Toshiba 32A42 TV - Red Light Flashing Tech said...

We bought our Toshiba 32a42 TV in2003. Picture is fantastic. Never a problem. Went to turn on the other morning and the red light just flashes. Unplugged for 4 hours didn't help. Took to a repair shop. Says the High Voltage Transformer is bad, too expensive to fix. Your opinion? I want to make sure he just isn't trying to get my tv to fix on his own.

Toshiba 32A42/32A42A. Just moved tv to bedroom, worked great for 2 days, now the picture has vertical lines. Turned it off for 15 minutes, picture came on, 10 minutes later lines appear again. Anyway to...


It sounds that there is any loose solder terminals at the main board, especially with the vertical scan output section circuit. It will be best to contact any service technician to get it repaired. Gopakumar Gopalan Google

Clicks but won't come on, no picture


Most likely you have a horizontal/high voltage problem. There are no user servicable parts in this set and high voltage is dangerous to work with. Have a repair shop check it for you. Thanks. These are good sets so it is worth a check out.

TOSHIBA 32A42 WILL NOT TURN ON/OFF WITH REMOTE


Check the remote control for its infrared emission. Check it with fresh batteries. Check it by pressing all the keys. You can detect the presence of infra-red emission from the remote control, using a cell-phone camera. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. In some cases, the remote control might need to clean.

Kids.


Dead, led flashing red/green at first, then going to red standby
Replace C604 (1000uF, 16v) elec. cap. It is in the decoupling circuit for the 5 volt supply
Red led blinks on / off, TV does not turn via power button and/or remote but after 20 minutes or so it turns on and works fine
Replace R902, R901, R905, R903, R900A, Q902, and possibly the two (one small and one large) capacitors in the section labeled as the power supply. The board will be black under the components that are bad. Q902 is an NPN transistor and is hard to find.

Dark picture (HELP)


Open up the back of the set but be very carefull. Notice a large black block with a large red wire that runs up to the picture tube. on one side of that large block where the thick red wire is comming out of are two controls, one should be marked focus or F and one should be marked screen or S. With the set operating normally and not touching anything else, slowly turn the control marked screen or S clockwish till the picture gets bright enough. If you go too bright the set will shut down or you see small thin white lines so back down on the control. then touch up the focus and your good to go. good Luck.
