Awesome, glad to help. IT is a common thing to happen. They just don't build em like they used to. The boards are getting thinner, the mountings are getting less, and the casings are getting more flexible. Good on YOU for fixing it. :)

remove the rear cover to access the main board, then you can do first with re soldering cold soldered component parts at video section which get loose contact to the pcb ( printed circuit board ).just let me know if it works good luck.

My sony triniton manufactred in 2000 satys in a screen with horizontal lines it does change color but cannot see image i used to shake it a little and would be able to see it but now i cant can u haelp me?


This sounds like a dry joint on the vertical deflector chip. If you are able to use a soldering iron you may be able to check the main PCB and resolder and joints that look like they are cracked. You can also check for any capacitors which look like they have bulging tops (instead of flat tops).
Opening a CRT TV or monitor should not be attempted by novices. There and components whcih store high voltages even after theTV is switched off and unplugged. The CRT can also become highly charged and is dangerous.

My tv when i try to turn it on doesnt come on it only turns the little red indicator on and off continually can this be fixed?


Possible that the TV is having some dry soldering in the power supply sections or in the processor sections in the main board.
It will be good to remove the power plug and check all the leads, the connectors and the PCB for signs of dry soldering.
If so use a good iron and do the soldering of the suspected joints , check also the processor pins.
If not you will need to check for shorted components in the main board , check continuity , check the voltage from the power supply to the main board.

I have a sony 32'' I think. model # KV-32FS10, serial #8047927, made Jan 2000. During a move, the tv was dropped and now when you press the power, your hear the click, the red click light flashes...


It sounds like that in the drop you may have cracked the main PCB. The PCB's usually crack around the heaviest part of the PCB. Probably around the flyback transformer.

Philips TV Model 32DW6557/05 Screen Problem


hi it sounds like a capacitor in the verticle circuit located on the main board. it is near the verticle ic. the verticle ic also could be bad the cost is around 85 dollars for a tv shop to fix. sometime a cold joint could be found around vert ic. a soldering iron is required with solder.tap the side of tv if picture comes back it is just cold solder joint.

No Red- Intermittent


Hi,

A short answer, YES. I suspect a cold solder on the red drive transistor. That transistor is one of 3 identical components (one for each of the blue & green). They are normally found in a small squarish PCB that is connected to the rearend of the picture tube. In some instances, they are also heatsinked. More often you need to remove the shield/screen protecting the foil side of the PCB. This has to be done gently since it can easily crack the glass holding the pins.

Cold Solders are corrected by applying heat from a soldering iron and probably a dab of solder lead. Solder joints should be shiny (not dull gray) with no air bubbles.

If your concern has not been corrected after completion of the above procedures, you may need to replace the red drive transistor. it might also be worth your while to check for any other component that may suffer from cold solder and/or any loose connection(s).

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FIXYA.

Mitsubishi WT-A42


I repaired a convergence problem on this model by locating IC8C01 and IC8C02, the two large convergence chips on the main pcb(center board) and solder all the leads making sure not to leave any solder bridges! The unit was over 4 years old and used often. Those chips get pretty heated and make the solder brittle and crack around the leads.

Toshiba 32A10 Sound but no Picture, Red Light Blinking


Your set has cracked solder joints, most likely on one of the small regulator transistors on the main board, with its own little heat sink. I have seen that many, many times, and it is a very simple thing to correct. Loose solder joints on the vertical output IC can cause no picture too, but it is usually those regulators that cause the problem. The set needs to have those regulators, the vertical output IC and all other major components resoldered and the set will play fine. If you do not have experience resoldering small parts on PC boards, allow a qualified tech to handle it for you.

No blue color on screen


Check for an open R15103 on the CRT drive board. It may have been one of those discolored ones you noticed. I think it is a 10,000 ohm 2 watt resistor. You may want to replace R15101 and R15102 at the same time to prevent those from going out as well if the 15103 resistor measures open after you remove it from the neck board.
