Skipping upon accelaration 1399,1456 and 401 codes showed up


oh yes i know its you EGR valve (Exhaust Gas Recalculation)

A code P0401 most likely means one or more of the following has happened: The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced There is a blockage in the EGR (tube), most likely carbon buildup The EGR valve is faulty The EGR valve may not be opening due to a lack of vaccuum Possible Solutions In fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit. Use a vacuum pump and pull the EGR valve open while monitoring engine RPM's & DPFE voltage. There should be a noticable difference in RPM's with the EGR open Clean out the EGR valve and/or tubing to remove deposits Check the voltage at the DPFE, compare to specified values (refer to a repair manual for your specific model) Replace the DPFE sensor (with a good quality / OEM one) Replace the EGR valve Related EGR Articles: P0400 - P0402 - P0403 - EGR System Explained

Hitachi rear projection model 57f59a makes loud popping sound from time to time


Yes and it is common---the set uses 3 picture tubes and where the high voltage (well over 10,000 volts) goes into the side of each tube via a spark plug type wire (with good reason) they completely seal the rubber clip that inserts the wire into the side of the tube.

You are describing almost perfectly when one of the tubes arcs around the anode (what the opening is called--2nd Anode to be precise)

Two things are going to happen--when it pops it can instantly burn the coating off of the offending tube's screen resulting in a burn mark--usually dead center and if red tube arcs the mark will be yellow(only red and visable in that area of the screen.

This damage is permanent once it happens-----Second is that it will arc hard enough to blow some other part out in the set.

let me know if questions.

My tv is showing alot of red with blue blotches across the screan


Your TV most likely has fone of two possible problems.

Problem #1 - Failure in the convergence circuits. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem


  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
Here are some photos of convergence problems.

645fba6.jpg
0dcec37.jpg
Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

0667c5f.pngSOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed. Notice how dull the colors are and how white the screen looks. The screen may also look red, orange, dull, etc.

TV set after fluid change. Notice how bright the colors are now. Everthing looks crisp and sharp again.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Have a kent r/o system dont know how to hook it up is there any way someone can help


Make sure that all valves are in the open position.
Try to recharge the water storage tank. Here are the steps to follow.
* In General: When any type shut-off valve handle is positioned so that it is parallel or in line with the tubing that enters the valve, valve is OPEN. When handle is turned perpendicular to tubing that enters valve, valve is CLOSED.

Necessary Supplies:
1) Tire Gauge marked in 5psi increments (ie 5, 10, 15, 20psi, etc.)
2) Bicycle tire pump for standard type bike tire valve
To recharge RO system tank:

1) Close cold water feed valve (valve located at some point along the cold water line from street plumbing).*
2) Leaving RO tank valve on, turn tank on side & locate valve stem on bottom side.
3) Remove stem cap.
4) Drain all water out of tank through open RO faucet into sink. (Continue to leave RO faucet open throughout procedure)
5) If current tank pressure is insufficient to empty tank, apply tire pump to valve stem and pump 10 – 15 times. Exit flow will increase and then gradually decrease as pressure equalizes. Do not overcharge internal bladder of tank during this
procedure.
6) Repeat step #4 until tank is completely empty. (Tank is empty when additional pumping produces no more water)
7) At this point, adjust EMPTY tank to exactly 7psi. (Gauge reading midway between 5 & 10psi is sufficient)
8) Turn off RO faucet.
9) Replace cap on valve stem and reposition tank in upright position.
10) Open cold water feed valve.*
11) System water is useable immediately, however, tank will take 3-4 hrs to completely refill.

Low flow hot water in Delta Shower


If your water heater is old or has been recently replaced, it will slough off debris that will get caught in the hot water supply side of the faucet. You have to disassimble the faucet and use a dental pic to remove the debris from it. This is a real common occurance. You can also try to flush out that side by removing the parts and then slowly turning on the water without the parts inside. Be careful not to flood your bathroom when you do this. But usually you have to dig it out. I have spent as high as 3 hours digging the liner from the dip tube of a water heater out of a faucet.
