Regarding part # 239111

Does this part have to be desoldered and soldered into the main board. 1st time doing this stuff. also, since you have experience, if i buy a new main board, does it usually come with the flyback and everything on it? or do i have to buy piece by piece ? Thanks in advance for your reply.

Good Day;

This a solder in part, you may want to consult a factory authorized service center, it's not for a novice. Good Luck, big IRISH.

During a storm a bit ago all the HDMI ports stopped working I am looking to fix them finally and wondering if anyone can help w a part # and instructions.


A basic understanding of electronics helps. I would look inside on the board and follow the traces from the hdmi back to the chip that feeds it. It would likely be an ic that has a voltage regulator in it as well as something to convert the serial port data. Write down the numbers on the chip and go to or phone an electronics parts supplier in your area and they will consult a cross reference manual to see if an after market version of the chip exists. If not they will order the original. Once you have the chip, you will need a decent soldering station ($100 or so) and a solder sucker. The solder sucker is used to desolder the chip or component slowly. Don\'t overheat the component but desolder as far as you can. then wiggle each leg one at a time until it breaks the remaining solder. If it does not wiggle off heat it again then wiggle it. Once all unsoldered gently pry out. (any other attempt to desolder without a solder sucker will damage the printed circuit traces) Before removing the ic verify which pin is pin 1. It may be printed on the board or a corner of the chip is marked somehow. Place the new chip in with pin 1 in the proper location. Use hitech solder that is hollow and contains flux on the inside to resolder. If the wrong solder is used the flux may attack the components and it will fail within a year (plus or minus). I would suggest finding someone who already does some electronics to assist you or to do the whole job.

My Poineer SD-P5795W television is 11 years old and has been in STANDBY (red light) mode most of that time. Recently when I turn it on it will only stay in ON (green light) mode for near 2 seconds and then...


Hello there,
When your television refuses to turn on and all you have is the standby light or the green light turning on and then going off in few seconds, that is a sign that there is a problem inside of the unit.
When the television gives off signs as this,it could be as a result of one or more factors going bad inside the unit of the television.
The factors that could cause the problem is eithere there is a bad capacitor on the main board or the power control board(PCB). Or the lamp is bad. It could be one of the two facotrs or both, therefore, this will result in you running a check on these factors.
To test and replace the bad capacitor, you will be in need of a screw driver, soldering iron, desoldering braid, soldering wire and replacement capacitors. Unplug the television, turn to the back, unscrew the screws that hold the back cover off the television, then you lift up the power control board and assess it for any capacitors that looks shrinked, swollen or burnt out. Once it is detected, trace it to the back of the board, then you desolder it off the board, get exctly that type of capacitor and fix into the board and solder it back on using the soldering iron and soldering wire. Please be very careful about it, in order for you not to create a bridge.
Do the same for the main board of the television, the main board is usually clipped onto the frame of the television.
For the lamp, you will have to reach out for your user manual, as am not keen with the location of where the lamp of your model is located, but once you locate it, have it checked and replaced with a new one.
That should solve the problem for you. If you are not familiar with such technical/electrical fix, i will suggest you get someone who is familiar with such to handle the fix, because televisions are well known to store current over time.
All the best Elect_Comp

Works fine untill the kids stomp on the floor then it flickers and picture turns oval or even goes blank


Sir the problem of your tv is just a cold solder or loosed connection, try to tap the side of your unit it will react. If you are handy in electronics you can repair it by your self using a soldering iron, soldering lead and desoldering pump. If you remove the back cover of your unit be to unplug your tv to main ac outlet. then pull out the main board be careful when removing the main board some connectors may accidentally remove try to put some marking to the connectors. It is much better if you have a magnifying glass to easily identify the loosed or cold solder. When resoldering be sure not to connect separated pin if accidentally solder or joined together it may cause much problem to the unit. Or you can contact a service technician to do it for you and save you from stress good day and best regards.

How can chang sony tv stk ic


if it is a sony check to see if any of those little green resistors are blown first. most sonys have the stk chips on the main deflection board.they will be next to each other with a big heat sink on each.have a soldering and desoldering iron ready as well as tape and marker for the wires.. remove the wires from the board you dont have to take the board all the way out. start desoldering each pin. if some pins are stuck just touch the pin with the iron. clean the heat sinks.apply themal paste to the new ics. put the new ics through the holes and start soldering. this part can be tricky. put the tip on the pin the solder will flow just quickly remove the solder then the iron 36 times and your done.

When i turn the television on the green light goes off after a few seconds


Your television is protecting itself from further damage and that is why the television is shutting itself down. When you remove the back panel of the television with the power supply unplugged from the wall, you will see a black box which looks like a distributor on the board. You will need to remove that board and look underneath at the soldered connection points of the transformer. RCA went to a lead free solder and the solder is known to crack. desolder and re solder the transformer using either desoldering braid or a desoldering iron and resoldering using silver solder and a pencil soldering iron no bigger than 35watts. After you do that check the 3 fuses next to the transformer using a multimeter. You have a blown fuse. Order the fuse from Partstore.com and replace it.

It's definitely the one causing the problem but I suggest you also replace or resolder the 4 capacitors on the DM board to make the job at once. Just make a note on the polarity markings of the capacitors and the board. If there's no indicated polarity markings on the board then nevermind. Here's what you need to do the job:
  1. Soldering iron
  2. Desoldering pump
  3. Soldering lead
Steps:
  1. Heat up the soldering iron
  2. Melt the lead on the board with the soldering iron and use the desoldering pump to remove it and loosen the terminals of the capacitor.
  3. Remove and replace the capacitors one at a time to avoid confusion.
  4. Make sure to make a good solder. A good solder is volcano-shaped.
  5. Cut any excess lead terminals.
  6. Make sure there's no stray leads that might cause short circuit on the board.
  7. Check the terminals of the newly installed capacitors for any short circuit.
Tip:
The board experiences vibrations during the operation of the unit. These vibrations can result to broken solders as the time passes by. Before re-installing the board, check it for any loose or broken solders and resolder as a preventive measure. A magnifier will surely help.

Convergence ic


You will need to replace your convergence IC's. They are located on the D Board, left side board that is mounted flat on the bottom. They are on the two large heat sinks you can see at the back of the tv. Get the part numbers off those and order some new ones along with thermal grease. You'll need a good desoldering gun or braid and a good solding pencil. Buy thin soldering not the thick stuff. Radio Shack is a good place to get irons and solder for the job.

On The H/V Generator


you will need a desoldering IRon or solder wick to remove the old solder so the HV generator can be removed. Both of these are available from radio shack. also the solder that works best for printed circuits is radio shack part # 64-006 solder.
