Hi
the problem is a horizontal deflection source
it could be a shorted horizontal out put transistor
also causing the transistor to overheat and go short is the flyback transformer

Engine does not revs out and check engine light is on


Hello... Here is something that might work for you. First jumper the DLC red connector under the seat. Jumper the green and brown wires so that It can get the check engine light to blink and give you the codes. As you watch the light you will notice a pattern, something like... Three blinks for 3 followed by Two blinks for 2. Making the code 32. Right down all of your codes and then do a search for them over the internet. This should put you in the ballpark of what may be your problem.

Good Luck

My PT-50LC13's LAMP and TEMP light blinks 4 times and POWER light blinks 8 times continuously with 2 second intervals. I replace TY-LA1000 and FBL12G12L2CS Fan, but didn't fix the problem. Can anyone tell...


Listen carefully to the TV after the relays click. If there is a mechanical ticking or snapping noise after power On, replace the lamp because HV is present (causing the ticking). If there is no ticking sound, replace the ballast. You can confirm this by using the LED blinking pattern to localize the problem. refer to Service Manual or technical guide on the panasonic website for more help diagnosing LED patterns

Printer won't print, get flashing lights


Not enough detail to fully answer your question; need to know the pattern and colors of blinking lights.

Printer lights blink in certain patterns to tell you about specific problems.

Read this document until you see the pattern that your lights are making. The solution is below each pattern.

Movie stuck in ps3 wont eject try to turn on and red light just keeps blinking but nothing happens

You can try searching the gilksy method on a search engine or look it up on You tube. This is a DIY method. Some people have had success with it, but it’s far from a “professional” fix.

If you want it done professionally, I know that in the US Knight’s Gaming Repair is a reputable source, and in Canada Console Repair Guy is good.

Hope that helps!

'99 Ultra engine code 1 blink gap then 6 blinks,


Trouble code 16 indicates the ecm (engine control module) saw a battery voltage less than 6.2vdc or greater than 15.5vdc. The lower reading typically occurs during activation of the starter or indicates loose wire connections. The higher reading is usually caused by a faulty voltage regulator.
