes out and red light comes on. tv will not come on.


If the Red Light Blinks twice and goes out, the TV is in Protection Mode. There are 6 voltage outputs to the lamps around the screen. If one of those outputs is missing the TV will sense that there's a problem and refuse to turn on. The predominant failure in this model are the output transformers on the Inverter board. A properly trained technician can measure the windings on each transformer and look for an open circuit, if one is found, replace that Transformer. i was given one of these sets from a friend and I replaced an output transformer ($11 w/shipping) and I now have a fully functional TV/DVD Combo. Also verify that all of the connecting cables internally are properly seated, there have been reports or the ribbon cables from the Power supply board to the main board above it not being fully inserted and it also prevented the TV from turning on. A word of caution. There are VERY High Voltages on the inverter circuit board, only persons with proper training and knowledge should attempt this repair.

Blank screen after brief picture (failed inverter) relisys 1730


With the PWB removed from the TV, Measure across the outputs from the Transformer. The impedance(resistance) will be the same for all the outputs. You can find all open and some shorted outputs this way.

The DC input voltage is generally split amongst the Output transformers. you can pretty much measure from ground to points on the circuit checking for opens and shorts

Those things that look like a signle FETs are acually 2 FETS with the outputs tied together. This is tricky because if you are looking for a Single FET opposed to 2 you don't diagnose them properly. (this is only for the generic inverters provided with Samsung, CMO, LG,etc. Companies like Sylvania and Funai make their own so although the circuits the same it will be more obvious whats going on).

Just know that the inverter is usually composed of 2 to 4 identical circuits. Seperate the circuits then compare 1 to the other looking for differences. That difference is usually the defect.

Is it under warranty by chance?
What is happening is when you turn on the TV, it's trying to power up the screen at that moment. If it can't power up the screen, it will turn off automatically. This is what they call, "Protection Mode".
All the TVs made by Funai (Emerson and Sylvania) are having the same problem. The Inverter Transformers needed to power up the screen are somewhat low quality and burn out easily. I'm sure of of them burned out.
Your TV, I believe, takes 6 of those things to power the screen. And they are all on one circuit board.

If the TV is not under warranty, then let me know what the board number is on that circuit board. The board inside the TV should have maybe 6 connectors that hook up the screen. I may be able to track down a replacement board for you.

Programing one for all remote for a sysvnia model tv ld320ss8


I also own a Sylvania LD320SS8 HDTV. My solution to the
problem of remote codes that won't work is to junk the
Sylvania, and buy a reputable brand TV such as an LG
HDTV which will work nicely with DirecTV or Dish network
remotes.
