Broke I had a fuse go out when the tv was on. When I turned the tv back on, the picture was very faded and 5 seconds later the tv turned itself off. I have tried many times with the same results. I even unplugged it for 2 days with the same results. Any suggestions? Ken

Re: Broke

You are having a high voltage power supply issue I would not advise you to work on this problem yourself due to the dangerous voltages that are present. I would advise you to call a repair shop and get a qualified repairperson to take care of this problem.

TV randomly turns off. Screen sez COMP 1 with a blue screen then fades to a block screen. !5 -20 minutes later the picture restores back to the progressed program. WHY and How Do I fix.

Need to know what tv you have. If tech cannot fix it it may be best to just buy a new tv and could be a lot less exepesnive in the long run

TV turns on, then turns itself off about 2 seconds later.

set has a self diagnostic---after set does shut down press and hold MENU AND DEVICE(INPUT) buttons on front of set for 5 seconds----if 2 blinks, a pause and 2 more blinks: this is short protection error code---The set does use 2 Stk394-250 and each is protected by a pico fuse in the power supply---if either fuse is blown the set will shut down(it detects no voltage or missing voltage;) It is not uncommon for a shorted IC to cause this problem; if you locate the STK's look carefully at the resistors around them---if any are discolored or burnt---you have found your problem.

When I power up, 5 seconds later this back projector TV turns itself off

t does sound like a bulb problem, either its over heating and shutting off to protect itself, or its already shot. Give a TV repair shop a call and see if they can give you an approximate price, then decide to ditch or repair it.

Normal pictures fades to blue screen within 30 seconds

The fix for this is here somewhere, as I had the same problem last January and the solution was posted here in March last year. I'll try to find it and post the link to it for you, later.

Turns on and turns off.

Good Day;

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 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. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR LEAKY C9A60 470 PF 1000 V PART # 154P400030, PARALLEL TO D9A57 ON THE POWER PCB. 2. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. 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. OR your TV has "COOLANT" (ethylene glycol) on the circuit boards. This fluid comes from the CRT's (picture tube) this fluid is used to keep the CRT's cool, such the name. This fluid from the CRT's leak when TV is on for long periods of time, the chamber expands and the seals leak.

One can remove this fluid by using "acetone" & small brush. The fluid is hard to see, use bright light, they spots can be smaller then a DIME. Also, the fluid can corrode the parts and traces on the boards. To protect the TV in future place heavy plastic or thick cardboard over affective area, make sure TV has proper air flow around TV. Good Luck, big IRISH.

Sounds like your bulb is nearing the end of its life span you will be needing a new bulb soon.
