sound like it bad solder check your stk.
that run your conv .hope this help.

Need to have the power supply rebuilt, expect to pay around $350 Julio at [email protected]

it sounds like you may have a faulty frame chip. but could be capacitor. who knows for shure, exept an engineer?!?!?

Hi there,

By unplugging the TV for an hour or more you did a power reset. If this power reset does not allow the TV to turn on component failure is indicated. These sets are assembled using the wave soldering process they are known for having cold solder connections. Power supply failure is common. The safety circuitry shuts the TV set down or will keep it from turning on when it detects a problem. This model of TV has over 2,000 parts, which includes millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Diodes and IC can go bad. This may have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again if the parts that caused the failure to begin with are not replaced. The only way to know for sure which parts that are no longer within factory specs and for a proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment specifically designed for TV service and the skills to use the test equipment. I wish I could tell you there was a quick fix or button to push that would fix the TV but that is not the case or the solution needed to get the TV operating correctly.

Good Luck!!

Thanks

Simply put, there's another part that needs to be replaced, or the one that was replaced is defective. Call the repair shop that did the work for you. Their work is warrantied for 90 days. However, if your set needs a different part, and this is an out of warranty repair, you will have to pay additional costs.

on the frount you should have ch up , ch down,
same for volume , and menu. press menu
and scroll down to VIDEO or SET UP
try one of thoes sub menu will have FORMAT
4:3 - 16:9 seting its a little differant on
on same make diferant models , you may
have to do a little hunting to find the setting

do you hear static elctricity ( Crackel Crackel)
sound when you turn it on /or off ?
means you have H.V. if not the tripler is out
or the primary Fly back is dead .

what is the problem with the tv

In your On Screen Display menu (OSD), you should have a place that says "convergence". As a sub heading to this it will say "Auto-Convergence". This is where you want to be! Hit OK under AUTO, and watch the magic happen! If your set happens NOT to have AUTO, you'll have to do it manually. You're going to make the lines all match up doing one color at a time until all three colors are done! It's not hard at all. It may take a little patience at first, but just think of all the money your saving by not having a TV tech come out to your house and you'll be fine!

If you hook up a video game to a projection set or plasma there is always a chance of what is called “Burn-In”. This will only result from any image that is not moving on the screen for a long period of time.

I have seen this burn in on some people watching the HSN or QVC too much.

So in answer to your question, no it will not damage the Television as long as the game is not paused for hours at a time with no movement.


I hope this information allows you to resolve this issue.

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

either you crossed some wires or you jared the lamp adjustment so it is not projecting right!

your convergence circuit has started giving trouble .... normal thing after a few years running for projection televisions ...... could be that the convergence IC's are getting too hot (two big IC's on a heast sink bearing an STK number on it) or that you have some loose soldering that needs to be resoldered on them.... worth the check

The TV is on protect mode. The clicking sound is the protection switchthat keep turning the TV off to prevent further damage, this happenswhen a fault had been detected.

Good Day;

Shutdown at Power Causes: Cause #1 This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. SELF- DIAGNOSIS INDICATE X-RAY. CHECK FOR A SHORTED IC5A03 PART # 270P704010 AND AN OPEN R5A73 82K ¼ WATT OFF PIN 2 OF IC5A02 ON THE MAIN PCB. 2. SELF DIAGNOSIS ERROR INDICATES SHORT PROTECT. CHECK FOR OPEN FUSES F9A04 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT. 3. SELF-DIAGNOSIS INDICATES SHORT PROTECT. CHECK FOR A SHORTED IC4B01 PART # 270P261020 (VERTICAL OUTPUT) LOADING 24-VOLT SUPPLY LINE. LOCATED ON THE MAIN PCB. Good Luck, big IRISH.

the obvious check would be the mains plug .if this is ok could be down to a dry joint or capacitor fault. amonst other faults. try taping round the back cover if the problem stops you have a bad conection or dry joint.good luck farr64

well you will have to goto or thru menu try to reset to factory setting seems to me it is possible
what is wrong with the settings now?good luck
