Check all the connection, re-check the dmd board and if all that proves nothing could be a bad wheel right out of the box.. Might also look closely at the light tunnel and see if the four small mirrors in there look clear.

My 32inch tv turns on but the picture is wired.


On a 32 inch it may not be worth fixing--not going to be a reset etc--base decision on fact that possible repair should not exceed used value of set--which in my view it likely will.

Ijust get a light screen!! no sound, no menu, no nothing


Internal capacitors have probably gone bad (bulged and leaked) and therefore there is nothing that can be done short of soldering new caps into place, and hoping the old one's didn't damage anything else on the circuit board. Recommendation: replace it.

Have a 29 inch 5 or 6 yr old rca color tv lately we get a colored horizontal bar across the top of the screen and the other day we have fuzzy black lines across the entire screen


Hello,


CAUTION: To prevent damage to the CRT phosphors, immediately turn down the brightness so the line is just barely visible. If the user controls do not have enough range, you will have to locate and adjust the master brightness or screen/G2 pots.

A single horizontal line means that you have lost vertical deflection. High voltage is most likely fine since there is something on the screen.

This could be due to:

Dirty service switch contacts. There is often a small switch located inside on the main board or perhaps accessible from the back. This is used during setup to set the color background levels. (On some sets, this is located on the CRT neck board and may be a jumper plug or other means of selecting service mode - not an actual switch.)

When moved to the 'service' position, it kills vertical deflection and video to the CRT. If the switch somehow changed position or got dirty or corroded contacts, you will have this symptom. Flip the switch back and forth a couple of times. If there is some change, then replace, clean, resolder, or even bypass it as appropriate.

Bad connection to deflection yoke or other parts in vertical output circuit. Bad connections are common in TVs and monitors. Check around the pins of large components like transformers, power transistors and resistors, or connectors for hairline cracks in the solder. Reseat internal connectors. Check particularly around the connector to the deflection yoke on the CRT.

Bad vertical deflection IC or transistor. You will probably need the service manual for this and the following. However, if the vertical deflection is done with an IC, the ECG Semiconductor Master Substitution guide may have its pinout which may be enough to test it with a scope.

Other bad parts in vertical deflection circuit though there are not that many parts that would kill the deflection entirely.

Loss of power to vertical deflection circuits. Check for blown fusable resistors/fuses and bad connections.

Loss of vertical oscillator or vertical drive signals.

The most likely possibilities are in the deflection output stage or bad connections to the yoke.

Screen is incredibly dark, as if it was burned; cannot adjust color, tint, brightness, etc. When we bought the tv, it had a beautiful color, but now...


The LCD back light has blown, to buy a replacement you will have to visit the naxa site and see if they do spare parts, or can give you a contact number for repairs. Because it is a small lcd changing the back light might be tricky, it might be worth taking it to a repair store to see how much it would cost for the repair.
I hope this helps a bit, sorry i cant give any more info on how to get a replacment part.

Magnavox 42mf438b/27 color distortion. Colors are extremely bright, bleeding together with little black. Sometimes it will clear itself up.


do to menu; then change the brightness/contrast/sharpness/color controls down also make sure the tint is in the middle.

Noise in color wheel and has actually quit working now


It likely isn't worth fixing because the repair will probably cost a minimum or $200 to $250 and a new 42" LCD at walmart.com is only $578. Do you want to put half of the cost of a new LCD into one that will still be out of warranty after you repair it?

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please post a comment if you need additional assistance so that I can help you further.

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.
