Question about Sony FD Trinitron WEGA KV-34HS420 34" TV
Hi, The number of flashes (on/off) is indicative of a code. The code represents a particular problem. For example on some versions, 3 blinks indicate diagnostic mode where the builtin protection has kicked in (very likely a powersupply problem), 5 blinks indicates a video controller fault (possibly picture tube drives). Unfortunately this require the services of a qualified TV professional very familiar with Sony WEGA. In some cases this type of errors can be corrected by a hard reset, while others still would require board replacement (expensive) or hopefully component level repair. Good luck and post back should you need further information. kind regards.

Check the power supply mainboard if there are inflated electrolytic capacitors, to replace them.

The flashing timer light blinks out a code, where it flashes some number of times, pauses, then repeats. The code indicates what fault is keeping the set from coming on. Unfortunately, all the codes tend to mean that there is some electronic problem with the TV. Unless you have some electronic servicing skills and the necessary equipment to troubleshoot the problem, you'll need to have set checked by a professional. For any code there can be many causes, so I can't offer any other advice.
This might be a good time to check sale prices on LCD sets. Let a technician check the set and give an estimate for the repair, then decide.
