Tv looses color

I have a sylvania TV, model SRT2232X that will periodically loose color. The TV will work perfectly for long periods than change to shades of green, grey and black. After a period of time will go back to full color? Any idea what could be causing the problem and is it a relatively inexpensive fix?

Please advise.

Thank you in advance,
Karen

Hi and welcome to FixYa,

Initially, your concern could be any of three (3) possibilities:

  • logic controller IC (most likely);
  • 3.58 MHz crystal (likely);
  • chroma IC (least likely).
Although the IC is mentioned, it is highly probable that it is not the IC itself that is defective but a supply voltage or a signal is missing. This then could be either a simple cold solder or a resistor that has gone up in value. The crystal sometimes internally looses electrical contact. You can try tapping on it to determine if it were so.

Since this involve opening the TV unit and working on the electronics, this would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Repair cost would be dependent on how you approach the repair. Parts I expect, would not be that expensive. However, if you avail of the services of a competent repair person, then it would be the service charge that would make the repairs cost more.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

Sure. You have a bad chip or two. Is it inexpensive. No. It will probably run at least $200 minimum go have it repaired.

This is what you asked for. Sorry to deliver bad news. If you want to know what chip and why we do have IC Techs who can answer that problem. But, this is no do it yourself poject unless you are very qualified.

You might be having problems with the Video IC, actually the section of the IC that controls color. I would first check to see if the color controls are working, I would also suggest checking the color presets and defaults. After trying these controls if the color can not be corrected then troubleshooting of the circuitry is needed for this I would suggest that you have a qualified TV technician look at the set and give you an estimate for repair.


I hope this helps,

My TV after being ON for about 10 minutes will shut off by it self. You can turn it back ON but it turns off rught away?


Hello
From your brief explanation I thinks that there is some loose solderings inside your TV. To make sure about it, you just give a small hit with your palm on the top or side or your TV, when it shuts down. Never use any hard material. Use ony your palm. If it comes on atleast for a short period of time, you can determine that there is some loose soldering inside it. As it is a 13" TV, and a small one, you can do it by yourself. Open the back cover, and pull out the printed circuit board inside, anc check for any component for loose contact. If it seems to be, resolder the point by applying a little more solder. Usually, some components of all TVs will heat up while working. Repeated heating and cooling can cause loose soldering contacts.
Do this first, and wants any more explanations, ask me through Fixya. Ok.

I'll bet you have vertical output IC with some pins not soldered. This IC ( integrated circuit) is a "chip" that makes the picture fill out from top to bottom. After a period of time heat will cause the pins to crack loose on the circuit board. You need to have a tech check it for you. Stargazer
