'94 Gmc Sonoma 4.3L Starts loosing Power and making weird Rattle Noise when reaching operating temperature. Also water tank looks like there is a bit oil in it. Could it be the cylinder head gasket?

Oil in the coolant is usually an intake manifold gasket problem on these engines. If a head gasket failure the engine will normally overheat and give erratic temp guage readings. Make sure the oil level is full. Is the rattle noise coming from the engine? Some times the exhaust (converter) will fail and the catylist will seperate causing a rattle noise from the exhaust and plug it up giving a no power situation

I have sound, but no picture. A bright horizontal line appears across the TV screen, again, no picture ?


Thanks for using FixYa. Heat is the number one enemy of electronics, and these sets operate hot. This problem is caused by the power supply being overloaded. This is often caused by failed convergence ICs. The safety circuitry shuts the TV set down when it detects a problem. Some parts for this TV will be hard to impossible to find. This model of TV has over 3,000 parts which include millions of transistors inside the integrated circuits. Over time the capacitors will change value, leak and become defective. Resistors will change value and burn. This will cause other components to become defective. This can has 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 since if the parts that caused the failure to begin with are not replaced. The typical cost to get this fixed by a pro is about $300 - and it doesn't mean that he/they will do a job better than you do. The parts are less than $100 (about $20-$30 for the IC's) if you want to do it yourself. Replacing only the IC's MAY solve the problem; however, many people have also had blown resistors requiring replacement. Why would you ask should you replace both of the IC's if only one is shot?! If one is shot the other one is not far away and for that little price of the chips it worth changing them both at the same time. Also the convergence board should be checked for cracked solder. If you replace the ICs and the resistors are shot, the ICs may blow again almost immediately, meaning you may have to do the repair twice.

Please do accept the solution if the issue is resolved or else revert for further assistance.

My Panasonic LCD had a little pop sound and we completely lost our picture. I just bought a new lamp TY-LA1000 and I turn on the TV and the switch color goes from flashing Green to flashing yellow 2 blinks...

You probably need a new ballast.It is a high failure part.If you listen at the back of the set you can hear the ballast make a short buzzing noise every time it tries to light the lamp.If you don't hear this then your ballast is probably bad.

Samsung HL-P5063W makes a whining sound and then goes off

The most common failure in the DLP that makes a whining sound would be the color wheel. They cost about $135 + labor because I wouldn't advise changing it by yourself.

Motor runs continuously

the magnification motor cannot find its home position at this time, causing a erratic operation, soon enough the motor will wear up and would cause you more damaged. you need to take this to repair center and either clean the sensor or replace the home positioning sensor
