Gateway laptop i push power button it wont boot up but leds in front flash 4 times
Try holding down the power button instead of just pushing it. I had this problem with my HP dv7 and holding the power button down for around 5 seconds worked for me. Also make sure that its plugged in to a power source.

61uwx10ba. no power to any boards but power supply.
have you reched around the new soldering area carefully, check for solder spills or drops in the printed circuit, also another thing to look for is some of those replacement stk do not hold their weight, you might want to take them out and try the old ones to see if you recover tv power.

It's not coming on probably because the safety sees a short and is sparing you smoke damage. Double check to make sure any solder didn't cross or drop to another set of solder joints on the bottom. You might be able to get a service manual from here that could tell you more about the lights -> https://www.manualsparadise.com/ShowProductsForModel.do?model=M22931911

Hitachi 53UDX10B power button flashes, chirping noise, LEDs flash
The convergence issue might not affect the TV to the point of not turning ON.
The chirping noise you hear, it means there is a short circuit in the circuitry, possible the HOT or power supply assembly.

Front power indicator blinks, clicking/high pitch sound
  1. This how to is to repair hard drive, software and some firmware issues that can arise on specific cable DVR and DAC and DCT boxes, First instructions are for Scientific Atlanta hardware. Firstly, one should be certain that the cable box has the coax (cable antenna wire) hooked up to the CABLE IN or RF IN on the box itself and be connected to a "hot" outlet - one that you KNOW works. Test it by connecting a TV directly to outlet. If you get a weak signal, the box will too. Digital boxes require a clean SNR. Remove in-line "surge protectors" on the coax. These prevent the signal from being sent by your cable provider to your box.
  2. Scientific Atlanta DVR or High Def boxes:These need to be "booted" or reset when certain errors occur. No audio on certain channels when SAP is NOT set to ON and confounding error codes that one can't seem to get out of. Common yet confounding errors are : No Audio on DVR Playback. No Audio on Certain Various Channels (ruling out SAP which can be enabled through the box, OR the television set itself) there are easy ways to test. If some channels audio is in Spanish when they are normally in English...the obviously you will check SAP first.
  3. Disc errors. On screen error on your TV that says something like..."there are problems with your storage disc.." or upon DVR playback instead of playing your program it loops upon itself and plays nothing.
  4. two different steps to reboot box: Simultaneously press VOL+ VOL- and "INFO" buttons on box itself, not from remote. Box will then display "bOOt" and shut down totally. Do not press ANY buttons or try to power on said box. Wait for the correct time to display on the box. This process can take anytime from 40 seconds to hours, depending on how fast the cable company's servers are responding at that moment and whether or not you have enough of a cable signal to fire up the download process. If you call customer service for your provider if this does not work, most likely a truck roll will be run for a tech to come out to your residence to fix the signal issue.
  5. When the correct time display is on the Scientific Atlanta box, THEN power on box and problems should be solved. An alternate way to reboot box is to simply unplug unit from power supply and replugging it in. Simply powering it on and off with the POWER ON button will not solve anything.
  6. On a Motorola box and/or DVR, the easy VOL+ VOL- and INFO will not work to reboot. Remove AC power plug from wall socket and wait 30 seconds to a minute while box is powered ON. Plug back in to wall socket.Box will "do it's own thing" and power itself on on it's own after the cycle has been successful (30 - 60 seconds) and the box should power itself back to the ON without you doing anything. Time will not display on Motorola"General Instrument boxes unless you set it up to do so in the settings mode.
  7. Common IControl/On Demand errors:
  8. MOTOROLA BOX Error 225 : A billing lock to prevent you from ordering pay per views. If your account is past due, or if you have an order to move to a new address in the service provider's "system", this is a preventive measure to keep customers from loading up tons of expensive pay per views and skipping out. Your cable company cannot over-ride this error. If you are not in above situations, your provider can "up" the limit on the box and clear it so you can order PPV through your remote control.
  9. SCIENTIFIC ATLANTA: for above mentioned error code, your SA box will display not a code but a prompt to contact your provider by telephone. Same issue.
  10. MOTOROLA BOX ERRORS 204...203.. 207..these may be easily solved by simply reseating the coax and then rebooting box.
  11. SCIENTIFIC ATLANTA ERRORS 2207: reboot box. This is a general code meaning the box has lost contact with the server. All of your iControl /On Demand orders come through your local cable head-end's servers. If and when it gets overloaded and times out, error 2207/207 will happen. Most of the time this is temporary. Reboot box, try again in 15-20 minutes.
  12. DVR BOX not displaying/recording/playing items:
  13. Reboot. Good chance of fixing.
  14. If your TV displays "One Moment, Please. Your Channel Should Be Available Shortly..." this is a SIGNAL issue. Reseat the line running from wall to the CABLE/RF IN on the box and at the outlet at wall. If no joy, call cable operator.
