Changing the convergence IC's could cost $300-$400 total.CRT based TV rear projectors are more or less obsolete now,with everything going to DLP and LCD.These days 5 years is the expected life on these TV's (most extended warranty contracts only cover up to 5 years)

funny that no one's been able to help you, because I accidentally discovered that the power supply cord for my computer worked for my Protron PLTV-32C lcd...  not sure if your model is different in someway, but you may want to try the cord from your own PC first, 
and if it works.

The technician may be right or he might not want the job, to confirm ask another computer repair shop for a cost to repair.
It is impossible for me to advise of the cost without seeing the extent of the damage.

If it's possible, install a small computer style fan and direct the air stream over the power supply. You should then get another 10 years out of it. Unit needs ventilation and cooling air. Hopefully, it isn't installed in tight quarters.

It wont turn on at all


Good day to mam wendy311!!!!


If you TV is totally dead set and no red light or green light on the front...


if that so the problem could be cause of dead set power power supply board...

You have 3 choices its either repair it on your own or took it to the technician or buy a new set of power supply board..

But for me I suggest to buy a new power supply board because if you took it to the technician cost of repair is almost or higher depends on the bad parts than the new power supply board...

But before you buy a new PSU please check this simple and common parts that usually cause of dead power supply board..
  1. Transistor----Check if shorted
  2. Capacitors----Check if bulged or leak.
  3. Resistors----Check if open or change value..
  4. Fuses---------Check if busted..

I hope this solution will be helpful..

Thanks for using fixya...

No power


HERE'S THE ANSWER TO YOUR PROBLEM:

The main reason why your TV won't turn on is because of its power supply board. This power supply board are composed of capacitors that are the responsible for the proper supply of current to your TV. If one or many of these capacitors are already burned out or "dead" your TV won't turn on at all. Here's what you've got to do:

1. Open your TV or let somebody do it, much better a technician.
2. Check the Power Supply Board.
3. Check the capacitors. Remove the "dead" ones and replaced it with "new" ones. You can buy capacitors to the nearest hardware in your town, or to your service provider.

I would suggest you to do it with a presence of a TV technician, so that you will be guided properly. Thanks for your question. I hope it helps....

I have an acer AT3220 lcd tv i had problems turning it on now it just shows a red light wont turn on at all any ideas ie which capacitor or any other information would be brill as im now back to a 28inch...


Open the back of the tv check th epower supply for busted/leaking or swollen capacitors - if you have experience solder some new ones in place - use the 105degress one for a longer lasting capacitor - the radio shack ones will work but they are rated at 85 degrees and wont last as long.

I have Toshiba 15" lcd tv with vestel 17ips01-2 psu/inverter board.the tv will show a picture for a couple of seconds and then the inverter cuts out.


There are a few things that can cause this fault, but the most common is the High Voltage Capacitors that feed the backlights going bad. The invertor and power supply are on the same board (Vestel 17IPS01-2)

The caps are on the power supply board and are C355 & C356 (12pf 3kv) and C354 (4.7pf 3kv). If you replace these caps it will solve the problem in 99% of cases.

If replacing these three caps do not solve the problem then it may be easier to replace the power supply board... as fixing means replacing a tiny surface mount chip with loads of legs.

WARNING: The Power Supply/Invertor board can contain LETHAL VOLTAGES even when turned off and unplugged. if you are not sure, Pay someone to do it for you!

TV repair


The local technicians in Macao say, there is no way to repair it, it is totaly wrong it can bw repaired easily. need to buy a new one... not at all. Is there a problem in a major component or design that make it no viable to repair? in tv no major components except CRT. Any problem with power supply I can do by myself, if you have basic knowledge of electronics you can do it but as you know it is a high voltage device. so bettre to get help from tec. as per fixing is concerned as you are saying power supply it could be due to 1 main filter cap. 2 bridge rectifier diode. 3 switching ckt components like transistor or str. 4 print short. hope this will help. good luck.
