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

How to determine if a plug on the back of a TV is good


Have you checked for a cracked circuit board. Very minor cracks in a circuit board may cause a break in the circuit when the boards are flexed slightly. Loose solder joints will also cause problems when boards are flexed or stressed when screwed tightly etc.

How to repair broken handle? Handle was firm, now extremely loose and detaching from main unit.


Hello,


Please allow us to try and help you.

The Handle is part of the TV's CASE in other words if the handle unit is broken then the case would be damaged as well.

Here is what you can consider on doing.

1. Find a TV that was listed for parts only www.ebay.com would be the best source,
2. Take the guts out of the old TV and place it into the CASE you do buy.

Here is the issue that is in front of you though to be honest. Ebay search when i did it was not so positive the reason is because not to many of these are being sold.

You might want to consider Liquid metal witch is a glue/paste then take the TV apart and apply some of that to the piece that is broken or that might have came loose.

There is just no real escape form these issues unless the unit was under warranty. The handle that is loose came loose over time and it might not be far form just falling off.

I hope this does help please do update me with any further information you might have on the loose handle.

Thanks for using fixya.com

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.

My gpx under the cabinet tv comes on, but after a few minutes the sound gets static in it, then I lose the picture, but the sound comes back perfect.


Double check the cabling, loose cable will case such issues, also try a different cable, if neither works, most likely you will need to exchange it.

Can't get satallite channels


If you are on Satellite then it only works off of channel 3 and you will not get any other channel on the tv set. But you will need to turn your sat box remote to change channels.

Tv looses color


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.

Schematic/manual needed for RCA 27V412T Color Television repair


Look for the vertical IC. It should be a small flat IC attached to a heatsink and marked something like LA7837. The IC will have a circuit designation like ICxxx. For example IC301. Check all of the caps in the same circuit (C3xx). One or more are bad &/or intermittant. Start there and keep us posted.
